[PATCH net] net: hns3: clear VF down state bit before request link status
by Huazhong Tan 07 Apr '21

07 Apr '21

From: Guangbin Huang <huangguangbin2(a)huawei.com> Currently, the VF down state bit is cleared after VF sending link status request command. There is problem that when VF gets link status replied from PF, the down state bit may still set as 1. In this case, the link status replied from PF will be ignored and always set VF link status to down. To fix this problem, clear VF down state bit before VF requests link status.

Would you please look this over?
by Sarah Johnson 06 Apr '21

06 Apr '21

How has your day been going? I want to share a message that has been spreading all over the internet that concerns the times we are living in. Whether you believe in God or not, this is a must read message! We can see throughout time how we have been slowly conditioned to come to this point where we are on the verge of a cashless society. Would it surprise you to know that the Bible foretold of this event? Don't believe me? This may be the most imporant message you will read in these times...please do not ignore this! This messsage reveals what the Mark of the Beast is, and the meaning behind counting a number people have been pondering for centuries, 666. This message also shares why Barack Obama will be the Antichrist as well as the gospel message. This is truly a message from God! In the Revelation of Jesus Christ given to the apostle John, we read: ..."Also he (the false prophet who deceives many by his miracles) forces everyone — great and small, rich and poor, free and slave — to receive a mark on his right hand or on his forehead preventing anyone from buying or selling unless he has the mark, that is, the name of the beast or the number of its name. This is where wisdom is needed; those who understand should count the number of the beast, for it is the number of a person, and its number is 666" (Revelation 13:16-18 CJB).... Referring to the last generation, this could only be speaking of a cashless money society, which we have yet to see, but are heading towards. Why? Revelation 13:17 tells us that we cannot buy or sell unless we receive the mark of the beast in our right-hand or forehead. We could still buy or sell among one another without receiving the mark if physical money was still currency. It logically deduces itself to this reason. These verses could not be referring to something spiritual because the word references two different physical locations (our right-hand or forehead) stating the mark will be on one "OR" the other. It once again logically deduces itself to this reason. Here is where it really starts to come together. It is shocking how accurate the Bible is concerning the RFID microchip. These are notes from a man named Carl Sanders who worked with a team of engineers to help develop this microchip in the late 1960's. Mr. Carl Sanders sat in seventeen New World Order meetings with heads of state officials such as Henry Kissinger and Bob Gates of the C.I.A. to discuss their agenda on how to bring forth this one-world system. The US government commissioned Mr. Sanders to engineer a microchip for identifying and controlling the peoples of the nations-a microchip that would be placed underneath the skin with a hypodermic needle (a quick, convenient process that would be progressively received by society). Mr. Sanders, along with a group of engineers behind him, with US grant monies provided by US tax dollars, took on this mission and produced a microchip which is powered by a lithium battery, rechargeable through the temperature fluctuations in our skin. Without having knowledge of the biblical scriptures (Carl was not a follower of Jesus at the time), these men spent one and a half million dollars gathering information on the best and most convenient spot to have the microchip placed in the body. Guess what? These researchers observed that the forehead and the back of the hand (the two spots Revelation says the mark will be placed) are not just the most convenient places, but are additionally the only viable spots for fast, consistent temperature fluctuations in the skin to recharge the lithium battery. The microchip is approximately seven millimeters in length, .75 millimeters in diameter, about the size of a grain of rice. It is capable of containing pages of details about you. All of your basic information, work information, crime data, health data, and financial history could be stored on this microchip. Mr. Sanders believes that this microchip, which he regretfully helped invent, is the "mark" mentioned in Revelation 13:16-18. The original Greek word for "mark" is "charagma," which is defined as a "scratch or etching." Additionally it is fascinating to be aware that the number 666 is in fact a word in the original Greek language. The word is "chi xi stigma," with the final word, "stigma," additionally meaning "to stick or prick. Carl believes this is referring to using a hypodermic needle being poked into a person to insert the microchip." Carl Sanders asked a Boston Medical Center doctor what would happen if the lithium contained within the RFID microchip leaked into the body. The doctor responded that if the microchip broke inside a human body, the lithium would cause a severe and painful wound filled with pus. This is what the book of Revelation has to say: "So the first angel poured his bowl on the earth, and a nasty and terrible sore appeared on the people who had the beast’s mark and worshipped its image" (Revelation 16:2 CEB). THE HIDDEN MEANING BEHIND THE NUMBER 666 REVEALED! What I first want to mention, before I share what the Holy Spirit has revealed to me concerning the number of the beast, is that God confirms in threes. We can see this throughout scripture: "For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one" (1 John 5:7 NKJV). "and that He was buried, and that He rose again the third day according to the Scriptures" (1 Corinthians 15:4 NKJV). "...Holy, holy, holy, Lord God Almighty, Who was and is and is to come!" (Revelation 4:8 NKJV). There are many more examples, but I thought I would just share three of them to make the point. Examining Revelation 13:16,17,18, the first group of three I would like to point out is that the mark of the beast is described in three separate verses, 16, 17 and 18. The next three I see is in verse 16, "He causes all..." is followed by three contrasting categories of people, 1 - "both small and great, 2 - rich and poor, 3 - free and slave...". Then unto verse 17, it opens with, "and that no one may buy or sell except one who has...", followed by three explanations of what one must have to buy or sell, 1 - "...the mark 2 - or the name of the beast, 3 - or the number of his name". Now unto verse 18, we read "Let him who has understanding calculate...", which is followed by, 1 - "the number of the beast, 2 - for it is the number of a man: 3 - His number is 666". The last three I see is the number "6" being used three times in a row. The reason I'm making this point about God confirming in three is because it is the key to unlocking how to calculate the number 666. Throughout the centuries there have been people trying to calculate numbers based on titles and names that come up to the number 666 to identify one person, the Antichrist; but from Revelation 13:18, I do not see where God is telling us to count up to 666, but rather to count the number of the beast. This number is identified as 666. So the verse is telling us to count the number 666. What does it mean to count? It means to add up. So how could we add up 666? Remember my previous point about God confirming in threes is key to unlocking the number 666. So logically, what would be the best way to count the number 666? To count it equally by using the rule of three based off the number. We cannot count it equally as 600+60+6, this would also bring us back to the start. We cannot count it as 600+600+600, or 60+60+60 because there are no zeroes in between or at the end of 666. The only logical option is 6+6+6=18. What is interesting is that the verse that reveals for us to count the number itself is verse 18 (there a total of 18 verses in Revelation Chapter 13), being the third verse out of the three verses that describe the mark of the beast in Revelation 13:16,17,18. What is 18 divided by 3? 6. So 3x6=18, or 6+6+6=18. Another interesting point is the only two other combinations (making a total of three possible combinations) for placing a "+" symbol in between 666 are: • 66+6=72 and 6+66=72. • Add both 72's together and you get 144. Why the number 144 is worth our attention is because the verse following Revelation 13:18 is the first time in the Bible where the 144,000 are being described in detail: "Then I looked, and behold, a Lamb standing on Mount Zion, and with Him one hundred and forty-four thousand, having His Father’s name written on their foreheads..." (Revelation 14:1). Now if you add up all three numbers from counting 666 by moving the "+" symbol around, it would be 72+72+18=162. What is compelling about the number 162, is, if you divide 144,000 by 162, you get 888. The name of Jesus in Greek gematria adds up to 888. The New Testament was originally written in the Greek language. Revelation 14:1 not only mentions the 144,000, but also the Lamb who is Jesus. Now what is interesting about the number for Jesus, 888, is that if you apply the same formula that was used to count 666, you get 8+8+8=24. Why the number 24? Revelation chapter 4 tells us there are 24 elders seated around the throne of God. This is the same throne where Jesus sits. Now if you take: • 8+8+8=24 • 8+88=96 • 88+8=96 you get 24+96+96=216. Take 144,000 divided by 216 and you get 666. Remember that this was the same exact formula we used to count the number 666 that ultimately brought forth the number 888. Here is a quick recap to demonstrate how this formula confirms itself as being the true way to count 666: 1: 6+6+6=18 » 66+6=72 » 6+66=72 » 18+72+72=162 2: 144,000 divided by 162=888 3: 8+8+8=24 » 88+8=96 » 8+88=96 » 24+96+96=216 4: 144,000 divided by 216=666 1: 6+6+6=18 » 66+6=72... As you can see, it is perpetual. And remember that we consistently used a formula that worked in threes being the number that God uses for confirmation. With utilizing the same formulation of counting by adding the "+" symbol in between the numbers, why do all these numbers relate in such a way? The book of Revelation contains the use of the number 7 in various forms. For instance 7 seals, 7 trumpets, and 7 bowls. What is interesting about the number 37 (three sevens) is if if you divide any number that contains the same single digit three times in a row, such as 111 to 999, it comes out to the value of if you were to add all three numbers up. For example 888 divided by 37 equals 24. So 8+8+8=24. Or 666 divided by 37 equals 18. So 6+6+6=18. Could this be another way of God's word confirming itself that the mystery behind calculating the number 666 indeed is 18? Another fascinating factor to be aware is that if you add up all the numbers from 1 to 36 (1+2+3...+36), it totals 666. The number 36, as in three sixes? May this be a sign that we need to add up three sixes as opposed to perceiving the number as six-hundred sixty six? Now what may this mean? We know in this world we are identified by numbers in numerous forms. From our birth certificate to social security, also with our drivers license, being identified founded on a system of ruler ship. So it is possible that this RFID chip will comprise a new identification that has a total of 18 characters. "here the wisdom is, the one having the mind let him calculate the number of the wild beast, number for "of human" it is, and the number of it 666" (Revelation 13:1, Greek Translation). The Greek word "anthrōpos" being used in verse 18 where it says "of human" is the Greek strongs concordance G444. The first two definitions of the word are "a human being, whether male or female", and, "generically, to include all human individuals". Could the number of the beast apply to all mankind? In the Greek (the New Testament was originally written in the Greek language), and other translations, you will notice the beast is described as an "it", instead of "him". The reason I'm making this point is because when a translation says "His number is 666", this would imply a singular person, the Antichrist. But by saying "the number of it 666", implies that it is of the beast system as a whole. We can know the number of the beast cannot be to identify products (like a new barcode) to buy or sell because scripture says we cannot buy or sell without the number of the beast. What am I getting at? There will be instances where you could buy something someone made themselves and it wouldn't have a store branded identification on it. But for this number to be in our chips, that is where it must be to conclude ultimately that we cannot buy or sell without having the number of the beast. As previously mentioned in Revelation 13:18, the number of the beast (6+6+6=18) is a "human number", definition "generically, to include all human individuals". May this be the title of the beast, the number of its name? The one-world beast system that's identified by 18 characters? This may fit the scriptures that speaks of a mark that we must have to buy or sell in our right-hand or forehead, and that it also includes the number of the beast, throughout a future cashless money society.

"Why did the Biden campaign choose 30330? 2020 divided by 666 = 3.0330 Who believes this to be a coincidence? October 2020 Isaiah 53:6 Someone said we are being whipsawed in 2020. Truly a great division is taking place between good and evil—both symbolically and literally (riots, unrest, politics). If you take the current year 2020 and divide it by the number 666 (known for its satanic implications) you will get the number 30330 (repeated). This number 30330 happens to be the number used to vote for Joe Biden and Kamala Harris. Freaky? Supernatural? Odd for sure. Whatever this means, it doesn’t seem good to me. First, why would anyone knowingly choose those particular numbers for their campaign? If they weren’t knowingly chosen, then it appears to be a supernatural act by the evil one himself and I would want to change those numbers ASAP. And if the numbers were chosen knowing their significance, are you satanic? Is this campaign satanic? Either way I do not believe this is a coincidence. And one thing is certain, 2020 is truly being divided by Satan. He is the master deceiver and spreader of chaos. Jesus calls him the father of lies." So I looked up this number 30330 concerning Joe Biden, and I found this information: If you send a text to that number (at that time), you would get a response asking to support Joe's campaign to take down Donald Trump, with one part in caps saying "CHIP IN >>" pointing to a link to go and donate. "CHIP IN"? Obama has used this phrase in the past on his twitter and people believe it is a subliminal message to receive the mark of the beast, that is to say the implantable RFID microCHIP that will go IN our body. The scriptures warns us in the last days that a false prophet will stand up doing miracles deceiving many to receive the mark of the beast: ..."And the beast was taken, and with him the false prophet that wrought the signs in his sight, wherewith he deceived them that had received the mark of the beast and them that worshipped his image: they two were cast alive into the lake of fire that burneth with brimstone" (Revelation 19:20 ASV)... At ALL COSTS, resist the mark! "Then a third angel followed them, saying with a loud voice, "If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name" (Revelation 14:9-11). We are living in very prophetic times with very important Biblical prophecies being fulfilled. When Donald Trump recognized Jerusalem as capital of Israel on December 6th of '17, this was a huge step to fulfill the Third Temple foretold within the the scriptures. God's holy Word's alerts us that the Antichrist will seat himself in this temple: "...and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God" (2 Thessalonians 2:3-4). Within the Islamic religion, there is a figure called the Mahdi, referred to as their messiah who they are waiting to be revealed. There are various testimonies from people on the internet who believe this man shall be Barack Obama who is to be the biblical Antichrist. I have had unusual dreams about Obama. He got on stage declaring himself to be a follower of Christ with no affiliation to the Muslim faith, but was later revealed by his family that he indeed is a religious Muslim. So what's in the name? The meaning of someones name can say a lot about a person. God throughout history has given names to people that have a specific meaning tied to their lives. How about the name Barack Obama? Let us take a look at what may be hiding beneath the surface... Jesus says, "And He said to them, 'I saw Satan fall like lightning from heaven'" (Luke 10:18). In Hebrew, the name "Barack" means "lighting", and the use of "Bama" (Strongs Hebrew word 1116) is used to mean the "heights" of heaven. The day after the election of Barack Obama (11/04/08), the prevailing pick three lotto numbers in Illinois (Obama’s domestic state) for 11/5/08 were 666. Obama was a U.S. senator for the state of Illinois, and his zip code was 60606. Regardless, whoever seats himself in the future Third Temple that is to be built in Jerusalem, declaring himself to be God WILL BE THE ANTICHRIST. DO NOT BE LEAD ASTRAY. Why do we need Jesus? "for all have sinned and fall short of the glory of God" (Romans 2:23). "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord" (Romans 6:23). Our good works can't save us from our sins. If we step before a judge, being guilty of a criminal offense, the judge will not judge us by the good that we have carried out, but rather the crimes we have committed. If we as fallen humanity, created in God's image, pose this kind of justice, how much more a perfect, righteous, and Holy creator? God has introduced to us His ethical law's by the ten commandments received by Moses at Mt. Siani. These legal guidelines were not given so we may be justified, but so that we might see the need for a saviour. They are the mirror of God's character of what He has put in each of us, with our conscious bearing witness that we all know that it is an act of evil to steal, lie, dishonor our mother and father, and so on. We may try to follow all the ethical guidelines of the ten commandments, but we'll never catch up to them to be justified before a Holy God. That same word of the law given to Moses became flesh over 2000 years ago in the body of Jesus Christ. He was brought forth to be our justification by perfectly fulfilling the law, living a sinless life that solely God could accomplish. The distance between us and the law of God can never be reconciled by our very own merit, but the arm of Jesus is stretched out by the grace and mercy of God. And if we are to seize hold of, by faith in Him, He'll pull us up being the one to justify us. As in the court of law, if someone steps in and pays your fine, even though you're guilty, the judge can do what is legal and just and let you go free. That is what Jesus did almost 2000 years in the past on the cross. It was a legal transaction being fulfilled in the spiritual realm by the shedding of His blood, with His last words being, "...It is finished!..." (John 19:30). Now why did Jesus have to die for us? Because God is Holy and just, the wrath that belongs to us could not go unnoticed. Because of the perfect righteousness and justice of God's character, it must be dealt with, it must be quenched and satisfied. For God takes no pleasure in the demise of the wicked (Ezekiel 18:23). That is why in Isaiah chapter 53, where it speaks of the coming Messiah and His soul being a sacrifice for our sins, why it says it satisfied God to crush His only begotten Son. That is due to the fact the wrath that we deserve was justified by being poured out upon His Son. For if it were to be poured out upon us who deserve it, we would all die and go to hell. God created a means of escape by pouring it out on His Son who's soul could not stay in Hades, but was raised and seated on the right hand of God in power. So now after we put on the Lord Jesus Christ (Romans 13:14), God no longer looks at the individual who deserves His wrath, but the glorious image of His perfect Son residing in our hearts, justifying us as if we obtained the wrath we deserve, making a means of escape from the curse of death. Now what we must do is turn from our sins and trust in the saviour, confessing and forsaking our sins. That is not just a head knowledge of believing in Jesus, but rather receiving His words, taking them to heart. In which we no longer live to practice sin, but turn away from our sins and practice righteousness: "Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God" (1 Corinthians 6:9-11). By doing so we will become transformed into the image of God by faith in His Son Christ Jesus Who's inclined to present the Holy Spirit to whoever ask of Him: "Most assuredly, I (Jesus) say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not marvel that I said to you, 'You must be born again.' (John 3:5-6). "But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His" (Romans 8:9). What are you waiting for? Our heavenly Father only wants the best for us all, restoring every little thing this world has stolen from us. That is what it means to be "holy". To be made whole. He is waiting to hear from you. That God given tongue to speak language, by way of faith, pray to Him, ask Him to forgive you by confessing to Him your sins and be willing to forsake them; that you receive the sacrifice of His Son Jesus on the cross, and that you need His Holy Spirit living inside you reworking you into a child of the living God. Jesus says, "but whoever drinks of the water that I shall give him (the Holy Spirit) will never thirst. But the water that I shall give him will become in him a fountain of water springing up into everlasting life." Did you realize that Jesus spoke more about hell than anyone else in the scriptures, even more than He spoke about heaven?! For this very reason He was brought forth to die for us, to deliver us from this place that we earned by our sins. He describes hell as a real place where, "Their worm does not die And the fire is not quenched" (Mark 9:44). And where, "There will be weeping and gnashing of teeth..." (Luke 13:28). Jesus tells us who to fear, "And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell" (Matthew 10:28). "Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. Also there was no more sea. Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from heaven saying, 'Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God. And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.' Then He who sat on the throne said, 'Behold, I make all things new.' And He said to me, 'Write, for these words are true and faithful.' And He said to me, 'It is done! I am the Alpha and the Omega, the Beginning and the End. I will give of the fountain of the water of life freely to him who thirsts. He who overcomes shall inherit all things, and I will be his God and he shall be My son. But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.'" (Revelation 21:1-8).

Hi

06 Apr '21

Hi there, I want to share a message that has been spreading all over the internet that concerns the times we are living in. Whether you believe in God or not, this is a must read message! We can see throughout time how we have been slowly conditioned to come to this point where we are on the verge of a cashless society. Would it surprise you to know that the Bible foretold of this event? Don't believe me? This may be the most imporant message you will read in these times...please do not ignore this! This messsage reveals what the Mark of the Beast is, and the meaning behind counting a number people have been pondering for centuries, 666. This message also shares why Barack Obama will be the Antichrist as well as the gospel message. This is truly a message from God! In the Revelation of Jesus Christ given to the apostle John, we read: ...."He (the false prophet who deceives many by his miracles) forces everyone—the small and great, the rich and poor, the free and slaves—to have a mark put on their right hand or on their forehead. He will not allow anyone to make a purchase or sell anything unless the person has the mark with the beast’s name or the number of its name. This calls for wisdom. Let the one who understands calculate the beast’s number, for it’s a human being’s number. Its number is six hundred sixty-six" (Revelation 13:16-18 CEB)..... Referring to the last generation, this could only be speaking of a cashless money society, which we have yet to see, but are heading towards. Why? Revelation 13:17 tells us that we cannot buy or sell unless we receive the mark of the beast in our right-hand or forehead. We could still buy or sell among one another without receiving the mark if physical money was still currency. It logically deduces itself to this reason. These verses could not be referring to something spiritual because the word references two different physical locations (our right-hand or forehead) stating the mark will be on one "OR" the other. It once again logically deduces itself to this reason. Here is where it really starts to come together. It is shocking how accurate the Bible is concerning the RFID microchip. These are notes from a man named Carl Sanders who worked with a team of engineers to help develop this microchip in the late 1960's. Mr. Carl Sanders sat in 17 New World Order meetings with heads-of-state officials such as Henry Kissinger and Bob Gates of the C.I.A. to discuss their agenda on how to bring about this one-world system. The government commissioned Carl Sanders to invent a microchip for identifying and controlling the peoples of the world-a microchip that might be inserted underneath the skin with a hypodermic needle (a quick, convenient process that would be gradually accepted by society). Carl Sanders, with a crew of engineers behind him, with US grant monies supplied by tax dollars, took on this challenge and designed a microchip that is powered by a lithium battery, rechargeable through the temperature changes in our skin. With out the knowledge of the Bible (Mr. Sanders was not a follower of Jesus at the time), these engineers spent one-and-a-half-million dollars doing research on the best and most convenient spot to have the microchip placed within the body. Guess what? These researchers determined that the forehead and the back of the hand (the two locations Revelation says the mark will be received) are not only the most convenient places, however are additionally the only viable locations for rapid, consistent temperature changes inside the skin to recharge the lithium battery. The microchip is approximately 7 millimeters in length, .75 millimeters in diameter, about the size of a grain of rice. It's capable of holding pages upon pages of details about you. All of your common information, work data, crime records, health records, and financial information will be saved on this microchip. Mr. Sanders believes that this microchip, which he regretfully helped engineer, is the "mark" mentioned in Revelation 13:16-18. The Greek word for "mark" is "charagma," which is defined as a "scratch or etching." It's also fascinating to observe that the number 666 is actually a word in the original Greek. This word being "chi xi stigma," with the final part, "stigma," additionally meaning "to stick or prick. Carl believes that is referencing to using a hypodermic needle being poked in the human flesh to insert the microchip." Carl asked a Boston Medical Center doctor what would happen if the lithium contained within the RFID microchip leaked into the body. The doctor responded that if the microchip broke inside a human body, the lithium would cause a severe and painful wound filled with pus. This is what the book of Revelation has to say: "So the first angel poured his bowl on the earth, and a nasty and terrible sore appeared on the people who had the beast’s mark and worshipped its image" (Revelation 16:2 CEB). THE HIDDEN MEANING BEHIND THE NUMBER 666 REVEALED! What I first want to mention, before I share what the Holy Spirit has revealed to me concerning the number of the beast, is that God confirms in threes. We can see this throughout scripture: "For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one" (1 John 5:7 NKJV). "and that He was buried, and that He rose again the third day according to the Scriptures" (1 Corinthians 15:4 NKJV). "...Holy, holy, holy, Lord God Almighty, Who was and is and is to come!" (Revelation 4:8 NKJV). There are many more examples, but I thought I would just share three of them to make the point. Examining Revelation 13:16,17,18, the first group of three I would like to point out is that the mark of the beast is described in three separate verses, 16, 17 and 18. The next three I see is in verse 16, "He causes all..." is followed by three contrasting categories of people, 1 - "both small and great, 2 - rich and poor, 3 - free and slave...". Then unto verse 17, it opens with, "and that no one may buy or sell except one who has...", followed by three explanations of what one must have to buy or sell, 1 - "...the mark 2 - or the name of the beast, 3 - or the number of his name". Now unto verse 18, we read "Let him who has understanding calculate...", which is followed by, 1 - "the number of the beast, 2 - for it is the number of a man: 3 - His number is 666". The last three I see is the number "6" being used three times in a row. The reason I'm making this point about God confirming in three is because it is the key to unlocking how to calculate the number 666. Throughout the centuries there have been people trying to calculate numbers based on titles and names that come up to the number 666 to identify one person, the Antichrist; but from Revelation 13:18, I do not see where God is telling us to count up to 666, but rather to count the number of the beast. This number is identified as 666. So the verse is telling us to count the number 666. What does it mean to count? It means to add up. So how could we add up 666? Remember my previous point about God confirming in threes is key to unlocking the number 666. So logically, what would be the best way to count the number 666? To count it equally by using the rule of three based off the number. We cannot count it equally as 600+60+6, this would also bring us back to the start. We cannot count it as 600+600+600, or 60+60+60 because there are no zeroes in between or at the end of 666. The only logical option is 6+6+6=18. What is interesting is that the verse that reveals for us to count the number itself is verse 18 (there a total of 18 verses in Revelation Chapter 13), being the third verse out of the three verses that describe the mark of the beast in Revelation 13:16,17,18. What is 18 divided by 3? 6. So 3x6=18, or 6+6+6=18. Another interesting point is the only two other combinations (making a total of three possible combinations) for placing a "+" symbol in between 666 are: • 66+6=72 and 6+66=72. • Add both 72's together and you get 144. Why the number 144 is worth our attention is because the verse following Revelation 13:18 is the first time in the Bible where the 144,000 are being described in detail: "Then I looked, and behold, a Lamb standing on Mount Zion, and with Him one hundred and forty-four thousand, having His Father’s name written on their foreheads..." (Revelation 14:1). Now if you add up all three numbers from counting 666 by moving the "+" symbol around, it would be 72+72+18=162. What is compelling about the number 162, is, if you divide 144,000 by 162, you get 888. The name of Jesus in Greek gematria adds up to 888. The New Testament was originally written in the Greek language. Revelation 14:1 not only mentions the 144,000, but also the Lamb who is Jesus. Now what is interesting about the number for Jesus, 888, is that if you apply the same formula that was used to count 666, you get 8+8+8=24. Why the number 24? Revelation chapter 4 tells us there are 24 elders seated around the throne of God. This is the same throne where Jesus sits. Now if you take: • 8+8+8=24 • 8+88=96 • 88+8=96 you get 24+96+96=216. Take 144,000 divided by 216 and you get 666. Remember that this was the same exact formula we used to count the number 666 that ultimately brought forth the number 888. Here is a quick recap to demonstrate how this formula confirms itself as being the true way to count 666: 1: 6+6+6=18 » 66+6=72 » 6+66=72 » 18+72+72=162 2: 144,000 divided by 162=888 3: 8+8+8=24 » 88+8=96 » 8+88=96 » 24+96+96=216 4: 144,000 divided by 216=666 1: 6+6+6=18 » 66+6=72... As you can see, it is perpetual. And remember that we consistently used a formula that worked in threes being the number that God uses for confirmation. With using the identical formulation of counting by adding the "+" symbol in between the numbers, why do all these numbers relate in such a way? The book of Revelation contains the use of the number 7 in various forms. For instance 7 seals, 7 trumpets, and 7 bowls. What is interesting about the number 37 (three sevens) is if if you divide any number that contains the same single digit three times in a row, such as 111 to 999, it comes out to the value of if you were to add all three numbers up. For example 888 divided by 37 equals 24. So 8+8+8=24. Or 666 divided by 37 equals 18. So 6+6+6=18. Could this be another way of God's word confirming itself that the mystery behind calculating the number 666 indeed is 18? Yet another fascinating point to observe is that if you add up all the numbers from 1 to 36 (1+2+3...+36), it totals 666. The number 36, as in three sixes? Could this be a sign that we need to add up three sixes instead of perceiving the number as six-hundred sixty six? Now what may this suggest? We all know in this world we are identified by numbers in numerous forms. Starting from our birth certificates to our social security card, as well as our drivers license, being identified founded on a system of ruler ship. So it's possible that this RFID chip will include a brand new identification that has a total of 18 characters. "here the wisdom is, the one having the mind let him calculate the number of the wild beast, number for "of human" it is, and the number of it 666" (Revelation 13:1, Greek Translation). The Greek word "anthrōpos" being used in verse 18 where it says "of human" is the Greek strongs concordance G444. The first two definitions of the word are "a human being, whether male or female", and, "generically, to include all human individuals". Could the number of the beast apply to all mankind? In the Greek (the New Testament was originally written in the Greek language), and other translations, you will notice the beast is described as an "it", instead of "him". The reason I'm making this point is because when a translation says "His number is 666", this would imply a singular person, the Antichrist. But by saying "the number of it 666", implies that it is of the beast system as a whole. We can know the number of the beast cannot be to identify products (like a new barcode) to buy or sell because scripture says we cannot buy or sell without the number of the beast. What am I getting at? There will be instances where you could buy something someone made themselves and it wouldn't have a store branded identification on it. But for this number to be in our chips, that is where it must be to conclude ultimately that we cannot buy or sell without having the number of the beast. As previously mentioned in Revelation 13:18, the number of the beast (6+6+6=18) is a "human number", definition "generically, to include all human individuals". Could this be the identification of the beast, the number of its name? The one-world beast system that's identified by 18 characters? This may fit the scriptures that speaks of a mark that we must have to buy or sell in our right-hand or forehead, and that it additionally consists of the number of the beast, during a future cashless money society. Go to: http://bible-freedom.org http://je-schools.com/index.php/campaigns[CAMPAIGN_UID/track-url/hh974bmo22… http://je-schools.com/index.php/campaigns/so9648ll8ob7c/track-url/hh974bmo2… http://je-schools.com/index.php/campaigns/so9648ll8ob7c/track-url/hh974bmo2…] to see all the proof! "Why did the Biden campaign choose 30330? 2020 divided by 666 = 3.0330 Who believes this to be a coincidence? October 2020 Isaiah 53:6 Someone said we are being whipsawed in 2020. Truly a great division is taking place between good and evil—both symbolically and literally (riots, unrest, politics). If you take the current year 2020 and divide it by the number 666 (known for its satanic implications) you will get the number 30330 (repeated). This number 30330 happens to be the number used to vote for Joe Biden and Kamala Harris. Freaky? Supernatural? Odd for sure. Whatever this means, it doesn’t seem good to me. First, why would anyone knowingly choose those particular numbers for their campaign? If they weren’t knowingly chosen, then it appears to be a supernatural act by the evil one himself and I would want to change those numbers ASAP. And if the numbers were chosen knowing their significance, are you satanic? Is this campaign satanic? Either way I do not believe this is a coincidence. And one thing is certain, 2020 is truly being divided by Satan. He is the master deceiver and spreader of chaos. Jesus calls him the father of lies." So I looked up this number 30330 concerning Joe Biden, and I found this information: If you send a text to that number (at that time), you would get a response asking to support Joe's campaign to take down Donald Trump, with one part in caps saying "CHIP IN >>" pointing to a link to go and donate. "CHIP IN"? Obama has used this phrase in the past on his twitter and people believe it is a subliminal message to receive the mark of the beast, that is to say the implantable RFID microCHIP that will go IN our body. The Bible warns us in the end times that a false prophet will stand up performing miracles deceiving many to acquire the mark of the beast: ...."Then the beast was captured, and with him the false prophet who worked signs in his presence, by which he deceived those who received the mark of the beast and those who worshiped his image" (Revelation 19:20).... At ALL COSTS, resist the mark! "Then a third angel followed them, saying with a loud voice, "If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name" (Revelation 14:9-11). We are dwelling in very prophetic times with major Biblical prophecies coming to pass. When Donald Trump acknowledged Jerusalem as capital of Israel on December 6 2017, this was a large step to bring forth the Third Temple foretold within the words of God. God's word warns us that the Antichrist will seat himself in this temple: "...and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God" (2 Thessalonians 2:3-4). Within the Islamic religion, they have a person called the Mahdi, referred to as their messiah who they are awaiting to be revealed. There are various testimonies from people online who believe this man shall be Barack Obama who is to be the biblical Antichrist. I personally have had strange dreams concerning Obama. He got on stage claiming to be a follower of Jesus with no affiliation to the Muslim faith, however it was later revealed by his own family members that he certainly is a religious Muslim. So what's in the name? The meaning of someones name can say a lot about a person. God throughout history has given names to people that have a specific meaning tied to their lives. How about the name Barack Obama? Let us take a look at what may be hiding beneath the surface... Jesus says, "And He said to them, 'I saw Satan fall like lightning from heaven'" (Luke 10:18). In Hebrew, the name "Barack" means "lighting", and the usage of "Bama" (Strongs Hebrew phrase 1116) is used to mean the "heights" of heaven. The day following the election of Barack Obama (11/04/08), the triumphing pick three lotto numbers in Illinois (Obama’s home state) for 11/5/08 were 666. Obama had been U.S. senator for Illinois, and his zip code was 60606. Regardless, whomsoever seats themselves in the future Third Temple that is to be built in Jerusalem, declaring themselves to be God IS THE ANTICHRIST. DO NOT BE DECEIVED. Why do we need Jesus? "for all have sinned and fall short of the glory of God" (Romans 2:23). "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord" (Romans 6:23). Our good works can't save us. If we step before a judge, being responsible for breaking the law, the judge won't judge us by the good that we have accomplished, rather the crimes we have committed. If we as fallen humanity, created in God's image, pose this type of moral justice, how much more a perfect, righteous, and Holy God? God has introduced to us His ethical law's by way of the ten commandments received by Moses at Mt. Siani. These laws were not given so we can be justified, however so that we may see the need for a savior. They're the mirror of God's character of what He has put in each of us, with our conscious bearing witness that we know that it's wrong to steal, lie, dishonor our parents, and so on. We can attempt to follow all the ethical laws of the ten commandments, however we will never catch up to them to be justified before a Holy God. The same word of the law given to Moses manifested as flesh over 2000 years ago inside the body of Jesus Christ. He was brought forth to be our justification by perfectly fulfilling the commandments of God, living a sinless life that only God could fulfill. The distance between us and the law can never be reconciled by our very own merit, but the arm of Jesus is stretched out by the grace and mercy of God. And if we are to seize hold of, by way of faith in Him, He will pull us up being the one to justify us. As inside the court of law, if someone steps in and pays your fine, despite the fact that you're guilty, the judge can do what's legal and just and let you go free. That is what Jesus did almost 2000 years in the past on the cross. It was a legal transaction being fulfilled inside the spiritual realm by the shedding of His blood, with His last words being, "...It is finished!..." (John 19:30). So why did Jesus have to die for us? Due to the fact that God is Holy and just, the wrath that belongs to us could not be brushed away. Because of the perfect righteousness and justice of God's character, it must be dealt with, it must be quenched and satisfied. For God takes no pleasure in the demise of the wicked (Ezekiel 18:23). That is why in Isaiah chapter 53, the place it speaks of the coming Messiah and His soul being a sacrifice for our sins, why it says it satisfied God to crush His only begotten Son. That is because the wrath that we deserve was justified by being poured out upon His Son. For if it were to be poured out upon us who deserve it, we would all perish and go to hell. God created a means of escape by pouring it out on His Son who's soul could not stay in Hades, however was raised and seated on the right hand of God in power. Now when we put on the Lord Jesus Christ (Romans 13:14), God no longer looks at the individual who deserves His wrath, but rather the glorious image of His perfect Son residing in us, justifying us as if we acquired the wrath we deserve, making a means of escape from the curse of death. Now what we must do is turn from our sins and believe in the savior, confessing and turning from our sins. That is not just a head knowledge of believing in Jesus, instead receiving His words, taking them to heart. In which we no longer live to exercise sin, however turn away from our sins and exercise righteousness: "Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God" (1 Corinthians 6:9-11). By doing so we may come to be transformed into the image of God by way of faith in His Son Christ Jesus Who is inclined to offer the Holy Spirit to whoever ask of Him: "Most assuredly, I (Jesus) say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not marvel that I said to you, 'You must be born again.' (John 3:5-6). "But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His" (Romans 8:9). Now what are you waiting for? Our Father in heaven only wishes the best for us, restoring all the pieces this world has stolen from us. That is what it means to be "holy". To be made whole. He's waiting to hear from you. That God given tongue to speak language, by using faith, pray to Him, ask Him to forgive you by confessing to Him your sins and be willing to forsake them; that you receive the sacrifice of His Son Jesus on the cross, and that you need His Holy Spirit dwelling inside you transforming you into a child of God. Jesus says, "but whoever drinks of the water that I shall give him (the Holy Spirit) will never thirst. But the water that I shall give him will become in him a fountain of water springing up into everlasting life." Did you realize that Jesus spoke more about hell than anybody in God's holy word, even more than He spoke about heaven?! For this very cause He was brought forth to die for us, to deliver us from this place that we earned by our sins against a holy God. He describes hell as a real place where, "Their worm does not die And the fire is not quenched" (Mark 9:44). And where, "There will be weeping and gnashing of teeth..." (Luke 13:28). Jesus tells us who to fear, "And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell" (Matthew 10:28). "Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. Also there was no more sea. Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from heaven saying, 'Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God. And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.' Then He who sat on the throne said, 'Behold, I make all things new.' And He said to me, 'Write, for these words are true and faithful.' And He said to me, 'It is done! I am the Alpha and the Omega, the Beginning and the End. I will give of the fountain of the water of life freely to him who thirsts. He who overcomes shall inherit all things, and I will be his God and he shall be My son. But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.'" (Revelation 21:1-8).

From: Xiang Chen <chenxiang66(a)hisilicon.com> Currently it only support one page map/unmap once a time for dma-map benchmark, but there are some other scenaries which need to support for multi-page map/unmap: for those multi-pages interfaces such as dma_alloc_coherent() and dma_map_sg(), the time spent on multi-pages map/unmap is not the time of a single page * npages (not linear) as it may use block description instead of page description when it is satified with the size such as 2M/1G, and also it can send a single TLB invalidation command to invalidate multi-pages instead of multi-times when RIL is enabled (which will short the time of unmap). So it is necessary to add support for multi-pages map/unmap. Add a parameter "-g" to support multi-pages map/unmap.
