--------------------------------
The upstream changes the interface implementation of the dma map to remove the swiotlb_dma_ops and the dma_direct_ops, which is mentioned in commit 55897af63091 ("dma-direct: merge swiotlb_dma_ops into the dma_direct code") and commit 356da6d0cde3 ("dma-mapping: bypass indirect calls for dma-direct"), so we re-implement the arch-specific direct dma_ops and merge swiotlb_dma_ops.
There is still a risk for 32-bit devices, as there is no guarantee that less than 4G address will be successfully allocated under the current default policy. In this case, it should add "swiotlb=force" to cmdline to use swiotlb map to ensure correctness. Why not use swiotlb in the default policy? One reason is that there are few 32-bit devices today, while dma performance of 64-bit devices will suffer when enabled.

--------------------------------
dma_mask is not sufficient to determine whether the device is 32-bit or not, while coherent_dma_mask is required as well. The addressing capability of a device depends on the minimum of them.
Because 32-bit devices with sunway_dma_ops have to be set to IOMMU_DOMAIN_DMA, which may raise DMA using address allocated by BIOS and lead to iommu exception. So we change dma ops to arch-specific direct dma_ops for 32-bit devices.

Function csum_partial_copy_from_user() copy data from userspace and return checksum result. It used to read 8 bytes data from userspace every time, calculate checksum and store it to the destination, which slowed down the copying process. This patch moves the copying process to the beginning. This patch also rewrites do_csum and move some common codes to header file to avoid duplication.

--------------------------------
sw_64/kvm map the memory of VM instance to QEMU's user space by remap_pfn_range(), which set the vma flag with VM_IO and VM_PFNMAP.
The previous commit set these pages as reserved and follow_pfn() method will get pfn of a PFNMAP vma correctly to fix bug if user do munmap on the vma.
But in generic_file_read_iter() with O_DIRECT flag will call __get_user_pages() and return -EFAULT because of VM_IO and VM_PFNMAP, then bio_iov_iter_get_pages() failed to get the physical pages corresponding to the user virtual address.
To solve this problem, VM_IO and VM_PFNMAP of the vma flag were cleared and set again before release this vma.

We were relying on GNU nm's ability to extract our VDSO symbols, but newer nm will always display version strings after symbol names, which cause so2s.sh to fail to generate vdso-syms.S. Fix so2s.sh to make it work.
Besides, remove the copyright strings from so2s.sh.

The behavior of these system calls is slightly different between architectures, as determined by CONFIG_ARCH_WANT_IPC_PARSE_VERSION symbol. sw64 expect the caller to pass the IPC_64 flag. So switch to old-style semctl and shmctl to maintain libc compatibility.

The user.h is only used for a.out files, and we use generic version instead.

It used to clear VM_IO and VM_PFNMAP of the vma flag, then set again before release this vma to get the physical pages corresponding to the user virtual address.
But __get_user_pages() will fail because of bad pte without VM_PFNMAP if HAVE_GENERIC_GUP and ARCH_HAS_PTE_SPECIAL are enabled.
To fix this issue, remap pages by vm_insert_page() to insert individual pages allocated for guest.

--------------------------------
Original implementation has deprecated sigframe and always use rt_sigframe for signal handler. But glibc remain unchanged, where handler takes $a2 as sigcontext pointer when SA_SIGINFO is not set and compatibility is break. As on sw64, SA_SIGINFO is not only a flag to specify sa_sigaction but also a flag to specify rt_sigframe and rt_sigreturn. It used to setup old sigframe and specify sigreturn for handler if SA_SIGINFO is not set.
To maintain compatibility, this patch set $a1 with exception code and and set $a2 with sigcontext pointer in that case, which seems a mix of modern rt_sigframe and traditional sigframe.
Actually, it is unnecessary to setup rt_sigframe for non SA_SIGINFO handler, because a rt_sigframe is larger than sigframe. Maybe the old sigframe will be reverted some day.

The page flag of the first page after kvm memory pool is incorrectly set to "reserved", which will result in page dumped if user try to apply for it.
Now we exclude the page to fix it.

Dynamic voltage and frequency scaling (DVFS) is a well-known technique to reduce power/or energy consumption of various applications. But in the past, cpu frequency scaling has to be done manually on sw64. Now we add dynamic frequency scaling support, which allows system to scale frequency dynamically according to workload.

Provide the KCS and BT of IPMI system interfaces that system software uses for communication with BMC. Since hardware may occur default errors due to lack of BMC hardware, these interface devices are disabled by default.
To enable IPMI support, one may enable supported BT/KCS interfaces and also select CONFIG_IPMI_HANDLER=y, CONFIG_IPMI_DEVICE_INTERFACE=y and CONFIG_IPMI_SI=y.

--------------------------------
Refactor PME and AER relative codes to use builtin kernel module, one can enable this feature support via selecting CONFIG_PCIEPORTBUS=y, CONFIG_PCIE_PME=y and CONFIG_PCIEAER=y. Since PME and AER events route to CPU by MSI mechanism has been hardcoded and lack of flexibility, we use PCI INTx mechanism to handle these events.

Optimize the use of memb instruction in memset.
Rewrite memcpy and use simd instruction to copy data when src and dest are not co-aligned.
When data size is larger than 2KB, use _nc store instruction to improve performance.
