Fix it by adding a padding field to `struct ptrace_syscall_info`.

If the size of the error log is too big to send via email, and the sending fails, it wont email any result. This can be confusing for the user who is waiting for an email on the completion of the tests. If it fails to send email, then try again without the log file stating that it failed to send an email. Obviously this will not be of use if the sending of email failed for some other reasons, but it will at least give the user some information when it fails for the most common reason.

The current channel-map control implementation in USB-audio driver may lead to an error message like "control 3:0:0:Playback Channel Map:0: access overflow" when CONFIG_SND_CTL_VALIDATION is set. It's because the chmap get callback clears the whole array no matter which count is set, and rather the false-positive detection. This patch fixes the problem by clearing only the needed array range at usb_chmap_ctl_get().

If a USB2 device wakeup is not enabled/supported the link state may still be in U0 in xhci_bus_suspend(), where it's then manually put to suspended U3 state. Just as with selective suspend the device needs time to enter U3 suspend before continuing with further suspend operations (e.g. system suspend), otherwise we may enter system suspend with link state in U0.

The console part of sisusbvga is broken vs. printk(). It uses in_atomic() to detect contexts in which it cannot sleep despite the big fat comment in preempt.h which says: Do not use in_atomic() in driver code. in_atomic() does not work on kernels with CONFIG_PREEMPT_COUNT=n which means that spin/rw_lock held regions are not detected by it. There is no way to make this work by handing context information through to the driver and this only can be solved once the core printk infrastructure supports sleepable console drivers. Make it depend on BROKEN for now.

Add a range check for avoiding the undefined behavior. As the value can be treated by a signed integer, the max shift should be 30.

From: Alexander Sverdlin <alexander.sverdlin@gmail.com> stable inclusion from stable-5.10.2 commit dadaf794f207ebd94a42bf786f14bdcea95f8ec6 bugzilla: 46859 -------------------------------- commit d96f04d347e4011977abdbb4da5d8f303ebd26f8 upstream. It has been observed that once per 300-1300 port openings the first transmitted byte is being corrupted on AM3352 ("v" written to FIFO appeared as "e" on the wire). It only happened if single byte has been transmitted right after port open, which means, DMA is not used for this transfer and the corruption never happened afterwards. Therefore I've carefully re-read the MDR1 errata (link below), which says "when accessing the MDR1 registers that causes a dummy under-run condition that will freeze the UART in IrDA transmission. In UART mode, this may corrupt the transferred data". Strictly speaking, omap_8250_mdr1_errataset() performs a read access and if the value is the same as should be written, exits without errata-recommended FIFO reset. A brief check of the serial_omap_mdr1_errataset() from the competing omap-serial driver showed it has no read access of MDR1. After removing the read access from omap_8250_mdr1_errataset() the data corruption never happened any more.
