With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform dynamic checks using __builtin_object_size(ptr), which when failed will panic the kernel.

memory_failure_dev_pagemap() at the moment assumes base pages (e.g. dax_lock_page()). For devmap with compound pages fetch the compound_head in case a tail page memory failure is being handled. Currently this is a nop, but in the advent of compound pages in dev_pagemap it allows memory_failure_dev_pagemap() to keep working. Without this fix memory-failure handling (i.e. MCEs on pmem) with device-dax configured namespaces will regress (and crash).

Pull char/misc driver fixes from Greg KH: "Here are two small char/misc driver fixes for 5.17-rc2 that fix some reported issues. They are: - fix up a merge issue in the at25.c driver that ended up dropping some lines in the driver. The removed lines ended being needed, so this restores it and the driver works again. - counter core fix where the wrong error was being returned, NULL should be the correct error for when memory is gone here, like the kmalloc() core does. Both of these have been in linux-next this week with no reported issues" * tag 'char-misc-5.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: counter: fix an IS_ERR() vs NULL bug eeprom: at25: Restore missing allocation -

Pull tty/serial driver fixes from Greg KH: "Here are some small bug fixes and reverts for reported problems with the tty core and drivers. They include: - revert the fifo use for the 8250 console mode. It caused too many regressions and problems, and had a bug in it as well. This is being reworked and should show up in a later -rc1 release, but it's not ready for 5.17 - rpmsg tty race fix - restore the cyclades.h uapi header file. Turns out a compiler test suite used it for some unknown reason. Bring it back just for the parts that are used by the builder test so they continue to build. No functionality is restored as no one actually has this hardware anymore, nor is it really tested. - stm32 driver fixes - n_gsm flow control fixes - pl011 driver fix - rs485 initialization fix All of these have been in linux-next this week with no reported problems" * tag 'tty-5.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: kbuild: remove include/linux/cyclades.h from header file check serial: core: Initialize rs485 RTS polarity already on probe serial: pl011: Fix incorrect rs485 RTS polarity on set_mctrl serial: stm32: fix software flow control transfer serial: stm32: prevent TDR register overwrite when sending x_char tty: n_gsm: fix SW flow control encoding/handling serial: 8250: of: Fix mapped region size when using reg-offset property tty: rpmsg: Fix race condition releasing tty port tty: Partially revert the removal of the Cyclades public API tty: Add support for Brainboxes UC cards.
