      Pull kselftest updates from Shuah Khan:
      
       - speed up headers_install done during selftest build
      
       - add generic make nesting support
      
       - add support to select individual tests:
      
         Selftests build/install generates run_kselftest.sh script to run
         selftests on a target system. Currently the script doesn't have
         support for selecting individual tests. Add support for it.
      
         With this enhancement, user can select test collections (or tests)
         individually. e.g:
      
            run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep
      
         Additionally adds a way to list all known tests with "-l", usage with
         "-h", and perform a dry run without running tests with "-n".

        doc: dev-tools: kselftest.rst: Update examples and paths
        selftests/run_kselftest.sh: Make each test individually selectable
        selftests: Extract run_kselftest.sh and generate stand-alone test list
        selftests: Add missing gitignore entries
        selftests: more general make nesting support
        selftests: use "$(MAKE)" instead of "make" for headers_install

      HID: i2c-hid: Enable wakeup capability from Suspend-to-Idle · 203c38fb
      Kai-Heng Feng authored
      Many laptops can be woken up from Suspend-to-Idle by touchpad. This is
      also the default behavior on other OSes.
      
      However, if touchpad and touchscreen contact to each other when lid is
      closed, wakeup events can be triggered inadventertly.
      
      So let's disable the wakeup by default, but enable the wakeup capability
      so users can enable it at their own discretion.

         - Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2.
      
        ASoC:
         - Lots of updates for Intel SOF and SoundWire enablement
         - Replacement of the DSP driver for some older x86 systems; the new
           code was written from scratch, better maintenance expected
         - Helpers for parsing auxiluary devices from the device tree
         - New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359

       "Not a major amount of change, the i915 trees got split into display

      powerpc32: don't adjust unmoved stack pointer in csum_partial_copy_generic() epilogue · e6037a75
      Jason A. Donenfeld authored
      A recent change to the checksum code removed usage of some extra
      arguments, alongside with storage on the stack for those, and the stack
      pointer no longer needed to be adjusted in the function prologue.
      
      But a left over subtraction wasn't removed in the function epilogue,
      causing the function to return with the stack pointer moved 16 bytes
      away from where it should have.  This corrupted local state and lead to
      weird crashes.
      
      This simply removes the leftover instruction from the epilogue.
      
      Fixes: 70d65cd5 ("ppc: propagate the calling conventions change down to csum_partial_copy_generic()")

      fs: fix NULL dereference due to data race in prepend_path() · 09cad075
      Andrii Nakryiko authored
      Fix data race in prepend_path() with re-reading mnt->mnt_ns twice
      without holding the lock.
      
      is_mounted() does check for NULL, but is_anon_ns(mnt->mnt_ns) might
      re-read the pointer again which could be NULL already, if in between
      reads one of kern_unmount()/kern_unmount_array()/umount_tree() sets
      mnt->mnt_ns to NULL.

      Pull pidfd updates from Christian Brauner:
       "This introduces a new extension to the pidfd_open() syscall. Users can
        now raise the new PIDFD_NONBLOCK flag to support non-blocking pidfd
        file descriptors. This has been requested for uses in async process
        management libraries such as async-pidfd in Rust.
      
        Ever since the introduction of pidfds and more advanced async io
        various programming languages such as Rust have grown support for
        async event libraries. These libraries are created to help build
        epoll-based event loops around file descriptors. A common pattern is
        to automatically make all file descriptors they manage to O_NONBLOCK.
      
        For such libraries the EAGAIN error code is treated specially. When a
        function is called that returns EAGAIN the function isn't called again
        until the event loop indicates the the file descriptor is ready.
        Supporting EAGAIN when waiting on pidfds makes such libraries just
        work with little effort.
      
        This introduces a new flag PIDFD_NONBLOCK that is equivalent to
        O_NONBLOCK. This follows the same patterns we have for other (anon
        inode) file descriptors such as EFD_NONBLOCK, IN_NONBLOCK,
        SFD_NONBLOCK, TFD_NONBLOCK and the same for close-on-exec flags.
      
        Passing a non-blocking pidfd to waitid() currently has no effect, i.e.
        is not supported. There are users which would like to use waitid() on
        pidfds that are O_NONBLOCK and mix it with pidfds that are blocking
        and both pass them to waitid().
      
        The expected behavior is to have waitid() return -EAGAIN for
        non-blocking pidfds and to block for blocking pidfds without needing
        to perform any additional checks for flags set on the pidfd before
        passing it to waitid(). Non-blocking pidfds will return EAGAIN from
        waitid() when no child process is ready yet. Returning -EAGAIN for
        non-blocking pidfds makes it easier for event loops that handle EAGAIN
        specially.
      
        It also makes the API more consistent and uniform. In essence,
        waitid() is treated like a read on a non-blocking pidfd or a recvmsg()
        on a non-blocking socket.
      
        With the addition of support for non-blocking pidfds we support the
        same functionality that sockets do. For sockets() recvmsg() supports
        MSG_DONTWAIT for pidfds waitid() supports WNOHANG. Both flags are
        per-call options. In contrast non-blocking pidfds and non-blocking
        sockets are a setting on an open file description affecting all
        threads in the calling process as well as other processes that hold
        file descriptors referring to the same open file description. Both
        behaviors, per call and per open file description, have genuine
        use-cases.
      
        The interaction with the WNOHANG flag is documented as follows:
      
         - If a non-blocking pidfd is passed and WNOHANG is not raised we
           simply raise the WNOHANG flag internally. When do_wait() returns
           indicating that there are eligible child processes but none have
           exited yet we set EAGAIN. If no child process exists we continue
           returning ECHILD.
      
         - If a non-blocking pidfd is passed and WNOHANG is raised waitid()
           will continue returning 0, i.e. it will not set EAGAIN. This ensure
           backwards compatibility with applications passing WNOHANG
           explicitly with pidfds"
