      fbmem: fix horribly incorrect placement of __maybe_unused · 6dae40ae
      Linus Torvalds authored
      Commit b9d79e4c ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
      places the '__maybe_unused' in an entirely incorrect location between
      the "struct" keyword and the structure name.
      
      It's a wonder that gcc accepts that silently, but clang quite reasonably
      warns about it:
      
          drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute declaration must precede definition [-Wignored-attributes]
          static const struct __maybe_unused seq_operations proc_fb_seq_ops = {
                              ^
      
      Fix it.

      Pull scheduler fixes from Thomas Gleixner:
       "A set of scheduler updates:
      
         - Prevent PSI state corruption when schedule() races with cgroup
           move.
      
           A recent commit combined two PSI callbacks to reduce the number of
           cgroup tree updates, but missed that schedule() can drop rq::lock
           for load balancing, which opens the race window for
           cgroup_move_task() which then observes half updated state.
      
           The fix is to solely use task::ps_flags instead of looking at the
           potentially mismatching scheduler state
      
         - Prevent an out-of-bounds access in uclamp caused bu a rounding
           division which can lead to an off-by-one error exceeding the
           buckets array size.
      
         - Prevent unfairness caused by missing load decay when a task is
           attached to a cfs runqueue.
      
           The old load of the task was attached to the runqueue and never
           removed. Fix it by enforcing the load update through the hierarchy
           for unthrottled run queue instances.
      
         - A documentation fix fot the 'sched_verbose' command line option"

      drm/i915/display: fix compiler warning about array overrun · fec4d427
      Linus Torvalds authored
      intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
      Status Indicator data, but then passes that buffer at offset 10 off as
      an argument to drm_dp_channel_eq_ok().
      
      End result: there are only 4 bytes remaining of the buffer, yet
      drm_dp_channel_eq_ok() wants a 6-byte buffer.  gcc-11 correctly warns
      about this case:
      
        drivers/gpu/drm/i915/display/intel_dp.c: In function ‘intel_dp_check_mst_status’:

             6:14 elapsed
      
      This commit just extends the original array by 2 zero-initialized bytes,
      avoiding the warning.
      
      There may be some underlying bug in here that caused this confusion, but
      this is at least no worse than the existing situation that could use
      random data off the stack.

      smb3: if max_channels set to more than one channel request multichannel · c1f8a398
      Steve French authored
      Mounting with "multichannel" is obviously implied if user requested
      more than one channel on mount (ie mount parm max_channels>1).
      Currently both have to be specified. Fix that so that if max_channels
      is greater than 1 on mount, enable multichannel rather than silently
      falling back to non-multichannel.

      Pull powerpc updates and fixes from Michael Ellerman:
       "A bit of a mixture of things, tying up some loose ends.
      
        There's the removal of the nvlink code, which dependend on a commit in
        the vfio tree. Then the enablement of huge vmalloc which was in next
        for a few weeks but got dropped due to conflicts. And there's also a
        few fixes.
      
        Summary:
      
         - Remove the nvlink support now that it's only user has been removed.
      
         - Enable huge vmalloc mappings for Radix MMU (P9).
      
         - Fix KVM conversion to gfn-based MMU notifier callbacks.
      
         - Fix a kexec/kdump crash with hot plugged CPUs.
      
         - Fix boot failure on 32-bit with CONFIG_STACKPROTECTOR.
      
         - Restore alphabetic order of the selects under CONFIG_PPC.
