      Pull btrfs updates from Chris Mason:
       "This has our usual assortment of fixes and cleanups, but the biggest
        change included is Omar Sandoval's free space tree.  It's not the
        default yet, mounting -o space_cache=v2 enables it and sets a readonly
        compat bit.  The tree can actually be deleted and regenerated if there
        are any problems, but it has held up really well in testing so far.
      
        For very large filesystems (30T+) our existing free space caching code
        can end up taking a huge amount of time during commits.  The new tree
        based code is faster and less work overall to update as the commit
        progresses.
      
        Omar worked on this during the summer and we'll hammer on it in
        production here at FB over the next few months"

        for longer story.  The short version:
      
        omapfb and omapdrm have shared low level drivers (omapdss and panel
        drivers), making further development of omapdrm difficult.  After
        these patches omapfb and omapdrm have their own versions of the
        drivers, which are more or less direct copies for now but will diverge
        soon.
      
        This also means that omapfb (everything under drivers/video/fbdev/omap2/)
        is now in maintenance mode, and all new development will be done for
        omapdrm (drivers/gpu/drm/omapdrm/)"

      This isn't used anywhere, so delete it.

      in 2011 in commit bd6709a9 ("x86, NUMA: Make 32bit use common NUMA

      arch/tile: move user_exit() to early kernel entry sequence · 1bb50cad
      Chris Metcalf authored
      This ensures that we always notify context tracking that we
      have exited from user space no matter how we enter the kernel.
      It is similar to how arm64 handles context tracking, for example.
      
      This allows the removal of all the exception_enter() calls that
      were added in commit 49e4e156 ("tile: support CONTEXT_TRACKING and
      thus NOHZ_FULL").

      tile: fix bug in setting PT_FLAGS_DISABLE_IRQ on kernel entry · 9ce815ed
      Chris Metcalf authored
      This flag value is saved in ptregs and used to decide whether
      to disable irqs when returning from the kernel.  Commit 1168df528fe4
      ("tile: don't assume user privilege is zero") performed a bad
      merge from some KVM-enabled code that had not yet been upstreamed.
      
      The only issue with the old code is that we will read the interrupt
      mask in more conditions than we need to (e.g., coming from user
      space when user space has the Interrupt Critical Section bit set, or
      coming from a guest kernel), which is a slow multi-cycle operation.
      This change saves those few cycles in the common case.

      Chris Metcalf authored
      The warning occurs in setup.c, where it is known that it can't be
      a problem, but it's still a good idea to silence the warning.
      The onstack array is converted from an s32 to a u8, which still
      is plenty of range for the values being managed there.
