Commit 54f7fc25 authored by Linus Torvalds's avatar Linus Torvalds

Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile

Pull tile arch update from Chris Metcalf:
 "The bulk of this change is the tile uapi disintegration.  There is
  also a one-line change in here to enable interrupts in
  do_work_pending() to avoid a WARN_ON in _local_bh_enable_ip()."

* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
  arch/tile: enable interrupts in do_work_pending()
  UAPI: (Scripted) Disintegrate arch/tile/include/asm
