Pull more drm fixes from Daniel Vetter:
 "Dave sends his pull, everyone realizes they've been asleep at the
  wheel and hits send on their own pulls :-/

  Normally I'd just ignore these all because w/e for me and Dave. But
  this time around the latecomers also included drm-intel-fixes, which
  failed to send out a -fixes pull thus far for this release (screwed up
  vacation coverage, despite that 2/3 maintainers were around ... they
  all look appropriately guilty), and that really is overdue to get
  landed.

  And since I had to do a pull request anyway I pulled the other two
  late ones too.

  intel fixes (didn't have any ever since the main merge window pull):
   - gvt fixes (2 cc: stable)
   - fix gpu reset vs mm-shrinker vs wakeup fun (needed a few patches)
   - two gem locking fixes (one cc: stable)
   - pile of misc fixes all over with minor impact, 6 cc: stable, others
     from this window

  exynos:
   - misc minor fixes

  misc:
   - some build/Kconfig fixes
   - regression fix for vm scalability perf test which seems to mostly
     exercise dmesg/console logging ...
   - the vgem cache flush fix for arm64 broke the world on x86, so
     that's reverted again
