[PATCH 00/10] drm/msm: some stuff I'm working on for 4.8

Also working on fence-fd support for submit ioctl, but that is
depending on some other patches from Gustavo, and not so much
actually tested yet, so unlikely to be 4.8 material.  But I'll
send an RFC at least in near future.

Main interesting thing here is, I think, shrinker.  Currently
it is limited to purging madvise'd buffers (userspace bo cache)
and vmaps.  Maybe someday I'll setup a swap partition and take
this further, but the more important things to solve in the
short term are keeping the userspace bo-cache from causing
problems on devices w/ less memory (<= 1G) and keeping vmap's
from being a problem on 32b systems.

Rob Clark (10):
  drm/msm: use mutex_lock_interruptible for submit ioctl
  drm/msm: add madvise ioctl
  drm/msm: add put_iova() helper
  drm/msm: shrinker support
  drm/msm: change gem->vmap() to get/put
  drm/msm: wire up vmap shrinker
  drm/msm: deal with arbitrary # of cmd buffers
  drm/msm: bump kernel api version
  drm/msm/rd: split out snapshot_buf helper
  drm/msm/rd: add module param to dump all bo's
