This doesn't remove *all* the struct_mutex, but it covers the worst
of it, ie. shrinker/madvise/free/retire.  The submit path still uses
struct_mutex, but it still needs *something* serialize a portion of
the submit path, and lock_stat mostly just shows the lock contention
there being with other submits.  And there are a few other bits of
struct_mutex usage in less critical paths (debugfs, etc).  But this
seems like a reasonable step in the right direction.

v2: teach lockdep about shrinker locking patters (danvet) and
    convert to obj->resv locking (danvet)
v3: fix get_vaddr locking for legacy userspace (relocs), devcoredump,
    and rd/hangrd

Rob Clark (23):
  drm/msm: Fix a couple incorrect usages of get_vaddr_active()
  drm/msm/gem: Add obj->lock wrappers
  drm/msm/gem: Rename internal get_iova_locked helper
  drm/msm/gem: Move prototypes to msm_gem.h
  drm/msm/gem: Add some _locked() helpers
  drm/msm/gem: Move locking in shrinker path
  drm/msm/submit: Move copy_from_user ahead of locking bos
  drm/msm: Do rpm get sooner in the submit path
  drm/msm/gem: Switch over to obj->resv for locking
  drm/msm: Use correct drm_gem_object_put() in fail case
  drm/msm: Drop chatty trace
  drm/msm: Move update_fences()
  drm/msm: Add priv->mm_lock to protect active/inactive lists
  drm/msm: Document and rename preempt_lock
  drm/msm: Protect ring->submits with it's own lock
  drm/msm: Refcount submits
  drm/msm: Remove obj->gpu
  drm/msm: Drop struct_mutex from the retire path
  drm/msm: Drop struct_mutex in free_object() path
  drm/msm: Remove msm_gem_free_work
  drm/msm: Drop struct_mutex in madvise path
  drm/msm: Drop struct_mutex in shrinker path
  drm/msm: Don't implicit-sync if only a single ring
