[PATCH 0/8] FBC (+stolen) locking, v5

[Paulo Zanoni <przanoni@gmail.com>]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

The big difference in this series is the fact that stolen_lock got
much simpler. I was previously afraid of doing the CFB release and
realloc operations in a non-atomic way, but I redebugged things and
realized that, after we fixed the CFB size checks, we're not trying to
free+allocate the CFB with FBC enabled, so we can make stolen_lock
become much simpler.

Thanks Chris for the suggestions and reviews!

Paulo Zanoni (8):
  drm/i915: add simple wrappers for stolen node insertion/removal
  drm/i915: move FBC code out of i915_gem_stolen.c
  drm/i915: add dev_priv->mm.stolen_lock
  drm/i915: add the FBC mutex
  drm/i915: intel_frontbuffer_flip_prepare() doesn't need struct_mutex
  drm/i915: intel_unregister_dsm_handler() doesn't need struct_mutex
  drm/i915: FBC doesn't need struct_mutex anymore
  drm/i915: protect FBC functions with HAS_FBC checks
