Merge tag 'drm-intel-fixes-2015-07-15' of git://anongit.freedesktop.org/drm-intel into drm-fixes 

Next batch of i915 fixes. Note that the compat32 patch here needs the drm
core one to be actually useful, I'll send you that one with a separate
drm-fixes pull request. One revert because a fix in -rc2 did break
existing userspace.

* tag 'drm-intel-fixes-2015-07-15' of git://anongit.freedesktop.org/drm-intel:
  drm/i915: Do not call intel_crtc_disable if the crtc is already disabled.
  Revert "drm/i915: Declare the swizzling unknown for L-shaped configurations"
  drm/i915: Forward all core DRM ioctls to core compat handling
  drm/i915: fix oops in primary_check_plane
  drm/i915: remove unused has_dma_mapping flag
  drm/i915: Fix missing return warning for !CONFIG_DEBUGFS
  drm/i915: avoid leaking DMA mappings
  drm/i915: Snapshot seqno of most recently submitted request.
  drm/i915: Store device pointer in contexts for late tracepoint usafe
