linux-next: manual merge of the drm tree

Hi Dave,

Today's linux-next merge of the drm tree got a conflict in include/Kbuild
between commit 4896a02e1e6d4f0ae5b23c24eff0ba10e26caab4 ("kbuild: only
one call for include/ in make headers_*") from the kbuild tree and commit
ae74c0f7f4abab0cf1e943c562b52df8868dc1ee ("drm: reorganise drm tree to be
more future proof") from the drm tree.

The former removes a line just where the latter is adding one. I fixed it
up and can carry the fix.

Today's linux-next merge of the drm tree got conflicts in

caused by commits e1264eb (Revert "drm/i915: Delay disabling of VGA memory
until vgacon->fbcon handoff is done"), 20ddf66 (drm/i915: Make
intel_crtc_active() available outside intel_pm.c), 18442d0 (drm/i915: Fix

I fixed them up (see below). Please verify that the resolution looks good.

linux-next: manual merge of the drm tree

[Stephen Rothwell]

Hi Dave,

Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/i915/i915_dma.c between commit
80a914dc05683ecfc98f9e1887fd6564846ffbec ("misc: replace __FUNCTION__
with __func__") from Linus' tree and commit
811c552c21f3d7fca8eb647ccf0d303378ccea7d ("i915: Use struct_mutex to
protect ring in GEM mode") from the drm tree.

Just context changes.  I fixed it up (see below).
