Merge remote branch 'anholt/drm-intel-next' into drm-linus
This merges the upstream Intel tree and fixes up numerous conflicts due to patches merged into Linus tree later in -rc cycle. Conflicts: drivers/char/agp/intel-agp.c drivers/gpu/drm/drm_dp_i2c_helper.c drivers/gpu/drm/i915/i915_irq.c drivers/gpu/drm/i915/i915_suspend.c
