Merge commit drm-intel-fixes into topic/ppgtt

I need the tricky do_switch fix before I can merge the final piece of
the ppgtt enabling puzzle. Otherwise the conflict will be a real pain
to resolve since the do_switch hunk from -fixes must be placed at the
exact right place within a hunk in the next patch.

Conflicts:
	drivers/gpu/drm/i915/i915_gem_context.c
	drivers/gpu/drm/i915/i915_gem_execbuffer.c
