Hi,

the following patches are from the PREEMPT_RT queue. It is mostly about
disabling interrupts/preemption which leads to problems.
Unfortunately DRM_I915_LOW_LEVEL_TRACEPOINTS had to be disabled because
it acquires locks from within trace points.
I tested it on a SandyBridge with built-in i915 by using X, OpenGL and
playing videos without noticing any warnings. However, some code paths
were not entered.
