This should fix a performance regression with the internal kernel branch which does not support the upstream I915_MMAP_OFFSET_FIXED. With I915_MMAP_OFFSET_FIXED we defer the mapping flags to the kernel since it knows better where buffers are going to end up (lmem or smem). The internal kernel doesn´t have that and there we should use write combined for anything that can be in lmem.
