What about __gem_mmap__wc? Also shouldn't we just fix the __gem_mmap_offset
fallback in __gem_mmap and that will take care of both __gem_mmap__cpu and
__gem_mmap__wc?

(I think it will actually also fix __gem_mmap__device_coherent and
__gem_mmap__cpu_coherent but maybe we can still have those patches in this
series especially if they save a couple of system calls).
