Subject: i915 needs pgprot_writecombine() and is_io_mapping_posible()

A recent (probably within the last week) commit seems to have caused
the i915 driver to need to use two unexported symbols:

ERROR: "pgprot_writecombine" [drivers/gpu/drm/i915/i915.ko] undefined!
ERROR: "is_io_mapping_possible" [drivers/gpu/drm/i915/i915.ko] undefined!

Is the right fix just to export them?  

Thanks,

							- Ted
