Done.

Imo i915_ums.c is a dungeon and I don't want to change anything in there
if at all possible. Hence why I've kept the old names.

I don't mind too much if something in the dungeons (i915_ums.c and
i915_dma.c overflows). Same for reg defines, since usually you don't
really read them that often. Real code in source files shouldn't overflow
for easier reading (with some exceptions for strings).
