Any idea how much it would hurt other targets to have the
__virt_to_phys() and __phys_to_virt() have a 16-bit fixup, even if only
the upper 8 bits are used?

Probably not that much.  But let's make it work satisfactorily for the 
general case first, and then we might consider and test variations that 
could accommodate msm.

Sounds like a good plan.  We've got quite a few other things to clean up
before we can build for more than one arch anyway.
