[PATCH v3 00/25] powerpc/64s interrupt handler cleanups, gasification

[Nicholas Piggin]

One more try at this, sorry for the spam. To reduce the chance of more
problems I've gone back the other way and actually pulled out almost
all the patches that altered generated code, leaving just a couple of
simple cases.

Thanks,
Nick
