The names are Linux-defined. The values are IVOR numbers.

Yes, it's asm/kvm_asm.h at the moment.
It's actually BOOKE_INTERRUPT_MACHINE_CHECK, etc. The exception macros
paste on BOOKE_INTERRUPT_ when they use it, to keep the macro users from
having to wrap lines even more often.

Yes, that was one of the things I had been planning to fix post-RFC.
Any preference what header it should be in? asm/reg_booke.h seems to be
the least bad option of the existing headers -- or perhaps move
head_booke.h to arch/powerpc/include/asm.
Long-term it would also be nice for this to replace, rather than
supplement, the current numbers, though as Ben pointed out there are a
number of places throughout the code that will have to be fixed for that
to happen.
