So my reasoning was to not add *every* MSR to that file, especially the
ones which are strictly topical. For example, the MCA MSRs which can
easily live in mce.h as nothing else needs to touch them...

... but ok. I see there could be some merit of keeping them all in the
same place. We can always change that if the handling of msr-index.h
starts becoming too unwieldy.
In any case, we'd need to zap
053080a9d1c8 ("x86/msr: Document msr-index.h rule for addition")
now.
