On looking at this further, I was able to figure out the parts on
ppc64 utilizing KVM and enabled them dependent on CONFIG_KVM being
enabled. I tested this with a ppc64 allnoconfig and it built
succesfully (depending on a unrelated patch to enable printk for
powernv).

I've sent the patch but it still seems that we will be playing
whack-a-mole for now with code which uses KVM indepedent of
CONFIG_KVM. May be fixing it incrementally is a better option than
lumping all these together?
