[PATCH 3/4] powerpc/kvm: Explicitly mark kvm guest code as __init

[Michael Ellerman]

All the code in kvm.c can be marked __init. Most of it is already
inlined into the initcall, but not all. So instead of relying on the
inlining, mark it all as __init. This saves ~280 bytes of text for my
configuration.
