The path of least resistance is likely to get acks for the x86 and sgx changes,
and let Paolo take it through the KVM tree.  The KVM changes are much more
likely to have non-trivial conflicts, e.g. making exit_reason a union touches a
ton of code; getting and carrying acked-by for those will be tough sledding.
