Yeah, let's drop patch 7 and just use bits for now. I think using
KVM_ARCH_REQ_FLAGS directly should be fine, especially after the default
is flipped from "no wakeup" to "wakeup", but for 4.12 this is the
simplest incremental step.

I'm renaming this to kvm_request_needs_ipi; the point of the IPI for
synchronous requests is not the "kick", but the "ack" that comes back.
