Why not check for guest_mode instead?
Oh, i forget it...but 'vcpu->guest_mode' is only used in x86 platform,
and make_all_cpus_request() is a common function.
We can have a function kvm_vcpu_guest_mode() that is defined differently
for x86 and the other.
So, maybe it's better use 'vcpu->online' here, and move 'guest_mode' into
'vcpu->arch' ?
I think guest_mode makes sense for the other archs for reducing IPIs, so
let's leave it common and recommend that they implement it. Alex, if
you're ever bored.
