Hi Alex,
Seems like you accidentally sent out two copies of this patch, hopefully
I'm reviewing the right one...

Review comments from v1 that used kvm_emulate_wbinvd() pointed out that
kvm_emulate_* was inconsistant in using skipping, while kvm_emulate() always
skips. The first patch cleans up the existing use while the second patch

Thanks, applied.
Currently kvm_emulate() skips the instruction but kvm_emulate_* sometimes
don't. The end reult is the caller ends up doing the skip themselves.
Let's make them consistant.
