This series seems to assume that Mukesh's hypervisor crash series has been merged, but that's not the case.
I don't see any code context or logical dependency on that series, but correct me if I'm wrong. If there's no
dependency, can you send a v4 based on Linus' tree or hyperv-next to avoid a merge conflict?
