Oops.
qemu-kvm specific patches which add the cpu_single_env tracking (not polished yet) are here: http://cgit.freedesktop.org/spice/qemu/log/?h=spice.kvm.v28Cannot spot that quickly: In which way are they specific to qemu-kvm?
cpu_single_env bookeeping. But if upstream needs that too having specific patches is pretty pointless. I'll go fix it up upstream then.
cheers, Gerd
