[Qemu-devel] [PATCH] PPC: Sync CPU state for KVM

[Alexander Graf <agraf@suse.de>]

Some recent change made PPC guests always start at address 0x0 because env
isn't synced to kvm_state on first bootup.

I'm not sure if this is the correct bugfix, but at least it makes PPC boot
again with KVM enabled.
