[Qemu-devel] Re: [PATCH 1 of 2] kvm: Move KVM mp_state accessors to i386-specific code

[Hollis Blanchard <hollis@penguinppc.org>]

This is the technique Anthony requested this morning, rather than
relocating mp_state. To be honest, I don't care which way it's fixed;
this is at least the 3rd patch to solve this seemingly trivial
problem.

/home/hollisb/source/qemu-fresh.hg/kvm-all.c: In function 'kvm_put_mp_state':
/home/hollisb/source/qemu-fresh.hg/kvm-all.c:212: error: 'struct
CPUPPCState' has no member named 'mp_state'
