KVM: PPC: Add SVCPU to Book3S_32
We need to keep the pointer to the shadow vcpu somewhere accessible from within really early interrupt code. The best fit I found was the thread struct, as that resides in an SPRG. So let's put a pointer to the shadow vcpu in the thread struct and add an asm-offset so we can find it. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
