From 66bb170655799a0149df0844fb8232f27e54323c Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 16 Apr 2010 00:11:39 +0200 Subject: KVM: PPC: Add fields to shadow vcpu After a lot of thought on how to make the entry / exit code easier, I figured it'd be clever to put even more register state into the shadow vcpu. That way we have more registers available to use, making the code easier to read. So this patch adds a few new fields to that shadow vcpu. Later on we will remove the originals from the vcpu and paca.
