Subject: [PATCH 09/27] KVM: PPC: Add PV guest scratch registers
Date: Thu, 1 Jul 2010 12:42:44 +0200 [thread overview]
Message-ID: <1277980982-12433-10-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1277980982-12433-1-git-send-email-agraf@suse.de>
While running in hooked code we need to store register contents out because
we must not clobber any registers.
So let's add some fields to the shared page we can just happily write to.
