Subject: [PATCH 08/14] KVM: PPC: Stub emulate CFAR and PURR SPRs
Date: Thu, 25 Aug 2011 16:39:47 +0200	[thread overview]
Message-ID: <1314283193-10323-9-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1314283193-10323-1-git-send-email-agraf@suse.de>

Recent Linux versions use the CFAR and PURR SPRs, but don't really care about
their contents (yet). So for now, we can simply return 0 when the guest wants
to read them.
