Subject: [PATCH 2/2] KVM: PPC: BookE: Add MCSR SPR support
Date: Mon, 13 Aug 2012 15:21:57 +0200	[thread overview]
Message-ID: <1344864117-14654-3-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1344864117-14654-1-git-send-email-agraf@suse.de>

Add support for the MCSR SPR. This only implements the SPR storage
bits, not actual machine checks.
