Subject: [Qemu-devel] [PATCH 5/8] PPC: booke206: allow NULL raddr in ppcmas_tlb_check
Date: Sat, 21 Jan 2012 05:15:27 +0100	[thread overview]
Message-ID: <1327119330-29304-6-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1327119330-29304-1-git-send-email-agraf@suse.de>

We might want to call the tlb check function without actually caring about
the real address resolution. Check if we really should write the value
back.
