Subject: [Qemu-devel] [PATCH 1/4] ppc-40x: Get TLB attributes from TLBLO.
Date: Mon, 11 Jan 2010 15:49:48 +0100	[thread overview]
Message-ID: <1263221391-3642-2-git-send-email-edgar.iglesias@gmail.com> (raw)
In-Reply-To: <1263221391-3642-1-git-send-email-edgar.iglesias@gmail.com>

The ZSEL was incorrectly beeing decoded from TLBHI. Decode it from
TLBLO instead.
