Subject: [PATCH #upstream-fixes] ata_piix: enable 32bit PIO on SATA piix
Date: Mon, 11 Jan 2010 17:03:11 +0900 [thread overview]
Message-ID: <4B4ADB3F.2080505@kernel.org> (raw)
Commit 871af1210f13966ab911ed2166e4ab2ce775b99d enabled 32bit PIO for
PATA piix but didn't for SATA. There's no reason not to use 32bit PIO
on SATA piix. Enable it.
