2.6.32-stable review patch. If anyone has any objections, please let us know.


From: Tejun Heo <tj(a)>

commit 0b67c7439fe2a5d76602de36854c88e2beab00b0 upstream.

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.
