From: Greg KH
Date: Tue Feb 15 2011 - 20:41:44 EST


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

------------------

From: Felix Beck <felix.beck@xxxxxxxxxx>

commit 53ec24b1e6c7118a127cf029a1519a2ce55268ec upstream.

Fix the check for ap interupts to look for facility bits 2 and 65.
Make sure that we only register interrupts for aps, if the machine
has ap interrupt support.

This patch is relevant only for the 2.6.37 stable series.
