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

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

From: Stephane Eranian <eranian(a)google.com>

commit d11007703c31db534674ebeeb9eb047bbbe758bd upstream.

Based on Intel Vol3b (March 2010), the event
SNOOPQ_REQUEST_OUTSTANDING is restricted to counters 0,1 so
update the event table for Intel Westmere accordingly.
