Subject: [PATCH 0/2] perf_events: correct event assignments on Intel processors

	This series of patches corrects the assignment of events to counters
	for the Intel X86 processors.

	Not all events can be measured on any counter. Not all filters can
	be used on fixed counters.

	The current implementation silently returns bogus counts in case the
	event is programmed into the wrong counter.

	Signed-off-by: Stephane Eranian <eranian@...il.com>
