powerpc/perf: Add stalled-cycles events
Support for stalled-cycles-frontend and stalled-cycles-backend is added for e500-based processors. The following mappings are used: stalled-cycles-frontend or idle-cycles-frontend: Com:18 Cycles decode stalled stalled-cycles-backend or idle-cycles-backend Com:19 cycles issue stalled Signed-off-by: Chris Freehill <chrisf@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
