ARM: perf: add support for stalled cycle ABI events
Commit 8f622422 ("perf events: Add generic front-end and back-end stalled cycle event definitions") added two new ABI events for counting stalled cycles. This patch adds support for these new events to the ARM perf implementation. Cc: Jamie Iles <jamie@jamieiles.com> Cc: Jean Pihet <j-pihet@ti.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
