ARM: perf: add format entry to describe event -> config mapping It's all very well providing an events directory to userspace that details our events in terms of "event=0xNN", but if we don't define how to encode the "event" field in the perf attr.config, then it's a waste of time. This patch adds a single format entry to describe that the event field occupies the bottom 8 bits of our config field on ARMv7. Signed-off-by: Will Deacon <will.deacon@arm.com>
