Subject: [PATCH 3/8] arm: perf: armv7: condense event maps
Date: Tue, 1 Jul 2014 16:11:13 +0100 [thread overview]
Message-ID: <1404227478-9645-4-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1404227478-9645-1-git-send-email-mark.rutland@arm.com>
Now that we have macros for declaring fully invalid event maps, put them
to work for all the ARMv7 PMU event maps. While this necessitates
repeating common indices, we no longer need to refer to *_UNSUPPORTED
events at all, and it makes it possible for the even maps to fit on a
single page on a reasonably sized monitor.
