Subject: [PATCH 01/10] ARM: perf: de-const struct arm_pmu
Date: Mon,  8 Aug 2011 18:16:02 +0100	[thread overview]
Message-ID: <1312823771-9952-2-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1312823771-9952-1-git-send-email-will.deacon@arm.com>

From: Mark Rutland <mark.rutland@arm.com>

This patch removes const qualifiers from instances of struct arm_pmu,
and functions initialising them, in preparation for generalising
arm_pmu usage to system (AKA uncore) PMUs.

This will allow for dynamically modifiable structures (locks,
struct pmu) to be added as members of struct arm_pmu.
