ARM: 5899/2: arm: provide a mechanism to reserve performance counters
To add support for perf events and to allow the hardware counters to be shared with oprofile, we need a way to reserve access to the pmu (performance monitor unit). Platforms with PMU interrupts should register the interrupts in arch/arm/kernel/pmu.c Signed-off-by: Jamie Iles <jamie.iles@picochip.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
