Merge tag 'arm-perf-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux into next/cleanup

From Will Deacon:

Bunch of perf updates for the ARM backend that pave the way for
big.LITTLE support in the future. The separation of CPU and PMU code
is also the start of being able to move some of this stuff under
drivers/.

* tag 'arm-perf-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux:
  ARM: perf: move irq registration into pmu implementation
  ARM: perf: move CPU-specific PMU handling code into separate file
  ARM: perf: prepare for moving CPU PMU code into separate file
  ARM: perf: probe devicetree in preference to current CPU
  ARM: perf: remove mysterious compiler barrier
  ARM: pmu: remove arm_pmu_type enumeration
  ARM: pmu: remove unused reservation mechanism
