ARM: perf: updates for 3.19

Hi Arnd, Olof, Russell,

Please can you pull the following ARM perf updates into arm-soc?

I usually send these via rmk's tree, but there's a bunch of CCI PMU rework in here which is then relied upon by other patches in the series, so it would be easiest to keep it all together.

These have been in -next for a few weeks, so please let me know when you've pulled and I'll drop my branch from there.

arm: perf: fold hotplug notifier into arm_pmu (2014-10-30 12:17:01 +0000)

----------------------------------------------------------------
This patch series takes us slightly further on the road to big.LITTLE support in perf. The main change enabling this is moving the CCI PMU driver away from the arm-pmu abstraction, allowing the arch code to focus specifically on support for CPU PMUs.

----------------------------------------------------------------
Mark Rutland (10):
bus: cci: move away from arm_pmu framework
arm: perf: factor out callchain code
arm: perf: add missing pr_info newlines
arm: perf: make PMU probing data-driven
arm: perf: use IDR types for CPU PMUs
arm: perf: limit size of accounting data
arm: perf: kill get_hw_events()
arm: perf: fold percpu_pmu into pmu_hw_events
arm: perf: dynamically allocate cpu hardware data
arm: perf: fold hotplug notifier into arm_pmu

Will Deacon (1):
ARM: perf: use pr_* instead of printk

chai wen (1):
ARM: perf: remove useless return and check of idx in counter handling

Ping? Anything else you need from me to get this into arm-soc?

Pulled into next/drivers. Russell, please yell if you have any objections.
