This patchset adds support for the Krait CPU PMUs. I split the main patch
up into two parts: first the basic support that gets us just the architected
events and second the full support patch that tackles the PMRESR interface.
Please note, this patchset relies on the per-cpu irq patch from Vinayak Kale,
7f4a8e7b1943 (genirq: Add an accessor for IRQ_PER_CPU flag, 2013-12-04),
that's sitting in linux-next. Patches are based on commit 21dea6695134
(ARM: msm_defconfig: Enable restart driver, 2013-12-20) in linux-next.
Changes since v1:
* Dropped sparse warning patch
* Reworked percpu irq support patch to hide double pointers in dispatch func
* Expanded on comments explaining Krait raw event syntax
* Expanded on DT binding
* Added qcom,no-pc-write property instead of using cpuid scheme
