Subject: [PATCH v2 0/7] Support Krait CPU PMUs

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
