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.

Changes since v2:
 * Rebased onto v3.14-rc1
 * Fixed problems found by fuzzer (bitmap logic, per-cpu accesses)

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
