Subject: [PATCH V2 0/2] genirq: arm64: perf: support for percpu pmu interrupt

This patch series adds support to handle interrupt registration/deregistration
in arm64 pmu driver when pmu interrupt type is percpu.

Changes since V1:
* To determine whether an IRQ is percpu or not, added an accessor function in
  irqdesc.h . This approach was used by Chris Smith here[1] for similar changes
  in arm pmu driver.
* In arm64 pmu driver: Got rid of unnecessary pointer typecastings.
