Changelog: V3: * Remove validity check for 'desc' from accessor function in irqdesc.h . Instead, check the irq 'desc' validity in arm64 pmu driver. V2: * 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.
