This patch series adds support to handle interrupt registration/deregistration in arm64 pmu driver when pmu interrupt type is percpu.
Changelog: V7: * In arm64 pmu driver: Instead of passing 'struct arm_pmu' pointer, pass the irq number directly to armpmu_[enable/disable]_percpu_irq(). Clean-up the percpu active irq cpumask set/clear. V6: * In arm64 pmu driver: Use macro 'IRQ_TYPE_NONE' while passing irq type value to enable_percpu_irq(). Change 'irqs' etc variables as unsigned, modify the check for 'irqs' inside armpmu_[release/reserve]_hardware(). V5: * In irqdesc.h: Added Chris Smith's sign-off. In arm64 pmu driver: Handle the invalid irq-0 case for platform_get_irq(). V4: * In arm64 pmu driver: Avoid using irq_to_desc() to check validity of irq. 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.
