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.

This patch adds an accessor function for IRQ_PER_CPU flag.
The accessor function is useful to dertermine whether an IRQ is percpu or not.

I don't think it is worth checking for the validity of "desc" here. All
the other accessors assume that you've not passed a stupid "irq" value.
Simply having
return !!(desc->status_use_accessors & IRQ_PER_CPU);
should be enough.

hmm..Okay, will remove the 'desc' validity check from here.
