[PATCH 0/3] Add support for handling IRQs in userspace

[Pavel Fedin <p.fedin@samsung.com>]

This patch series introduces ability to handle IRQs in userspace. This is
currently necessary for ARM KVM in order to be able to use virtual CP15
timer without in-kernel irqchip. This allows to use KVM on machines with
either broken vGIC or custom interrupt controller, like Raspberry Pi 2.

The API is designed to be as much architecture-agnostic is possible.
Currently it actually supports only a single IRQ, but it can be easily
extended to accomodate more.

  KVM: Introduce KVM_EXIT_IRQ
  KVM: Documentation: Document KVM_EXIT_IRQ
  KVM: arm/arm64: Decouple virtual timer from vGIC
