[PATCH v2 0/4] KVM: arm64: Don't perform vgic-v2 lazy init on timer injection

[Marc Zyngier <maz@kernel.org>]

This is the second version of this series aiming at fixing issues
with vgic-v2 being initialised from non-preemptible context.

* From v1 [1]:

  - Repaint kvm_timer_irq_can_fire() to kvm_timer_enabled()

  - Drop duplicate kvm_timer_update_status() call

  - Force lazy init on the irqfd slow-path for SPIs
