    KVM: arm/arm64: Move timer IRQ map to latest possible time · 41a54482
    Christoffer Dall authored
    We are about to modify the VGIC to allocate all data structures
    dynamically and store mapped IRQ information on a per-IRQ struct, which
    is indeed allocated dynamically at init time.
    
    Therefore, we cannot record the mapped IRQ info from the timer at timer
    reset time like it's done now, because VCPU reset happens before timer
    init.
    
    A possible later time to do this is on the first run of a per VCPU, it
    just requires us to move the enable state to be a per-VCPU state and do
    the lookup of the physical IRQ number when we are about to run the VCPU.
