These two patches fix two separate issues with the architected timer and the corresponding interrupt injection to VMs on KVM/ARM. The first patch fixes an issue introduced with the active timer state switching series recently merged for v4.3, which could cause a guest to loop without progress if another VCPU is run on the same physical CPU and preempts the original VCPU while the guest is running the ISR for the timer interrupt. The second patch resets the architected timer's control register to zero on system reset, ensuring that interrupts are not injected when a system resets. This fixes a long-standing issue with UEFI, where soft reset initiated from within UEFI prevented the system from booting again.
