Marc Zyngier 163b489325 KVM: arm: vgic: Synchronize the whole guest on GIC{D,R}_I{S,C}ACTIVER read ... [ Upstream commit 9a50ebbffa ] When a guest tries to read the active state of its interrupts, we currently just return whatever state we have in memory. This means that if such an interrupt lives in a List Register on another CPU, we fail to obsertve the latest active state for this interrupt. In order to remedy this, stop all the other vcpus so that they exit and we can observe the most recent value for the state. This is similar to what we are doing for the write side of the same registers, and results in new MMIO handlers for userspace (which do not need to stop the guest, as it is supposed to be stopped already).
