Marc Zyngier ac0899da0e KVM: arm64: Don't read a HW interrupt pending state in user context ... commit 2cdea19a34 upstream. Since 5bfa685e62 ("KVM: arm64: vgic: Read HW interrupt pending state from the HW"), we're able to source the pending bit for an interrupt that is stored either on the physical distributor or on a device. However, this state is only available when the vcpu is loaded, and is not intended to be accessed from userspace. Unfortunately, the GICv2 emulation doesn't provide specific userspace accessors, and we fallback with the ones that are intended for the guest, with fatal consequences. Add a new vgic_uaccess_read_pending() accessor for userspace to use, build on top of the existing vgic_mmio_read_pending().
