(Joey) Patches 1 and 2 move the GICv5 CPU interface save/restore and the stage-2 flushes into the band the dispatcher rejects once pKVM has finalised, since the host has no use for them in protected mode. Patch 3 validates the vgic model EL2 copies from the host. Patch 4 stops nVHE from accessing the GICv5 CPU interface from EL1, and patch 5 fixes two stale comments. The GICv5 residency and VDPEND hypercalls in kvmarm/next still check for pKVM in each handler. I'll move them into the same band once this lands. Based on Linux 7.3-rc3 (fd73f4a665989). On kvmarm/next, patches 1 and 2 have a minor conflict: new hypercall IDs sit next to the ones they move.
