KVM: arm64: vgic-v3: Take cpu_if pointer directly instead of vcpu
If we move the used_lrs field to the version-specific cpu interface structure, the following functions only operate on the struct vgic_v3_cpu_if and not the full vcpu: __vgic_v3_save_state __vgic_v3_restore_state __vgic_v3_activate_traps __vgic_v3_deactivate_traps __vgic_v3_save_aprs __vgic_v3_restore_aprs This is going to be very useful for nested virt, so move the used_lrs field and change the prototypes and implementations of these functions to take the cpu_if parameter directly. No functional change. Reviewed-by: James Morse <james.morse@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org>
