KVM: PPC: BookE: Add GET/SET_ONE_REG interface for VRSAVE
This makes the VRSAVE register value for a vcpu accessible through the GET/SET_ONE_REG interface on Book E systems (in addition to the existing GET/SET_SREGS interface), for consistency with Book 3S. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>
