KVM: PPC: booke(hv): Fix save/restore of guest accessible SPRGs.
For Guest accessible SPRGs 4-7, save/restore must be handled differently for 64bit and non-64 bit case. Use the PPC_STD/PPC_LD macros for saving/restoring to/from these registers. Signed-off-by: Varun Sethi <Varun.Sethi@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
