903  *
904  * 64-bit server:
905  *	- SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
906  *	- SPRG2 scratch for exception vectors
907  *	- SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
908  *      - HSPRG0 stores PACA in HV mode
909  *      - HSPRG1 scratch for "HV" exceptions
910  *
911  * 64-bit embedded
912  *	- SPRG0 generic exception scratch
913  *	- SPRG2 TLB exception stack
914  *	- SPRG3 critical exception scratch (user visible, sorry!)
915  *	- SPRG4 unused (user visible)
916  *	- SPRG6 TLB miss scratch (user visible, sorry !)
917  *	- SPRG7 CPU and NUMA node for VDSO getcpu (user visible)
918  *	- SPRG8 machine check exception scratch
919  *	- SPRG9 debug exception scratch
920  *
921  * All 32-bit:
922  *	- SPRG3 current thread_info pointer
923  *        (virtual on BookE, physical on others)
924  *
925  * 32-bit classic:
926  *	- SPRG0 scratch for exception vectors
927  *	- SPRG1 scratch for exception vectors
928  *	- SPRG2 indicator that we are in RTAS
929  *	- SPRG4 (603 only) pseudo TLB LRU data
930  *
931  * 32-bit 40x:
932  *	- SPRG0 scratch for exception vectors
933  *	- SPRG1 scratch for exception vectors
934  *	- SPRG2 scratch for exception vectors

937  *	- SPRG6 scratch for exception vectors (not 403)
938  *	- SPRG7 scratch for exception vectors (not 403)
939  *
940  * 32-bit 440 and FSL BookE:
941  *	- SPRG0 scratch for exception vectors
942  *	- SPRG1 scratch for exception vectors (*)
943  *	- SPRG2 scratch for crit interrupts handler

951  *      of those registers. That allows to use the userspace
952  *      readable variant for reads, which can avoid a fault
953  *      with KVM type virtualization.
