1081  * 64-bit server:
1082  *	- SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
1083  *	- SPRG2 scratch for exception vectors
1084  *	- SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
1085  *      - HSPRG0 stores PACA in HV mode
1086  *      - HSPRG1 scratch for "HV" exceptions
1087  *
1088  * 64-bit embedded
1089  *	- SPRG0 generic exception scratch
1090  *	- SPRG2 TLB exception stack
1091  *	- SPRG3 critical exception scratch (user visible, sorry!)
1092  *	- SPRG4 unused (user visible)
1093  *	- SPRG6 TLB miss scratch (user visible, sorry !)
1094  *	- SPRG7 CPU and NUMA node for VDSO getcpu (user visible)
1095  *	- SPRG8 machine check exception scratch
1096  *	- SPRG9 debug exception scratch

1098  * All 32-bit:

1100  *        (virtual on BookE, physical on others)
1101  *
1102  * 32-bit classic:
1103  *	- SPRG0 scratch for exception vectors

1105  *	- SPRG2 indicator that we are in RTAS
1106  *	- SPRG4 (603 only) pseudo TLB LRU data

1115  *	- SPRG7 scratch for exception vectors (not 403)
