1087 *
1088 * All 64-bit:
1089 *	- SPRG1 stores PACA pointer except 64-bit server in
1090 *        HV mode in which case it is HSPRG0
1091 *
1092 * 64-bit server:
1093 *	- SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
1094 *	- SPRG2 scratch for exception vectors
1095 *	- SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
1096 *      - HSPRG0 stores PACA in HV mode
1097 *      - HSPRG1 scratch for "HV" exceptions
1098 *
1099 * 64-bit embedded
1100 *	- SPRG0 generic exception scratch
1101 *	- SPRG2 TLB exception stack
1102 *	- SPRG3 critical exception scratch (user visible, sorry!)
1103 *	- SPRG4 unused (user visible)
1104 *	- SPRG6 TLB miss scratch (user visible, sorry !)
1105 *	- SPRG7 CPU and NUMA node for VDSO getcpu (user visible)
1106 *	- SPRG8 machine check exception scratch
1107 *	- SPRG9 debug exception scratch
1108 *
1109 * All 32-bit:
1110 *	- SPRG3 current thread_struct physical addr pointer
1111 *        (virtual on BookE, physical on others)
1112 *
1113 * 32-bit classic:
1114 *	- SPRG0 scratch for exception vectors
1115 *	- SPRG1 scratch for exception vectors
1116 *	- SPRG2 indicator that we are in RTAS
1117 *	- SPRG4 (603 only) pseudo TLB LRU data
1118 *
1119 * 32-bit 40x:
1120 *	- SPRG0 scratch for exception vectors
1121 *	- SPRG1 scratch for exception vectors
1122 *	- SPRG2 scratch for exception vectors
1123 *	- SPRG4 scratch for exception vectors (not 403)
1124 *	- SPRG5 scratch for exception vectors (not 403)
1125 *	- SPRG6 scratch for exception vectors (not 403)
1126 *	- SPRG7 scratch for exception vectors (not 403)
1127 *
1128 * 32-bit 440 and FSL BookE:
1129 *	- SPRG0 scratch for exception vectors
1130 *	- SPRG1 scratch for exception vectors (*)
1131 *	- SPRG2 scratch for crit interrupts handler
1132 *	- SPRG4 scratch for exception vectors
1133 *	- SPRG5 scratch for exception vectors
1134 *	- SPRG6 scratch for machine check handler
1135 *	- SPRG7 scratch for exception vectors
1136 *	- SPRG9 scratch for debug vectors (e500 only)
1137 *
1138 *      Additionally, BookE separates "read" and "write"
1139 *      of those registers. That allows to use the userspace
1140 *      readable variant for reads, which can avoid a fault
1141 *      with KVM type virtualization.
1142 *
1143 * 32-bit 8xx:
