1075 * SPRG usage:
1076 *
1077 * All 64-bit:
1078 *	- SPRG1 stores PACA pointer except 64-bit server in
1079 *        HV mode in which case it is HSPRG0
1080 *
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
1097 *
1098 * All 32-bit:
1099 *	- SPRG3 current thread_struct physical addr pointer
1100 *        (virtual on BookE, physical on others)
1101 *
1102 * 32-bit classic:
1103 *	- SPRG0 scratch for exception vectors
1104 *	- SPRG1 scratch for exception vectors
1105 *	- SPRG2 indicator that we are in RTAS
1106 *	- SPRG4 (603 only) pseudo TLB LRU data
1107 *
1108 * 32-bit 40x:
1109 *	- SPRG0 scratch for exception vectors
1110 *	- SPRG1 scratch for exception vectors
1111 *	- SPRG2 scratch for exception vectors
1112 *	- SPRG4 scratch for exception vectors (not 403)
1113 *	- SPRG5 scratch for exception vectors (not 403)
1114 *	- SPRG6 scratch for exception vectors (not 403)
1115 *	- SPRG7 scratch for exception vectors (not 403)
1116 *
1117 * 32-bit 440 and FSL BookE:
1118 *	- SPRG0 scratch for exception vectors
1119 *	- SPRG1 scratch for exception vectors (*)
1120 *	- SPRG2 scratch for crit interrupts handler
1121 *	- SPRG4 scratch for exception vectors
1122 *	- SPRG5 scratch for exception vectors
1123 *	- SPRG6 scratch for machine check handler
1124 *	- SPRG7 scratch for exception vectors
1125 *	- SPRG9 scratch for debug vectors (e500 only)
1126 *
1127 *      Additionally, BookE separates "read" and "write"
1128 *      of those registers. That allows to use the userspace
1129 *      readable variant for reads, which can avoid a fault
1130 *      with KVM type virtualization.
1131 *
1132 * 32-bit 8xx:
1133 *	- SPRG0 scratch for exception vectors
1134 *	- SPRG1 scratch for exception vectors
