1042 *
1043 * All 64-bit:
1044 * - SPRG1 stores PACA pointer except 64-bit server in
1045 * HV mode in which case it is HSPRG0
1046 *
1047 * 64-bit server:
1048 * - SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
1049 * - SPRG2 scratch for exception vectors
1050 * - SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
1051 * - HSPRG0 stores PACA in HV mode
1052 * - HSPRG1 scratch for "HV" exceptions
1053 *
1054 * 64-bit embedded
1055 * - SPRG0 generic exception scratch
1056 * - SPRG2 TLB exception stack
1057 * - SPRG3 critical exception scratch (user visible, sorry!)
1058 * - SPRG4 unused (user visible)
1059 * - SPRG6 TLB miss scratch (user visible, sorry !)
1060 * - SPRG7 CPU and NUMA node for VDSO getcpu (user visible)
1061 * - SPRG8 machine check exception scratch
1062 * - SPRG9 debug exception scratch
1063 *
1064 * All 32-bit:
1065 * - SPRG3 current thread_struct physical addr pointer
1066 * (virtual on BookE, physical on others)
1067 *
1068 * 32-bit classic:
1069 * - SPRG0 scratch for exception vectors
1070 * - SPRG1 scratch for exception vectors
1071 * - SPRG2 indicator that we are in RTAS
1072 * - SPRG4 (603 only) pseudo TLB LRU data
1073 *
1074 * 32-bit 40x:
1075 * - SPRG0 scratch for exception vectors
1076 * - SPRG1 scratch for exception vectors
1077 * - SPRG2 scratch for exception vectors
1078 * - SPRG4 scratch for exception vectors (not 403)
1079 * - SPRG5 scratch for exception vectors (not 403)
1080 * - SPRG6 scratch for exception vectors (not 403)
1081 * - SPRG7 scratch for exception vectors (not 403)
1082 *
1083 * 32-bit 440 and FSL BookE:
1084 * - SPRG0 scratch for exception vectors
1085 * - SPRG1 scratch for exception vectors (*)
1086 * - SPRG2 scratch for crit interrupts handler
1087 * - SPRG4 scratch for exception vectors
1088 * - SPRG5 scratch for exception vectors
1089 * - SPRG6 scratch for machine check handler
1090 * - SPRG7 scratch for exception vectors
1091 * - SPRG9 scratch for debug vectors (e500 only)
1092 *
1093 * Additionally, BookE separates "read" and "write"
1094 * of those registers. That allows to use the userspace
1095 * readable variant for reads, which can avoid a fault
1096 * with KVM type virtualization.
1097 *
1098 * 32-bit 8xx:
1099 * - SPRG0 scratch for exception vectors
