1034 * All 64-bit:
1035 * - SPRG1 stores PACA pointer except 64-bit server in
1036 * HV mode in which case it is HSPRG0
1037 *
1038 * 64-bit server:
1039 * - SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
1040 * - SPRG2 scratch for exception vectors
1041 * - SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
1042 * - HSPRG0 stores PACA in HV mode
1043 * - HSPRG1 scratch for "HV" exceptions
1044 *
1045 * 64-bit embedded
1046 * - SPRG0 generic exception scratch
1047 * - SPRG2 TLB exception stack
1048 * - SPRG3 critical exception scratch (user visible, sorry!)
1049 * - SPRG4 unused (user visible)
1050 * - SPRG6 TLB miss scratch (user visible, sorry !)
1051 * - SPRG7 CPU and NUMA node for VDSO getcpu (user visible)
1052 * - SPRG8 machine check exception scratch
1053 * - SPRG9 debug exception scratch
1054 *
1055 * All 32-bit:
1056 * - SPRG3 current thread_info pointer
1057 * (virtual on BookE, physical on others)
1058 *
1059 * 32-bit classic:
1060 * - SPRG0 scratch for exception vectors
1061 * - SPRG1 scratch for exception vectors
1062 * - SPRG2 indicator that we are in RTAS
1063 * - SPRG4 (603 only) pseudo TLB LRU data
1064 *
1065 * 32-bit 40x:
1066 * - SPRG0 scratch for exception vectors
1067 * - SPRG1 scratch for exception vectors
1068 * - SPRG2 scratch for exception vectors
1069 * - SPRG4 scratch for exception vectors (not 403)
1070 * - SPRG5 scratch for exception vectors (not 403)
1071 * - SPRG6 scratch for exception vectors (not 403)
1072 * - SPRG7 scratch for exception vectors (not 403)
1073 *
1074 * 32-bit 440 and FSL BookE:
1075 * - SPRG0 scratch for exception vectors
1076 * - SPRG1 scratch for exception vectors (*)
1077 * - SPRG2 scratch for crit interrupts handler
1078 * - SPRG4 scratch for exception vectors

1080 * - SPRG6 scratch for machine check handler
1081 * - SPRG7 scratch for exception vectors
1082 * - SPRG9 scratch for debug vectors (e500 only)
1083 *
1084 * Additionally, BookE separates "read" and "write"
1085 * of those registers. That allows to use the userspace
1086 * readable variant for reads, which can avoid a fault
1087 * with KVM type virtualization.
1088 *
