 950 * SPRG usage:
 951 *
 952 * All 64-bit:
 953 *      - SPRG1 stores PACA pointer except 64-bit server in
 954 *        HV mode in which case it is HSPRG0
 955 *
 956 * 64-bit server:
 957 *      - SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
 958 *      - SPRG2 scratch for exception vectors
 959 *      - SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
 960 *      - HSPRG0 stores PACA in HV mode
 961 *      - HSPRG1 scratch for "HV" exceptions
 962 *
 963 * 64-bit embedded
 964 *      - SPRG0 generic exception scratch
 965 *      - SPRG2 TLB exception stack
 966 *      - SPRG3 critical exception scratch (user visible, sorry!)
 967 *      - SPRG4 unused (user visible)
 968 *      - SPRG6 TLB miss scratch (user visible, sorry !)
 969 *      - SPRG7 CPU and NUMA node for VDSO getcpu (user visible)
 970 *      - SPRG8 machine check exception scratch
 971 *      - SPRG9 debug exception scratch
 972 *
 973 * All 32-bit:
 974 *      - SPRG3 current thread_info pointer
 975 *        (virtual on BookE, physical on others)
 976 *
 977 * 32-bit classic:
 978 *      - SPRG0 scratch for exception vectors
 979 *      - SPRG1 scratch for exception vectors
 980 *      - SPRG2 indicator that we are in RTAS
 981 *      - SPRG4 (603 only) pseudo TLB LRU data
 982 *
 983 * 32-bit 40x:
 984 *      - SPRG0 scratch for exception vectors
 985 *      - SPRG1 scratch for exception vectors
 986 *      - SPRG2 scratch for exception vectors
 987 *      - SPRG4 scratch for exception vectors (not 403)
 988 *      - SPRG5 scratch for exception vectors (not 403)
 989 *      - SPRG6 scratch for exception vectors (not 403)
 990 *      - SPRG7 scratch for exception vectors (not 403)
 991 *
 992 * 32-bit 440 and FSL BookE:
 993 *      - SPRG0 scratch for exception vectors
 994 *      - SPRG1 scratch for exception vectors (*)
 995 *      - SPRG2 scratch for crit interrupts handler
 996 *      - SPRG4 scratch for exception vectors
 997 *      - SPRG5 scratch for exception vectors
 998 *      - SPRG6 scratch for machine check handler
 999 *      - SPRG7 scratch for exception vectors
1000 *      - SPRG9 scratch for debug vectors (e500 only)
1001 *
1002 *      Additionally, BookE separates "read" and "write"
1003 *      of those registers. That allows to use the userspace
1004 *      readable variant for reads, which can avoid a fault
1005 *      with KVM type virtualization.
1006 *
1007 * 32-bit 8xx:
1008 *      - SPRG0 scratch for exception vectors
1009 *      - SPRG1 scratch for exception vectors
1010 *      - SPRG2 scratch for exception vectors
