898 * SPRG usage:
899 *
900 * All 64-bit:
901 * - SPRG1 stores PACA pointer except 64-bit server in
902 * HV mode in which case it is HSPRG0
903 *
904 * 64-bit server:
905 * - SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
906 * - SPRG2 scratch for exception vectors
907 * - SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
908 * - HSPRG0 stores PACA in HV mode
909 * - HSPRG1 scratch for "HV" exceptions
910 *
911 * 64-bit embedded
912 * - SPRG0 generic exception scratch
913 * - SPRG2 TLB exception stack
914 * - SPRG3 critical exception scratch (user visible, sorry!)
915 * - SPRG4 unused (user visible)
916 * - SPRG6 TLB miss scratch (user visible, sorry !)
917 * - SPRG7 CPU and NUMA node for VDSO getcpu (user visible)
918 * - SPRG8 machine check exception scratch
919 * - SPRG9 debug exception scratch
920 *
921 * All 32-bit:
922 * - SPRG3 current thread_info pointer
923 * (virtual on BookE, physical on others)
924 *
925 * 32-bit classic:
926 * - SPRG0 scratch for exception vectors
927 * - SPRG1 scratch for exception vectors
928 * - SPRG2 indicator that we are in RTAS
929 * - SPRG4 (603 only) pseudo TLB LRU data
930 *
931 * 32-bit 40x:
932 * - SPRG0 scratch for exception vectors
933 * - SPRG1 scratch for exception vectors
934 * - SPRG2 scratch for exception vectors
935 * - SPRG4 scratch for exception vectors (not 403)
936 * - SPRG5 scratch for exception vectors (not 403)
937 * - SPRG6 scratch for exception vectors (not 403)
938 * - SPRG7 scratch for exception vectors (not 403)
939 *
940 * 32-bit 440 and FSL BookE:
941 * - SPRG0 scratch for exception vectors
942 * - SPRG1 scratch for exception vectors (*)
943 * - SPRG2 scratch for crit interrupts handler
944 * - SPRG4 scratch for exception vectors
945 * - SPRG5 scratch for exception vectors
946 * - SPRG6 scratch for machine check handler
947 * - SPRG7 scratch for exception vectors
948 * - SPRG9 scratch for debug vectors (e500 only)
949 *
950 * Additionally, BookE separates "read" and "write"
951 * of those registers. That allows to use the userspace
952 * readable variant for reads, which can avoid a fault
953 * with KVM type virtualization.
954 *
955 * 32-bit 8xx:
956 * - SPRG0 scratch for exception vectors
