830 * SPRG usage:
831 *
832 * All 64-bit:
833 *	- SPRG1 stores PACA pointer except 64-bit server in
834 *        HV mode in which case it is HSPRG0
835 *
836 * 64-bit server:
837 *	- SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
838 *	- SPRG2 scratch for exception vectors
839 *	- SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
840 *      - HSPRG0 stores PACA in HV mode
841 *      - HSPRG1 scratch for "HV" exceptions
842 *
843 * 64-bit embedded
844 *	- SPRG0 generic exception scratch
845 *	- SPRG2 TLB exception stack
846 *	- SPRG3 critical exception scratch and
847 *        CPU and NUMA node for VDSO getcpu (user visible)
848 *	- SPRG4 unused (user visible)
849 *	- SPRG6 TLB miss scratch (user visible, sorry !)
850 *	- SPRG7 critical exception scratch
851 *	- SPRG8 machine check exception scratch
852 *	- SPRG9 debug exception scratch
853 *
854 * All 32-bit:
855 *	- SPRG3 current thread_info pointer
856 *        (virtual on BookE, physical on others)
857 *
858 * 32-bit classic:
859 *	- SPRG0 scratch for exception vectors
860 *	- SPRG1 scratch for exception vectors
861 *	- SPRG2 indicator that we are in RTAS
862 *	- SPRG4 (603 only) pseudo TLB LRU data
863 *
864 * 32-bit 40x:
865 *	- SPRG0 scratch for exception vectors
866 *	- SPRG1 scratch for exception vectors
867 *	- SPRG2 scratch for exception vectors
868 *	- SPRG4 scratch for exception vectors (not 403)
869 *	- SPRG5 scratch for exception vectors (not 403)
870 *	- SPRG6 scratch for exception vectors (not 403)
871 *	- SPRG7 scratch for exception vectors (not 403)
872 *
873 * 32-bit 440 and FSL BookE:
874 *	- SPRG0 scratch for exception vectors
875 *	- SPRG1 scratch for exception vectors (*)
876 *	- SPRG2 scratch for crit interrupts handler
877 *	- SPRG4 scratch for exception vectors
878 *	- SPRG5 scratch for exception vectors
879 *	- SPRG6 scratch for machine check handler
880 *	- SPRG7 scratch for exception vectors
881 *	- SPRG9 scratch for debug vectors (e500 only)
882 *
883 *      Additionally, BookE separates "read" and "write"
884 *      of those registers. That allows to use the userspace
885 *      readable variant for reads, which can avoid a fault
886 *      with KVM type virtualization.
887 *
888 *      (*) Under KVM, the host SPRG1 is used to point to
889 *      the current VCPU data structure
890 *
891 * 32-bit 8xx:
892 *	- SPRG0 scratch for exception vectors
893 *	- SPRG1 scratch for exception vectors
894 *	- SPRG2 apparently unused but initialized
