815 * SPRG usage:
816 *
817 * All 64-bit:
818 *	- SPRG1 stores PACA pointer except 64-bit server in
819 *        HV mode in which case it is HSPRG0
820 *
821 * 64-bit server:
822 *	- SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
823 *	- SPRG2 scratch for exception vectors
824 *	- SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
825 *      - HSPRG0 stores PACA in HV mode
826 *      - HSPRG1 scratch for "HV" exceptions
827 *
828 * 64-bit embedded
829 *	- SPRG0 generic exception scratch
830 *	- SPRG2 TLB exception stack
831 *	- SPRG3 critical exception scratch and
832 *        CPU and NUMA node for VDSO getcpu (user visible)
833 *	- SPRG4 unused (user visible)
834 *	- SPRG6 TLB miss scratch (user visible, sorry !)
835 *	- SPRG7 critical exception scratch
836 *	- SPRG8 machine check exception scratch
837 *	- SPRG9 debug exception scratch
838 *
839 * All 32-bit:
840 *	- SPRG3 current thread_info pointer
841 *        (virtual on BookE, physical on others)
842 *
843 * 32-bit classic:
844 *	- SPRG0 scratch for exception vectors
845 *	- SPRG1 scratch for exception vectors
846 *	- SPRG2 indicator that we are in RTAS
847 *	- SPRG4 (603 only) pseudo TLB LRU data
848 *
849 * 32-bit 40x:
850 *	- SPRG0 scratch for exception vectors
851 *	- SPRG1 scratch for exception vectors
852 *	- SPRG2 scratch for exception vectors
853 *	- SPRG4 scratch for exception vectors (not 403)
854 *	- SPRG5 scratch for exception vectors (not 403)
855 *	- SPRG6 scratch for exception vectors (not 403)
856 *	- SPRG7 scratch for exception vectors (not 403)
857 *
858 * 32-bit 440 and FSL BookE:
859 *	- SPRG0 scratch for exception vectors
860 *	- SPRG1 scratch for exception vectors (*)
861 *	- SPRG2 scratch for crit interrupts handler
862 *	- SPRG4 scratch for exception vectors
863 *	- SPRG5 scratch for exception vectors
864 *	- SPRG6 scratch for machine check handler
865 *	- SPRG7 scratch for exception vectors
866 *	- SPRG9 scratch for debug vectors (e500 only)
867 *
868 *      Additionally, BookE separates "read" and "write"
869 *      of those registers. That allows to use the userspace
870 *      readable variant for reads, which can avoid a fault
871 *      with KVM type virtualization.
872 *
873 *      (*) Under KVM, the host SPRG1 is used to point to
874 *      the current VCPU data structure
875 *
876 * 32-bit 8xx:
877 *	- SPRG0 scratch for exception vectors
878 *	- SPRG1 scratch for exception vectors
879 *	- SPRG2 apparently unused but initialized
