813  *
814  * 64-bit server:
815  *	- SPRG0 scratch for TM recheckpoint/reclaim (reserved for HV on Power4)
816  *	- SPRG2 scratch for exception vectors
817  *	- SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
818  *      - HSPRG0 stores PACA in HV mode
819  *      - HSPRG1 scratch for "HV" exceptions
820  *
821  * 64-bit embedded
822  *	- SPRG0 generic exception scratch
823  *	- SPRG2 TLB exception stack
824  *	- SPRG3 critical exception scratch and
825  *        CPU and NUMA node for VDSO getcpu (user visible)
826  *	- SPRG4 unused (user visible)
827  *	- SPRG6 TLB miss scratch (user visible, sorry !)
828  *	- SPRG7 critical exception scratch
829  *	- SPRG8 machine check exception scratch
830  *	- SPRG9 debug exception scratch
831  *
832  * All 32-bit:
833  *	- SPRG3 current thread_info pointer
834  *        (virtual on BookE, physical on others)
835  *
836  * 32-bit classic:
837  *	- SPRG0 scratch for exception vectors
838  *	- SPRG1 scratch for exception vectors
839  *	- SPRG2 indicator that we are in RTAS
840  *	- SPRG4 (603 only) pseudo TLB LRU data
841  *
842  * 32-bit 40x:
843  *	- SPRG0 scratch for exception vectors
844  *	- SPRG1 scratch for exception vectors
845  *	- SPRG2 scratch for exception vectors

847  *	- SPRG5 scratch for exception vectors (not 403)
848  *	- SPRG6 scratch for exception vectors (not 403)
849  *	- SPRG7 scratch for exception vectors (not 403)
850  *
851  * 32-bit 440 and FSL BookE:
852  *	- SPRG0 scratch for exception vectors
853  *	- SPRG1 scratch for exception vectors (*)
854  *	- SPRG2 scratch for crit interrupts handler
855  *	- SPRG4 scratch for exception vectors

860  *
861  *      Additionally, BookE separates "read" and "write"
862  *      of those registers. That allows to use the userspace
863  *      readable variant for reads, which can avoid a fault
864  *      with KVM type virtualization.
