761  *
762  * 64-bit server:

765  * - SPRG3 CPU and NUMA node for VDSO getcpu (user visible)
766  * - HSPRG0 stores PACA in HV mode
767  * - HSPRG1 scratch for "HV" exceptions
768  *
769  * 64-bit embedded
770  * - SPRG0 generic exception scratch
771  * - SPRG2 TLB exception stack
772  * - SPRG3 critical exception scratch and
773  * CPU and NUMA node for VDSO getcpu (user visible)
774  * - SPRG4 unused (user visible)

776  * - SPRG7 critical exception scratch
777  * - SPRG8 machine check exception scratch
778  * - SPRG9 debug exception scratch
779  *
780  * All 32-bit:
781  * - SPRG3 current thread_info pointer
782  * (virtual on BookE, physical on others)
783  *
784  * 32-bit classic:
785  * - SPRG0 scratch for exception vectors
786  * - SPRG1 scratch for exception vectors
787  * - SPRG2 indicator that we are in RTAS
788  * - SPRG4 (603 only) pseudo TLB LRU data

797  * - SPRG7 scratch for exception vectors (not 403)
