#     powerpc/32s: Fix RTAS machine check with VMAP stack
#     
#     When we have VMAP stack, exception prolog 1 sets r1, not r11.
#     
#     Fixes: da7bb43ab9da ("powerpc/32: Fix vmap stack - Properly set r1 before activating MMU")
#     Fixes: d2e006036082 ("powerpc/32: Use SPRN_SPRG_SCRATCH2 in exception prologs")
