# When we have VMAP stack, exception prolog 1 sets r1, not r11. # # When it is not an RTAS machine check, don't trash r1 because it is # needed by prolog 1. # # Fixes: da7bb43ab9da ("powerpc/32: Fix vmap stack - Properly set r1 before activating MMU") # Fixes: d2e006036082 ("powerpc/32: Use SPRN_SPRG_SCRATCH2 in exception prologs") # Cc: stable@vger.kernel.org # v5.10+ # Signed-off-by: Christophe Leroy # [mpe: Squash in fixup for RTAS machine check from Christophe] #
