powerpc/8xx: Fix clearing of bits 20-23 in ITLB miss # # In ITLB miss handled the line supposed to clear bits 20-23 on the L2 # ITLB entry is buggy and does indeed nothing, leading to undefined # value which could allow execution when it shouldn't. # # Properly do the clearing with the relevant instruction. # # Fixes: 74fabcadfd43 ("powerpc/8xx: don't use r12/SPRN_SPRG_SCRATCH2 in TLB Miss handlers") # Cc: stable@vger.kernel.org # v5.0+ # Signed-off-by: Christophe Leroy # Signed-off-by: Michael Ellerman # Link:
