#     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")
