The commit e0908085fc ("powerpc/8xx: Fix
regression introduced by cache coherency rewrite") is not needed
anymore. The issue was because dcbst wrongly sets the store bit when
causing a DTLB error, but this is now fixed by commit
0a2ab51ffb ("powerpc/8xx: Fixup DAR from
buggy dcbX instructions.") which handles the buggy dcbx instructions on
data page faults on the 8xx.
