Subject: [PATCH] powerpc 8xx: Reverting commit 

e0908085fc2391c85b85fb814ae1df377c8e0dcb which has become useless

The commit e0908085fc2391c85b85fb814ae1df377c8e0dcb 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 

0a2ab51ffb8dfdf51402dcfb446629648c96bc78

which handles the buggy dcbx instructions on data page faults on the 

8xx.
