116	  This enables a workaround for erratum CPU15 on MPC8xx chips.
117	  This bug can cause incorrect code execution under certain
118	  circumstances.  This workaround adds some overhead (a TLB miss
119	  every time execution crosses a page boundary), and you may wish
120	  to disable it if you have worked around the bug in the compiler
121	  (by not placing conditional branches or branches to LR or CTR
122	  in the last word of a page, with a target of the last cache
123	  line in the next page), or if you have used some other
124	  workaround.
