| This bug can cause incorrect code execution under certain |

| every time execution crosses a page boundary), and you may wish |
| to disable it if you have worked around the bug in the compiler |
| (by not placing conditional branches or branches to LR or CTR |
| in the last word of a page, with a target of the last cache |
| line in the next page), or if you have used some other |
| workaround. |
