description:
Oops, commit log was missing. It should be:

Revert rev 1.85:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/powerpc/ibm4xx/pmap.c#rev1.85

Not clearly documented in reference manual, but the previous code seems
correct; the operations must be carried out with DMMU disabled. Otherwise,
WIP software single step for userland does not work correctly (stalled
indefinitely at pmap_procwr()).

XXX
pullup to netbsd-9
