I'm now porting NetBSD on OpenBlockS (mpc860). But current pmap has
bugs. This is only the reason why I do not import mpc8xx port into
CVS. Since I have to rewrite pmap.c (current implementation is based on
i386 pmap.c). I's a totaly different VM space structure between i386 and
powerpc. Current powerpc implementation has independent kernel VA and user
VA, on the other hands, i386 has same VA space. My idea is, like ibm4xx
ports, add mpc8xx directory into powerpc directoty and share powerpc
specific source code. This means change VM space structure (and pmap.c) to
meet for current powerpc port. Any other good idea ? I welcome any
