| Hi Christos,
|      Just a quick one...
|      The patches I submitted in the pr are in a terrible format. I will
| repost them as a diff -ruN from inside sys/, to the pr tonight.
|      Please note I have still not quite got my head all around the amd64
| pmap so I am not sure if this change is even worthwhile.... However,
| i've been running these patches on my development/main pc at home and
| I haven't noticed any problems. Also, the patches only do the pool
| thing. I have not ported any of openbsd's other pmap changes.
|     On another note, I am in the process of rewriting the page table code
| on amd64 to make use of the long mode 2M page size feature and the
| change to the page table structure for this page size. (I have
| rewritten pte.h but the changes emmanate through other code as well,
| eg. pmap.{h,c} & locore.S) Are you someone I can ask a question of
| here and there with respect to the amd64 implementation? PS: This is
| only a hobby for me so don't hold your breath :-) I'm also thinking of
| going through locore.S as well...
| Take care,

Ok, sounds good. I will not touch it until you tell me.
