Nix mark 4

Besides the new mount table... 16k user pages, 4k kernel pages (support for 2M/1G), and no BSS segment. The cache relies on segments, the kernel malloc asks for pages like everybody else, and there is a reworked memory subsystem. Will post a link to a new TR soon.

9pix for plan 9

There is a copy of the stock 9 kernel modified to include the changes described in previous entries of this blog at sources.lsub.org/9n. See 9n.README.
The mark II nix will be made public later this year at the same place.
