Hi folks...

For those of you running -current who would like to try out the new
virtual memory system, I have implemented the necessary changes and
committed them to the source tree.  Your SUP tomorrow should pick them

PLEASE NOTE!  You'll need some changes to sys/uvm which are not in the
tree just yet.  I have informed Chuck Cranor (the UVM author) that the
changes in question do work, and he should be committing those shortly
(he wanted to tidy them up a bit first).

To use it, you need to:

	(a) Add "options UVM" to you kernel config file, rerun config,
	    make clean, make depend, and make.  Then boot the resulting

	(b) Put "UVM=yes" in your /etc/mk.conf file, and then do a
	    "make build" in /usr/src to build a userland compatible
	    with UVM.  This affects kmem-using programs.

If you have any problems, please send a bug report with send-pr(1) and
I'll look at it as quickly as possible.
