Add a couple of comments about how the pool page allocator functions
...
can be called with a map that doens't require spl protection.

We need to be able to specify a uvm_object to the pool page allocator, too.

only pages explicitly wired by a user process should be counted.

initial import of the new virtual memory system, UVM, into -current.
...
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the UVM kernel code portion.
this will be KNF'd shortly. :-)
