Don't use the nointr pool page allocator for the uao_swhash_elt pool. We
...
need to ensure that these come from a non-pageable kernel map, otherwise
we can run into a deadlock condition (as noticed by Chuck Silvers).

Use the pool allocator w/ the "nointr" pool page allocator for uvm_aobj
...
and uao_swhash_elt structures. Also, fix a bug in uao_set_swlot() where
if setting the swslot to 0 (freeing swap resources), and no swslot was
currently allocated, a new entry would be allocated anyhow (revealed during
pool'ification).

minor consistency nit: the page index into an anon object is always
...
assigned to from integer types, and it is compared to integers. So
let it be an integer instead of vsize_t.

enable hashtables for swapslot storage - deadlock is fixed.

fix initialization of swhash entries.
use malloc(M_NOWAIT) for creating kernel object.
avoid dereferencing a vm_page once the page has been freed.

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. :-)
