2f159a1bac remove/move more mach vm header files: 
<vm/pglist.h> -> <uvm/uvm_pglist.h>
	<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
	<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

6e5b64c8a0 Merge parts of chs-ubc2 into the trunk: 
Add a new type voff_t (defined as a synonym for off_t) to describe offsets
into uvm objects, and update the appropriate interfaces to use it, the
most visible effect being the ability to mmap() file offsets beyond
the range of a vaddr_t.

Originally by Chuck Silvers; blame me for problems caused by merging this
into non-UBC.

16f0ca3612 add support for ``swapctl -d'' (removing swap space).

f3a668ed84 eliminate the PMAP_NEW option by making it required for all ports. 
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.

23e83a7ac7 When handling the MADV_FREE case, if the amap or aobj has more than 
one reference, go through the deactivate path; the page may actually
be in use by another process.

Fixes kern/8239.

3f176180d5 Garbage collect thread_sleep()/thread_wakeup() left over from the old 
Mach VM code.  Also nuke iprintf(), which was no longer used anywhere.

Add proclist locking where appropriate.

f455dd6596 add a `flags' argument to uvm_pagealloc_strat(). 
define a flag UVM_PGA_USERESERVE to allow non-kernel object
allocations to use pages from the reserve.

5dd4b45577 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).

5a4981d9b8 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).

9b25897ec0 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.

f2caacc717 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.  :-)
