mrg 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.

thorpej b861180119 * Rename uvm_fault_unwire() to uvm_fault_unwire_locked(), and require that
the map be at least read-locked to call this function.  This requirement
  will be taken advantage of in a future commit.
* Write a uvm_fault_unwire() wrapper which read-locks the map and calls
  uvm_fault_unwire_locked().
* Update the comments describing the locking contraints of uvm_fault_wire()
  and uvm_fault_unwire().

thorpej 2c3dc83a64 Keep interrupt-safe maps on an additional queue. In uvm_fault(), if we're
looking up a kernel address, check to see if the address is on this
"interrupt-safe" list.  If so, return failure immediately.  This prevents
a locking screw if a page fault is taken on an interrupt-safe map in or
out of interrupt context.

thorpej 8d8badbd8f Make uvm_fault_unwire() take a vm_map_t, rather than a pmap_t, for
consistency.  Use this opportunity for checking for intrsafe map use
in this routine (which is illegal).

thorpej 195c1a2741 Pass an access_type to uvm_fault_wire(), which it forwards on to
uvm_fault().

chuck 1b59a238c4 remove unused share map code from UVM:
- simplify uvm_faultinfo in uvm_fault.h (parent map tracking no longer needed)
 - adjust locking and lookup functions in uvm_fault_i.h to reflect the above
 - replace ufi.rvaddr with ufi.orig_rvaddr in uvm_fault.c since rvaddr is
	no longer needed.
 - no need to worry about share map translations in uvm_fault().  simplify.

mrg 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.  :-)
