mrg 8f7ee94e13 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.

these are the changes to the old Mach VM system to allow both to be
available in the kernel.

thorpej 589a1e440e Clean up and consolidate the old non-contig bootstrap functions, and
rename pmap_steal_memory() to vm_bootstrap_steal_memory().

mrg a20d56e92e add new version of non contiguous memory code, written by chuck cranor,
called "MACHINE_NEW_NONCONGIG".  this is required for UVM, the new VM
system (also written by chuck) that is coming soon.  adds new functions:
	vm_page_physload() -- tell the VM system about an area of memory.
	vm_physseg_find() -- returns index in vm_physmem array that this
		address is in.
and several new versions of old functions/macros defined in vm_page.h.

this is the MI portion.  sparc, and then later i386 portions to come.
all other ports need to change to this ASAP!  (alpha is already being
worked on)
