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.

c0ac678704 I should have made uvm_page_physload() take paddr_t's instead of vaddr_t's. 
Also, add uvm_coredump32().

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.

d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

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.

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)
