1a8c7604f4 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 rest of the MI portion changes.

this will be KNF'd shortly.  :-)

2b65c6c346 Delay turning off P_TRACED until the process is actually waited on. It can't 
have any signals delivered while exiting, so this should be okay.  Change the
test for a traced process in wait4() to exclude a process that was started by
the debugger; in this case, only one SIGCHLD should be delivered.

701f15db33 Reinstate P_FSTRACE, with different semantics: 
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
  was attached.

for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy

32c2dba8da Mike Karels' solution to Andrew Herbert <andrew@werple.apana.org.au>'s 
kern_exit race condition problem.  this is a hack:
	don't vrele() or vgoneall() if we don't have the vnode
	any more.  no vgoneall() is necessary, because if the refcnt
	is zero, there's nobody to take it away from!
a possible "real" long term solution would be to change the extra ref
into a bit in the vnode's flags, and DTRT in the places where the last
ref is killed.  That has some problems, too.

de69711383 These changes are due to a mismatch with user functions prototyped as 
func(short) and the fact the the kernel uses full ints.  This caused
problems on the pc532 port.  These fixes take the good 16 bits passed
by the user program and converts them into the correct form for the
kernel.
