47b9dbd431 Two changes to pmap_remove_all: 
1. Switch to pmap_TLB_invalidate from invltlb, eliminating a full TLB
flush where a single-page flush suffices.  (Also, this eliminates some
unnecessary IPIs.)

2. Use "loadandclear" to update the pte, eliminating a race condition
on SMPs.

Change #2 should be committed to -STABLE.

5ef4895832 This is a hack. Cron runs with stdin/out/err pointing to /dev/console, 
which init thoughtfully revoke()'s when starting a getty on ttyv0.  This
Cron's popen() was passing these fd's through to cron children (ie:
sendmail, *not* normal cron jobs).  The side effects were usually
not noticed, but it tripped up postfix which did a sanity check to see
that stdin/out/err were open, and got EBADF even thought the fd's were
in use.  I seem to recall sendmail itself has hacks to work around
this problem, it had a checkfd012() function, possibly for this same
problem.  (Postfix has a workaround too now though..)

This is a hack, not a fix.  It's probably best to check and perhaps
close/reopen() /dev/console if needed each time around the event loop.
It would probably be useful to actually see any error messages from cron.

964462c09d Remove (but leave place markers) P_NOSWAP and P_PHYSIO - they were only 
used for preventing swapouts of the UPAGES and there is another mechanism
for that (PHOLD/PRELE using p->p_lock).

4a40c5e7ee Look at p_lock instead of P_NOSWAP etc as an indicator of unswappability. 
(While here, put a #ifndef pgtok around the macro that gets a redefinition
 warning)

c8da68e917 Don't forcibly kill processes that are locked in-core via PHOLD - it was

51d8a6713f After receiving a connection and doing a reverse 
lookup on the incoming IP, do a forward lookup on
the result and make sure that the IP is in the
resulting list.  If it's not, put the IP number
in utmp/wtmp instead of the rogue name.

5945a079eb When we get an LCP TLU, go into PHASE_AUTHENTICATE 
from any other phase besides PHASE_NETWORK, otherwise
there's a chance that we end up sending auth packets

the dates up with FreeBSD.

fa8e1794b5 There's not much point in the EXPORTMFS #ifdef. I've had this sitting 
in my tree for 12+ months, and I just noticed that NetBSD have (I think,
I've just seen the commit, not the change) just zapped it there.
It wasn't in the options files or LINT either.
