Move the PG_BUSY in vm_fault to the correct place.
Remove redundant/unnecessary code in pmap.c.
Properly block on rundown of page table pages, if they are busy.
I think that the VM system is in pretty good shape now, and the following
individuals (among others, in no particular order) have helped with this
recent bunch of bugs, thanks! If I left anyone out, I apologize!

name (ie; strip off the domain). Given a hostname 'fooey.bar.com', the
previous code returned a system name of 'fooey.ba', instead of the more
correct 'fooey'. SCO uses 'uname' for many things, including some of
it's socket code so this patch is necessary for running certain legacy
SCO apps. :)
A variant of this code has been running on my box for 2 months now.
some problems with the page-table page management code, since it can't
deal with the notion of page-table pages being paged out or in transit.
Also, clean up some stylistic issues per some suggestions from

circumstances, caused perfectly good connections to be dropped. This
happened for connections over a LAN, where the retransmit timer
calculation TCP_REXMTVAL(tp) returned 0. If sending was blocked by flow
control for long enough, the old code dropped the connection, even
though timely replies were being received for all window probes.

swap space. If there is a hold_count flaw for page-table
pages, clear the page before freeing it to lessen the chance of a system
crash -- this is a robustness thing only, NOT a fix.
operations don't work with FICTITIOUS pages.) Also, close a window
between PG_MANAGED and pmap_enter that can mess up the accounting of
the managed flag. This problem could likely cause a hold_count error
for page table pages.
close some windows that are opened up by page table allocations. The
prefaulting code no longer uses hold counts, but now uses the busy
flag for synchronization.

this outb got lost.
Turn ATN on ourselves as appropriate during a parity error instead of relying
on ENAUTOATNP.
Don't use a loop in RESTART_SEQUENCER. Its not necessary.

The nesting rules of macros are different, which required some changes.
Use __CONCAT(x,y) instead of /**/.
Redo some comments to use /* */ rather than "# comment" because the ansi
cpp cares about those, and also cares about quote matching.
cc -c -x assembler-with-cpp -o file.o file.s.
This means that any cpp fatal errors will now be detected, as well as
running *.s files through an ansi cpp instead of a traditional cpp.
(fixes to allow *.s to compile under both ansi and traditional to follow)
