1. Don't bother checking object->ref_count == 1 in order to set
OBJ_ONEMAPPING. It's a waste of time. If object->ref_count == 1,
vm_map_entry_delete will "run-down" the object and its pages.
2. If object->ref_count == 1, ignore OBJ_ONEMAPPING. Wait for
vm_map_entry_delete to "run-down" the object and its pages.
Otherwise, we're calling two different procedures to delete
the object's pages.
Note: "vmstat -s" will once again show a non-zero value
for "pages freed by exiting processes".

If somebody does an execv("foo", NULL) (which theoretically is an error),
avoid crashing inside rtld (since it's easy) since everything else handles
it. Of course, if the target program checks argv[], it'll fall over.

Add an 'al' (autologin username) capability to getty/gettytab. This is a
damn useful thing for using with serial consoles in clusters etc or secure
console locations. Using a custom gettytab entry for console with
an entry like 'al=root' means that there is *always* a root login ready on
the console. This should replace hacks like those which go with conserver
etc. (This is a loaded gun, watch out for those feet!)
Make firmware revision a triple. Clean up some FC init stuff for
board versions with no BIOS. Separate mailbox interrupts from
IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not
after you clear it (potential race condition). Clear out older broken
BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup
if already in LVD mode. Note usage of presumptive 1040C revision. For
all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state
as unknown as well as marking the need to do a getpdb on targets- after
a LIP for certain the f/w has to do PRLI/PLOGI for all targets again
and marking f/w state as unknown gives us a fighting chance to (start
to) hold up for that to complete.
Remove incorrect BIG_ENDIAN defines and substitute in the SBus only macros
that will SBusify an isp header or the lun/target portions of a request IOCB-
and have these only valid iff __sparc__ (no non-sparc SBus machine that *I*
know about).
Arguments with whitespaces are easy to fix, but in combination with
shell metachars that should not be evaluated it is very hard, probably
impossible to fix without going to a line-oriented solution.
Next time I will believe Henry Spencer when he says "this looks easy
to fix but isn't".
* Protect ourselves from any previously defined options.
* Turn on DEFAULT_VTABLE_THUNKS. (it is the default anyway, I'm just being

Commit msg for rev 1.20 should probably have added that gnu/lib/libregex was
the only lib that was using the SHLIB_* values from gnu/lib/Makefile.inc.
Thus I simply added the to the Makefile here.
Makefile.inc was politing all subdir's with SHLIB_{MAJOR,MINOR} definitions.
Since we aren't keeping all the GNU libs at the same versions, this is
useless and causes us to build a shared libgcc, which we don't want to do.
1) Fix the case where a shellscript using getopt is called with a
parameter that has space in it, both in getopt.c and in the manpage
example.
2) Fix the example in the manpage. The set(1) command is required to
return 0 (POSIX 1003.2, section 3.14.11), so you can't test for
getopt's exit status like the example did:
#! /bin/sh
set -- `getopt abo: $*`
if test $? != 0 # wrong, tests for set's exit status, which is
# always zero, no for getopt(1)'s.
Fixes PR bin/5845, which thought it was getopt's fault, but in fact
the manpage was wrong.
I also updated the example to be more useful and updated the BUGS
section.
Restore support for executing BSD/OS binaries on the i386 by passing

On FreeBSD/alpha, ps(1) does not correctly report process start times
and CPU runtime because it can't access the user area via /proc/<pid>/mem.
This is because the uarea is not mapped into the process address space
at USRSTACK on the alpha like it is on the x86.
Since I'm haven't been able to wrap my brain around the VM system enough
to be able to figure out how to achieve this mapping, and since it's
questionable that such an architectural change is correct, I implemented
a workaround to allow ps(1) to read the uarea from /dev/kmem using
kvm_read() instead of from the process address space via kvm_uread().
The kludge is hidden inside #ifdef __alpha__/#endif so as not to impact
the x86. (Note that top(1) probably uses this same gimmick since it works
on FreeBSD/alpha.)
Use new -T switch to turn on immediate interruptibilty in shell

The immediate execution of traps I introduced in September 1998 (to
make /etc/rc interruptible in cases when programs hang with blocked
signals) isn't standard enough.
It is now switched off by default and a new switch -T enables it.
You should update /etc/rc to the version I'm about to commit in a few
minutes to keep it interruptible.

* Deal with libgcc's move from gnu/usr.bin/cc to gnu/lib.
Move was necessary as libgcc should be built with the freshly built
compiler and thus we must wait until the freshly built bits have been
installed somewhere so we can use them. libgcc presence in gnu/usr.bin/cc/
gets in the way of building the new compiler. We could have either
cd'ed to specific directories w/in gnu/usr.bin/cc/ and built and installed
individual bits, or move libgcc out of the way and let our normal subdir
building process work.
* Don't build libgcc in "bootstrap-libraries:" target it should not be
assumed the currently installed compiler can correctly build libgcc.
