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".
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.

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!)

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.
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".
* Turn on DEFAULT_VTABLE_THUNKS. (it is the default anyway, I'm just being
explicit about it, in case it causes us trouble it might be easier for
someone to notice it this way)
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.

For other kinds of binaries, %ebx is still zeroed as before.

with more than one read(). When we detect one, don't
forget to pass it to async_Input() and drop our
terminal back into command mode.
Don't output an extraneous \r if we're passed \r\n
to prompt_vprintf in raw mode.
In particular, replace the unused field pmap::pm_flag by pmap::pm_active,
which is a bit mask representing which processors have the pmap activated.
(Thus, it is a simple Boolean on UPs.)
Also, eliminate an unnecessary memory reference from cpu_switch()
in swtch.s.
