file is processed by passing its name in argv[1]:
return(mod_loadobj(typestr, argv[1]));
however, it is not tested to see if argv[1] actually is defined.
At best, mod_loadobj() near line 244 returns an error like
"can't find 'garbage'" but if the "filename" entered is sufficiently
long, some buffer gets overrun. Of course, "load -t filename" is
actually a typo because we meant to type "load -t mfs_root filename";
nevertheless, a hung machine seems like too harsh a punishment for
such a small typo...

breakage:
- call PCIB_ROUTE_INTERRUPT() regardless of how valid the intline looks.
Some alphas leave garbage in the intline and leave the intr mapping
to OS platform support routines that map slots/buses to intlines
- Down in the alpha pci code, first try platform.pci_intr_route() and
if it doesn't exist or returns garbage, just read the intline out of
config space.
tested on AS500 (garbage in intline) and UP1000 (PC-like, intline is valid)
Note that a nice little hack like the APIC_IO section of pci_cfgregread()
is not workable. This is because the calling interface for
alpha_pci_route_interrupt() requires us to figure out the bus/slot/etc
from a device_t. At pci_read_device() time, we don't have a device_t
for the bus/slot/func in question.
Noteworthy changes include:
* Use getopt(3).
* Fix overflows in -b and -w options.
* Use strlcpy(3) and snprintf(3) in favor of strcpy(3) and
sprintf(3), respectively. Also check return values of the former
two.
* Fix lots of other gratuitous differences with OpenBSD.

Also take a stab at cleaning up BDECFLAGS and convert all uses of
NOSTR, NIL, NONE, NOVAR, NOGRP, NOGE to NULL. Also kill 'register' to
get diffs somewhat closer to OpenBSD/NetBSD.
There are no functional changes however.

instead of using two malloced arrays for storing channel lists, use an
slist. convert the sndstat device to use sbufs and optionally provide more
detail about channel state.
vchans are software mixed playback channels. they are not enabled by this
commit. they use the feeder infrastructure to emulate normal playback
channels in a manner transparent to applications, whilst providing as many
channels are desired, especially suitable for devices with only one hardware
playback channel. in the future they will provide additional features.
those wishing to test this functionality will need to add vchan.c to
sys/conf/files and use 'sysctl -w hw.snd.pcm0.vchans' to enable it.

the only time CONS_CLRHIST wouldn't be defined is when kbdcontrol is
being built in bootstrap-tools, and -c isn't needed then.

SC_DEV isn't NULL; if it is, evaluate to NULL and don't dereference
NULL. Callers of VIRTUAL_TTY must already check for the result being
NULL since si_tty can be NULL, so this should be safe.
This fixes a panic when trying to switch to a different vty in an
environment such as userconfig (-c option to the kernel).

were incorrect in the case where the credential was updated, skipping
the setting of the saved uid and gid when new credentials were generated.
This change corrects that problem by handling the newcred!=NULL case
correctly.

This problem only exists in -CURRENT. Most often it is reproduced when
compiling some perl extension manually. Make test uses PERL_DL_NONLAZY,
and if a tested module uses POSIX, boom!
Luckily, we don't see it very often, mostly because the vast majority of
p5 ports do not perform the `make test' step.

The patch I used isn't quite the one Lars suggested, but the size
of the largest datagram you can recv isn't #defined anywhere, and
probably isn't even bounded for some protocols.
