the caller assumes this to not happen by means of performing an
indirection without checking the return value. Add KASSERTs to
force a kernel with INVARIANTS to panic. This is a short-term
measure. The pmap code is scheduled to be overhauled.
to deliver a signal and the RSE backing store has been exhausted or
the backing store pointer has been clobbered, we need to make sure
we call userret() and do_ast() when we exit from trap(). Not adjusting
the local variable 'user' in this case will prevent the faulty process
from being terminated and we end up in an infinite fault repetition.

if it was already enabled. We don't want to set it
when it shouldn't be set, we just don't want to
inadvertantly turn it off. This should fix a recent
report of the aic7xxx driver repeatedly complaining of
"unexpected busfree while idle" in one configuration.
successfully mapping our registers. This
avoids the disabling of memory mapped I/O
just because some other driver probe happened
to touch our registers.
This drive delays going async after receiving a WDTR
message. We now send an SDTR message after a WDTR even
if our goal is to go async. This should work even for
confused devices.
If we get an unexpected busfree when attempting a WDTR
or SDTR, only set the goal negotiation parameters we were
trying to negotiate to off. This means that should a WDTR
message fail, we will still try an SDTR if our goal is
non-async.
Fix a few more places where we were looking at goal.period
instead of goal.offset for determining if we should be
negotiating sync. This should not have any impact on
our behavior, but the offset is more definitive and should
be used.

Switch ah?_reset() to take an additional "reinit" argument.
Use this instead of init_level to determin if the chip
should be fully reinitialized after a chip reset. This
is required so that ah?_shutdown() can reset the chip
without side-effects.

Implement ahd_suspend() and ahd_resume().
aic7xxx.c:
Change ahc_loadseq() to *not* restart the sequencer.
This brings the loadseq behavior in line with that
of the 7902 driver and also simplifies the init routine.
Correct the resume routine to enable interrupts and
restart the sequencer.
always kernel space. It should be treated as user space when run with
user privileges (which is the case for the signal trampolines). This
fixes its only use in a KASSERT in subr_trap.c.

* No need to report that it is on a sleep queue if it is actually sleeping
* "Normal" state is almost ubiquitous.. only report abnormal states.
* increment the #lines count for each separate thread shown in threaded

makes it less likely that a threaded program will make all the data

while after the legacy device was added since this driver hangs from
legacy and not nexus.
- Make several methods non-static so they can be reused in a mptable
host -> pci bridge driver that will be added at a later date.
- Let legacy_pcib() use pcibios_pcib_route_interrupt() directly instead of
wrapping it in a private function. Originally, I thought I was going to
have the nexus_pcib() driver make a runtime APIC vs. 8259A check and call
the appropriate routing method (MPTable vs. PIR) that way, but it ended
up being cleaner to make nexus_pcib() just work with PIR and have a
separate host -> pci bridge driver for the mptable/apic case.
bridge lives on (i.e., the parent bus) when probing the PIR table for a
bus. This could cause the PCIBIOS PCI-PCI bridge driver to bogusly attach
to bridges that weren't in the PIR but whose parent bus was in the PIR.
- Initialize "rval", which would be used uninitialized
if al or pl options were set.
- Don't pass an empty string to login(1) as a user name
(this could be triggered by entering a name and then killing it
with backspace or ^U.)
- Don't loop endlessly if the al option specifies a bogus (i.e.,
not alphanumeric) auto-login name.
- Don't pass a bogus user name to login(1) if a good name were
entered and then killed with ^U.
- Exit with status 0, not 1, on receiving an EOF character,
since it's not a error condition.
