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.

avoids the disabling of memory mapped I/O

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.
aic79xx.c:
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.

fit on one line. Account for threads better.
* 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
programs.
makes it less likely that a threaded program will make all the data
on a screen overflow off the top of the screen.

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.

attribute name of "" from ffs_getextattr(). Invoking VOP_GETETATTR()
with an empty name is now no longer supported; user application
compatibility is provided by a system call level compatibility
wrapper. We make sure to explicitly reject attempts to set an EA

we were passing in a void* representing the PCB of the parent thread.
Now we pass a pointer to the parent thread itself.
The prime reason for this change is to allow cpu_set_upcall() to copy
(parts of) the trapframe instead of having it done in MI code in each
caller of cpu_set_upcall(). Copying the trapframe cannot always be
done with a simply bcopy() or may not always be optimal that way. On
ia64 specifically the trapframe contains information that is specific
to an entry into the kernel and can only be used by the corresponding
exit from the kernel. A trapframe copied verbatim from another frame
is in most cases useless without some additional normalization.
Note that this change removes the assignment to td->td_frame in some
implementations of cpu_set_upcall(). The assignment is redundant.
A previous call to cpu_thread_setup() already did the exact same
assignment. An added benefit of removing the redundant assignment is
that we can now change td_pcb without nasty side-effects.
This change officially marks the ability on ia64 for 1:1 threading.

got fixed two weeks after the ia64 version was copied from the alpha
version (see rev 1.32 of sys/alpha/alpha/mem.c). As such, we were
missing the same continue as on alpha.
While here, add a default case for the device minor switch and do
some general style(9) cleanups.
WARNING: this file still has bugs. When reading from region 6 or
region 7, we don't validate the physical address. One can trivially
cause a machine check by trying to read from address 0xFFFFFFFFFFFFFFF0
or something that uses the unimplemented physical address bits.

this for i386 anyways once SMP support is done. Having this enabled fixes

Create a GEOM provider instead of using disk_create()
Use the GEOM OAM api for configuration.
