Change the format strings in many of the assertions that were recently

since the link takes a bit to negotiate, the information is pretty
much never available during the probe. As such, the boot output
pretty much always prints N/A for speed and duplex. Since we print
out the output of ifconfig during the user space boot, this early
boot information is also generally redundant, and added to the noise.

before dereferencing it. Certain corrupt kernel modules might not have
a valid hash table, and would cause a kernel panic when they were loaded.
Instead of panic'ing, the kernel now prints out a warning that it is
missing the symbol hash table.

PCI-ISA bridge. Thus, when viapm0 or viapropm0 attaches, isab0 dosen't
attach so there is no isa0 bus hung off of that bridge. In the non-ACPI
case, legacy0 will add an isa0 anyway as a fail-safe, but ACPI assumes that
any ISA bus will be enumerated via a bridge. To fix this, call
isab_attach() to attach an isa0 ISA child bus device if the pm or propm
device we are probing is a PCI-ISA bridge. Both drivers now have to
implement the bus_if interface via the generic methods for resource
allocation, etc. to work. Also, we now add 2 new ISA bus drivers that
attach to viapm and viapropm devices.

- Prefer '_' to ' ', as it results in more easily parsed results in
memory monitoring tools such as vmstat.
- Remove punctuation that is incompatible with using memory type names
as file names, such as '/' characters.
- Disambiguate some collisions by adding subsystem prefixes to some
memory types.
- Generally prefer lower case to upper case.
- If the same type is defined in multiple architecture directories,
attempt to use the same name in additional cases.
Not all instances were caught in this change, so more work is required to

a seek just back from the end of the 'disk', which resulted in a > 4G
seek, causing gdb psim to exit since it only supports 32-bit seeks.
The size of the disk should really be specified in the psim device tree,
but for now do the minimal amount of work to get psim to run again.

OpenFirmware. FreeBSD/ppc uses SPRG0 as the per-cpu data area pointer,
and SPRG1-3 as temporary registers during exception handling. There
have been a few instances where OpenFirmware does require these to
be part of it's context, such as cd-booting an eMac.

following the protocol pru_listen() call to solisten_proto(), so
that it occurs under the socket lock acquisition that also sets
SO_ACCEPTCONN. This requires passing the new backlog parameter
to the protocol, which also allows the protocol to be aware of
changes in queue limit should it wish to do something about the
new queue limit. This continues a move towards the socket layer
acting as a library for the protocol.

interface. This change has been tested with IPv4 and UNIX domain
sockets, but not other protocols.

issuing an AIOSFMT ioctl with an all-zeroes snd_chan_param would

trying to access user-space stack addresses when a user fault
is encountered, as occurs when GEOM KTR code is handling a page fault

It may be possible to walk beyond the trap-frame if it is a kernel fault,
as db_backtrace() does, but I don't think that complexity is needed in

convert to or from timeval frequently.
Introduce function itimer_accept() to ack a timer signal in signal
acceptance code, this allows us to return more fresh overrun counter
than at signal generating time. while POSIX says:
"the value returned by timer_getoverrun() shall apply to the most
recent expiration signal delivery or acceptance for the timer,.."
I prefer returning it at acceptance time.
Introduce SIGEV_THREAD_ID notification mode, it is used by thread
libary to request kernel to deliver signal to a specified thread,
and in turn, the thread library may use the mechanism to implement
SIGEV_THREAD which is required by POSIX.
Timer signal is managed by timer code, so it can not fail even if
signal queue is full filled by sigqueue syscall.
actual resource values we received from the system rather than the range
we requested. Since we request a range starting at 0, we would record
that number. Later, since this == 0, we'd allocate again. However,
we wouldn't write the new resource into the BAR. This resulted in
a resource leak as well as a BAR that couldn't access the resource at
all since rman_get_start, et al, were wrong.

the ifp, so you can't call it before doing if_alloc(). Also, there's
really no need to call it here anyway: the code I originally ported from
OpenBSD incorrectly set the station address only once at device attach
time, instead of setting in txp_init(). This meant you couldn't change
the address with ifconfig txp0 ether xx:xx:xx:xx:xx:xx. I added the
call to txp_set_filter() in txp_init() to correct this, but forgot to
remove the call from txp_attach(). Until now, it never mattered.
With this fix, the txp driver tests good:
txp0: <3Com 3cR990-TX-97 Etherlink with 3XP Processor> port 0xb800-0xb87f mem 0xe6800000-0xe683ffff irq 12 at device 10.0 on pci0
