Remove the explicit call to aio_proc_rundown() from exit1(), instead AIO
will use at_exit(9).
Add functions at_exec(9), rm_at_exec(9) which function nearly the
same as at_exec(9) and rm_at_exec(9), these functions are called
on behalf of modules at the time of execve(2) after the image
activator has run.
Use a modified version of tegge's suggestion via at_exec(9) to close

Fix SYSCALL_MODULE_HELPER such that it's archetecuterally neutral,
the problem was that one had to pass it a paramater indicating the
number of arguments which were actually the number of "int". Fix
it by using an inline version of the AS macro against the syscall
arguments. (AS should be available globally but we'll get to that
later.)
Add a primative system for dynamically adding kqueue ops, it's really
not as sophisticated as it should be, but I'll discuss with jlemon when
he's around.
- Temporary fix a bug of Intel ACPI CA core code.
- Add OS layer ACPI mutex support. This can be disabled by
specifying option ACPI_NO_SEMAPHORES.
- Add ACPI threading support. Now that we have a dedicate taskqueue for
ACPI tasks and more ACPI task threads can be created by specifying option
ACPI_MAX_THREADS.
- Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
caller's buffer unless AE_BUFFER_OVERFLOW occurs. Also CM battery's
evaluations were changed to use acpi_EvaluateIntoBuffer().
- Add new utility function acpi_ConvertBufferToInteger().
- Add simple locking for CM battery and temperature updating.
- Fix a minor problem on EC locking.
- Make the thermal zone polling rate to be changeable.
- Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
entering Debugger is easier to investigate the problem rather than panic.

This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications. The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
- APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
- APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
- APMIO_GETINFO and APMIO_GETINFO_OLD
- APMIO_GETPWSTATUS
With above, many APM applications which get batteries, ac-line

wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)

o Introduce private types for use in linux syscalls for two reasons:
1. establish type independence for ease in porting and,
2. provide a visual queue as to which syscalls have proper
prototypes to further cleanup the i386/alpha split.
Linuxulator types are prefixed by 'l_'. void and char have not
been "virtualized".
o Provide dummy functions for all syscalls and remove dummy functions
or implementations of truely obsolete syscalls.
o Sanitize the shm*, sem* and msg* syscalls.
o Make a first attempt to implement the linux_sysctl syscall. At this
time it only returns one MIB (KERN_VERSION), but most importantly,
it tells us when we need to add additional sysctls :-)
o Bump the kenel version up to 2.4.2 (this is not the same as the
KERN_VERSION MIB, BTW).
o Implement new syscalls, of which most are specific to i386. Our
syscall table is now up to date with Linux 2.4.2. Some highlights:
- Implement the 32-bit uid_t and gid_t bases syscalls.
- Implement a couple of 64-bit file size/offset bases syscalls.

- Kill the ready queue, and handle a busy response to mly_start in callers

- Don't advertise physical channels as SCSI busses by default.
- use the SIM queue freeze capability rather than queueing CDBs internally.
- force bus reprobe at module load time.
- Clean up more resources in mly_free.
- Tidy up debugging levels.
- Tidy up handling of events (mostly just code cleanliness).
- Use explanatory macros for operations on bus/target/channel numbers.
- Move the lance_probe function to if_lnc.c.

pccardd(8) could load and unload drivers dynamically...). Mainly, it
tries to find fdc0 on the PCI bus for whatever obscure reasons, but i

already better than before, and i'm tired of maintaining too many private

could only get a chance of testing it under 4.3, but together with the
if_oltr.c fixes at least it seems to work now. If someone has the chance
to test this under -current, please do.
Unfortunaltey, the TR code itself (if_iso88025subr.c) is not written
in a way that would allow to make a seaparate KLD out of it. By now,
just link it directly into the oltr KLD since it's probably the POLA
to be able to load the TR code together with the only TR hardware
driver we've got by now.
I've got one single unexplained panic (in doreti_switch or somewhere
there, calling a 0xc1XXXXXX address that did no longer belong to the

This driver supports PCI Xr-based and ISA Xem Digiboard cards.
dgm will go away soon if there are no problems reported. For now,

donations welcome).
The digi_* pseudo-drivers are not drivers themselves but contain
the BIOS and FEP/OS binaries for various digiboard cards and are
auto-loaded and auto-unloaded by the digi driver at initialisation
time. They *may* be configured into the kernel, but waste a lot
of space if they are. They're intended to be left as modules.
The digictl program is (mainly) used to re-initialise cards that
