and the reference to db_regs is *extern* from alpha/include/db_machdep.h
(put it in alpha/alpha/machdep.c)- this avoids the problems we've had
about different 'common' sizes prohibiting the kernel from linking.
intermodule communication is done via kobj calls. If anything
currently depends on them, let it break so that we can fix it. Maybe
we'll need to export some of the card_if.c or power_if.c symbols, but
I think those should be in the base kernel (since all *_if.c should be
in the base kernel for just these reasons).

KMODDEPS seems to be a no-op in HEAD, but is required in RELENG_4,
where MODULE_DEPEND seems to be a no-op.
Therefore, this change is harmless in -CURRENT, but will fix the
dependencies when merged to RELENG_4, where they are currently not
registered!

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
an exploitable race in AIO.
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.
Alpha can verify that it compiles fine there, too, this should be moved
to the MI section (or that problem fixed); I've only had x86 hardware to
est with.

but time and other interests is making it hard. Open the door for
new blood and fresh tactics now that the Linuxulator has had its
facelift.
Thanks to all who contributed during my tour of duty!
src/sys/dev/an/if_an_pccard.c rev 1.10 change requires to include
"card_if.h" but Makefile doesn't know about this file. Without this,
kernel build will fail at this driver.
- Add S4BIOS sleep implementation. This will works well if MIB
hw.acpi.s4bios is set (and of course BIOS supports it and hibernation
is enabled correctly).
- Add DSDT overriding support which is submitted by takawata originally.
If loader tunable acpi_dsdt_load="YES" and DSDT file is set to
acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml),
ACPI CA core loads DSDT from given file rather than BIOS memory block.
DSDT file can be generated by iasl in ports/devel/acpicatools/.
- Add new files so that we can add our proposed additional code to Intel
ACPI CA into these files temporary. They will be removed when
similar code is added into ACPI CA officially.

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
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)

ethernet controllers. This adds support for the 3Com 3c996-T, the
SysKonnect SK-9D21 and SK-9D41, and the built-in gigE NICs on
Dell PowerEdge 2550 servers. The latter configuration hauls ass:
preliminary measurements show TCP speeds of over 900Mbps using
only normal size frames.
TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.
Still need to fix autonegotiation support for 1000baseSX NICs, but
beyond that, driver is pretty solid.
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

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.
o Fix or improve numerous syscalls and prototypes.
o Reduce style(9) violations while I'm here. Especially indentation
inconsistencies within the same file are addressed. Re-indenting
did not obfuscate actual changes to the extend that it could not
be combined.
NOTE: I spend some time testing these changes and found that if there
were regressions, they were not caused by these changes AFAICT.
It was observed that installing a RH 7.1 runtime environment
did make matters worse. Hangs and/or reboots have been observed
with and without these changes, so when it failed to make life
better in cases it doesn't look like it made it worse.
