6a8954b084 Fix StallOp implementaion. I've noticed that StallOp corresponds to
OsdSleepUsec(), SleepOp corresponds to OsdSleep() by reading ACPICA
source code.
 - Add OsdSleepUsec() which uses DELAY() simply.
 - Change unit of acpi_sleep() argument; microseconds to milliseconds.

2da5dbec3e Put on my nuclear-grade asbestos suit and cvs rm the old, broken, sound
drivers (again).  These drivers have not compiled for 5-6 months.
Now that the new sound code supports MIDI, the major reason we had for
reviving it is gone.  It is a far better investment polishing the new
midi code than trying to keep this on life support.  Come 5.0-REL, if
there are major shortcomings in the pcm sound driver then maybe we can
rethink this, but until then we should focus on pcm.

Remember, these have not been compilable since ~April-May this year.

2cf3496166 Fix the no-pci case of attaching isa, eisa and mca devices.
device_add_child() is meant to be called by the bus add_child method, not
to replace the bus add_child method.  We could have called nexus_add_device
directly too, that would have also worked.

 - Move event handling into acpi_event.c

 - Move find-RSDT and find-ACPI-owned-memory into acpi_machdep

 - Removed unnecessary includes
 - Minor style and commenting fixes

7d03271452 Big mbuf subsystem diff #1: incorporate mutexes and fix things up somewhat
to accomodate the changes.

 Here's a list of things that have changed (I may have left out a few); for a
 relatively complete list, see http://people.freebsd.org/~bmilekic/mtx_journal

   * Remove old (once useful) mcluster code for MCLBYTES > PAGE_SIZE which
     nobody uses anymore. It was great while it lasted, but now we're moving
     onto bigger and better things (Approved by: wollman).

   * Practically re-wrote the allocation macros in sys/sys/mbuf.h to accomodate
     new allocations which grab the necessary lock.

   * Make sure that necessary mbstat variables are manipulated with
     corresponding atomic() routines.

   * Changed the "wait" routines, cleaned it up, made one routine that does
     the job.

   * Generalized MWAKEUP() macro. Got rid of m_retry and m_retryhdr, as they
     are now included in the generalized "wait" routines.

   * Sleep routines now use msleep().

   * Free lists have locks.

   * etc... probably other stuff I'm missing...

  Things to look out for and work on later:

   * find a better way to (dynamically) adjust EXT_COUNTERS

   * move necessity to recurse on a lock from drain routines by providing
     lock-free lower-level version of MFREE() (and possibly m_free()?).

   * checkout include of mutex.h in sys/sys/mbuf.h - probably violating
     general philosophy here.

   The code has been reviewed quite a bit, but problems may arise... please,
   don't panic! Send me Emails: bmilekic@freebsd.org

b6c8407840 Get out the roto-rooter and clean up the abuse of nexus ivars by the
i386/isa/pcibus.c.  This gets -current running again on multiple host->pci
machines after the most recent nexus commits.  I had discussed this with
Mike Smith, but ended up doing it slightly differently to what we
discussed as it turned out cleaner this way.  Mike was suggesting creating
a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(),
but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform
property, not a quirk of a given implementation.  This does use the ivar
methods but does so properly.  It also now prints the physical pci bus that
a host->pci bridge (pcib) corresponds to.

73334a4329 Add a new driver for the AMD PCnet/FAST, FAST+ and Home PCI adapters.
Previously, these cards were supported by the lnc driver (and they
still are, but the pcn driver will claim them first), which is fine
except the lnc driver runs them in 16-bit LANCE compatibility mode.
The pcn driver runs these chips in 32-bit mode and uses the RX alignment
feature to achieve zero-copy receive. (Which puts it in the same
class as the xl, fxp and tl chipsets.) This driver is also MI, so it
will work on the x86 and alpha platforms. (The lnc driver is still
needed to support non-PCI cards. At some point, I'll need to newbusify
it so that it too will me MI.)

The Am79c978 HomePNA adapter is also supported.

21144e2fde Brought back schedsofttty() (SMPng casualty). Didn't bring back the
other schedsoft*() functions since they have never been used.

Removed confused comment about not needing these functions.  The
functions delay scheduling of SWIs until the next hardclock tick.
For devices that only deliver a few characters per interrupt, this
reduces the number of calls to the scheduler by a large factor (about
115 for each sio port at 115200 bps).

The code for suspend/resume is derived from APM device driver.

Some people suggested the original code is somewhat buggy, but I'd
like to just move it from apm.c without any major changes for the
initial version.  This code should be refined later.

To use pmtimer to adjust time at resume time, add
	device	pmtimer
in your kernel config file, and add
	hint.pmtimer.0.at="isa"
in your device.hints
