Basically, the reason most people haven't seen this is
most likely related to the low usage of MCHTYPE.
Pointed out and suggested a fix by: Boris Popov (bp) - thanks!
Taking over the sector following the MBR causes problems on some
machines, and the actual gains are fairly small in terms of how
the space is presently used.
Since we need a number of further features (eg. handling extended
partitions) that can't be readily accommodated in the basic boot0
design anyway, rather choose to implement the additional stuff
separately and concentrate on compatibility rather than features
here.

Replace shared lock on vnode with exclusive one. It shouldn't impact
perfomance as NCP protocol doesn't support outstanding requests.
Do not hold simple lock on vnode for long period of time.
Add functionality to the nwfs_print() routine.
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.
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.
- If resource which was allocated for pcic was
requested via this ioctl, bus_alloc_resource
would be succeeded and that resource was
returned as free resource. So check whether
requested resource was used for pcic or not
before bus_alloc_resource test.
- merge SYS_RES_IRQ routine into other SYS_RES_*
routine and clean up.

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.

that it's enabled in acpireg.h only if DIAGNOSTIC option is specified.
ACPICA OSD functions will be compiled in machine/acpi_machdep.c again
tentatively (if DIAGNOSTIC option is specified).
# Should we have acpica_osd.c ?
avoid power on again problem after acpi_soft_off() calling.
- Implement SleepOp/StallOp in AML interpreter. Also provide ACPICA
compatibility.
- Minor changes on __inline function declaration in acpica_osd.h
(obtained from NetBSD porting).
- Move all register I/O into acpi_io.c
- Move event handling into acpi_event.c
- Reorganise headers into acpivar/acpireg/acpiio
- Move find-RSDT and find-ACPI-owned-memory into acpi_machdep
- Allocate all resources (except those detailed only by AML)
as real resources. Add infrastructure that will make adding
resource support to AML code easy.
- Remove all ACPI #ifdefs in non-ACPI code
- Removed unnecessary includes
- Minor style and commenting fixes

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,

not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
