return the last value returned by a nested method call. This violates
the ACPI spec, but is implemented by the Microsoft interpreter, and thus
vendors can (and do) get away with it.
Intel's stance is that this is illegal and should not be supported.
As they put it, however, we have to live in the real world. So go ahead
and implement it.

- Set debugger options for kernel build
- Define some missing functions
- Bring in GCC defines
- Disable the 'wbinvd' macro as it conflicts with our inline
- AcpiGetProcessorID (fetch the ACPI processor ID for a given ACPI_HANDLE)
- AcpiSetSystemSleepState (set the Sx sleeping state, proposed by Intel
but not actually implemented)
o Remove bogus "spurious interrupt" message.
o Ring buffer head and avail were incorrectly calculated.
o Fix fragment count.
o Fix ring entry for single station, default to 16Mbit.
o Don't complain about long frames.
<sys/bio.h>.
<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.
Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.
Still a few bogus uses of struct buf to track down.

Exceptions:
Vinum untouched. This means that it cannot be compiled.
Greg Lehey is on the case.
CCD not converted yet, casts to struct buf (still safe)
atapi-cd casts to struct buf to examine B_PHYS
(Much of this done by script)
Move B_ORDERED flag to b_ioflags and call it BIO_ORDERED.
Move b_pblkno and b_iodone_chain to struct bio while we transition, they
will be obsoleted once bio structs chain/stack.
Add bio_queue field for struct bio aware disksort.
Address a lot of stylistic issues brought up by bde.
field in struct buf: b_iocmd. The b_iocmd is enforced to have
exactly one bit set.
B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.
Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.
Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue. It is likely to write on your disk
where it should have been reading.
This change is a step in the direction towards a stackable BIO capability.
A lot of this patch were machine generated (Thanks to style(9) compliance!)
Vinum users: Greg has not had time to test this yet, be careful.
4/16/100 -> 100/16/4 so that it matches all of the others.
o Since we went to all the trouble of getting the correct
working memory size actually use it.

new-bus Olicom driver, previously known as "ol". The new
driver unfortunately does not support ISA cards yet.
o Update the microcode files, interface library and include files
to the latest PowerMACH works version. Force even byte alignment
of adapter microcode.
o Roll in some of the patches from Nikolai Saoukh <nms@ethereal.ru>.
The same goes for CD drivers and tape drivers. In systems with mixed IDE
and SCSI, devices in the same priority class will be sorted in attach
order.
Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of
drivers have been modified to use that priority.
This includes the necessary changes to all drivers, except the ATA drivers.
Soren will modify those separately.
This does not include and does not require any change in the devstat
version number, since no known userland applications use the priority
enumerations.
