1931cf940a - Heavyweight interrupt threads on the alpha for device I/O interrupts.
- Make softinterrupts (SWI's) almost completely MI, and divorce them
  completely from the x86 hardware interrupt code.
  - The ihandlers array is now gone.  Instead, there is a MI shandlers array
    that just contains SWI handlers.
  - Most of the former machine/ipl.h files have moved to a new sys/ipl.h.
- Stub out all the spl*() functions on all architectures.

IBM's DPTA and DTLA series of drives (no other disk vendors are known
to support this) on non-Promise controllers (promise controllers lockup
when given the tagged queuing specific commands).

0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

071e6e581e Add support for accessing individual tracks on a CD.
This is done by misusing the device minor a bit to encode the
track no there.

So to read track #4 just use /dev/acdNt4 where N is the device #.

The driver no automatically sets the blocksize (sectorsize) to
what the track is set to in the TOC.

This has the nice effect that you can now rip audioi tracks
by simply doing:

dd if=/dev/acdNt2 of=audiotrack2.raw bs=2352

it cant be much simpler than that :)

NOTE: the original acdNa & acdNc device still work as usual,
except the blocksize is set according to track0.

0385347c1a Implement an optimization of the VM<->pmap API. Pass vm_page_t's directly
to various pmap_*() functions instead of looking up the physical address
and passing that.  In many cases, the first thing the pmap code was doing
was going to a lot of trouble to get back the original vm_page_t, or
it's shadow pv_table entry.

Inspired by: John Dyson's 1998 patches.

Also:
Eliminate pv_table as a seperate thing and build it into a machine
dependent part of vm_page_t.  This eliminates having a seperate set of
structions that shadow each other in a 1:1 fashion that we often went to
a lot of trouble to translate from one to the other. (see above)
This happens to save 4 bytes of physical memory for each page in the
system.  (8 bytes on the Alpha).

Eliminate the use of the phys_avail[] array to determine if a page is
managed (ie: it has pv_entries etc).  Store this information in a flag.
Things like device_pager set it because they create vm_page_t's on the
fly that do not have pv_entries.  This makes it easier to "unmanage" a
page of physical memory (this will be taken advantage of in subsequent
commits).

Add a function to add a new page to the freelist.  This could be used
for reclaiming the previously wasted pages left over from preloaded
loader(8) files.

af5bd99e9a Fix for the HP burners (and possibly other broken drives to)
that fails to proberly close the disk.
The problem seems to be that the HP burners sometimes return
ready when they actually are not, the solution is to not use
immediate mode on the closing commands. This is suboptimal
for real burners, in that they now hog the ATA bus for possibly
minutes, where its really not nessesary, *sigh*.

c244d2de43 Move B_ERROR flag to b_ioflags and call it BIO_ERROR.
(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.

21144e3bf1 Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new
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.

8048917432 Backout the previous fix, it is _not_ that easy too fix.
Leave it as is for 4.0 the real solution comes later.
