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).

87de370376 gcc knows that savectx() is potentially a setjmp style dual-return
function which may lead to stack lossage and clobbered variables.
This isn't the case here, but there is no way to tell gcc that.

Work around this in a kinda bizzare way, but it shuts gcc up.

3e755f76d1 Make it possible to pass boot()'s flags to shutdown_nice() so that the
kernel can instigate an orderly shutdown but still determine the form of
that shutdown.  Make it possible eg. to cleanly shutdown and power off the
system under ACPI when the power button is pressed.

9626b608de Separate the struct bio related stuff out of <sys/buf.h> into
<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.

9959b1a882 Improved DDB_UNATTENDED behaviour. From the submitter:
There's something that's been bugging me for a while, so I decided to fix it.
FreeBSD now will DTRT WRT DDB and DDB_UNATTENDED (!debugger_on_panic), at least
in my opinion. The behavior change is such that:

	1. Nothing changes when debugger_on_panic != 0.
	2. When DDB_UNATTENDED (!debugger_on_panic), if a panic occurs, the
		machine will reboot. Also, if a trap occurs, the machine will
		panic and reboot, unlike how it broke to DDB before. HOWEVER,
		a trap inside DDB will not cause a panic, allowing full use
		of DDB without having to worry about the machine being stuck
		at a DDB prompt if something goes wrong during the day.
		Patches for this behavior follow my signature, and it would
		be a boon to anyone (like me) who uses DDB_UNATTENDED, but
		actually wants the machine to panic on a trap (otherwise,
		what's the use, if the machine causes a fatal trap rather than
		a true panic, of debugger_on_panic?). The changes cause no
		adverse behavior, but do involve two symbols becoming global

d02d6d040a Don't count non-local dirty buffers as outstanding when shutting down.
This avoids the fsck-on-reboot symptoms if you're shutting down with a
hung or unreachable NFS server mounted.  Also remove non-local
filesystems from the mount list to prevent the system hanging when it tries
to unmount them (for the same reason).

Drew points out that there's a good argument for forcibly removing all
"non syncable" filesystems from the mount list (eg. NFS mounts, disks
that aren't responding, etc.) as this then allows you to sync and
cleanly unmount their parents.  No such change is included in this
patch.

b322fb5d76 Backed out previous commit. It is invalid to call d_ioctl() on
possibly non-open devices, and we don't want to restrict dumping
to swap devices anwyay.  It is especially invalid to call d_ioctl()
in non-process context for panics.  d_psize() can be called on
non-open devices, at least on non-SLICED ones that support d_dump(),
and setdumpdev() has depended on this for a long time although it
is probably wrong, but even d_psize() can't be called in non-process
context - that's why dumpsys() depends on previously computed values
although these values may be stale.  The historical restriction to
devices with dkpart(dev) == SWAP_PART should go away.

This eliminates a lot of #ifdef SMP type code.  Things like _curproc reside
in a data page that is unique on each cpu, eliminating the expensive macros
like:    #define curproc (SMPcurproc[cpunumber()])

There are some unresolved bootstrap and address space sharing issues at
present, but Steve is waiting on this for other work.  There is still some
strictly temporary code present that isn't exactly pretty.

This is part of a larger change that has run into some bumps, this part is
standalone so it should be safe.  The temporary code goes away when the
full idle cpu support is finished.

fc0b1dbf68 Don't use __dead in the kernel. It was an obfuscation for gcc >= 2.5
and a no-op for gcc >= 2.6.

e0d898b48e Some cleanups to the callout lists recently added.
note that at_shutdown has a new parameter to indicate When
during a shutdown the callout should be made. also
add a RB_POWEROFF flag to reboot "howto" parameter..
tells the reboot code in our at_shutdown module to turn off the UPS
and kill the power. bound to be useful eventually on laptops

ad4240fec4 move all functions related to shutting down to one file
called kern_shutdown.c

note: I couldn't see anything machine dependant in the
functions boot() and dumpsys() which were in machdep.c
I have left a prototype for cpu_boot() which would go in
machdep.c, but I have nothing to put in it. Iexpect others will
let me know in no uncertain ways that this or that  is machine dependant
and should be there, but I'll way for that to happen.. :)

I haven't actually taken the functions OUT of machdep
or anywhere else yet.. I'm checking in this file so others can have a look
at it and comment. SO PLEASE DO COMMENT!

I am also (in another checkin) addinf a man(9) page for the new
at_shotdown().. er freudian slip there.. at_shutdown() call
so have a look at that (and at_exit and at_fork as well)
and feed me comments..

I'll heck in the changes to make these (shutdown) changes active tomorrow
if no-one objects too strongly..
