6aa22e7189 - Add a new process flag P_NOLOAD that marks a process that should be

c1fd1180ab Factorize, reorganize, and move code around.
The boot-conf and boot code had various bugs, and some of it was big,
ugly, unwieldy, and, sometimes, plain incorrect. I'm just about
completely replaced these ugly parts with something much more manageable.

Minor changes were made to the well-factorized parts of it, to accomodate
the new code.

Of note:

	* make sure boot-conf has the exact same behavior wrt boot order
as start.

	* Correct both boot and boot-conf so they'll work correctly when
compiled in, as they both had some bugs, minor and major.

	* Remove all the crud from loader.4th back into support.4th, for
the first time since boot-conf was first improved. Hurray!

I'm fairly satisfied with the code at this time. Time to see about those
man pages...

43d09251f2 Check to see if we actually have an interrupt descriptor and an interrupt
thread for each interrupt that comes in.  If we don't, log the event and
return immediately for a hardware interrupt.  For a softinterrupt, panic
instead.

ee51abd060 Add Timer device driver for power management events.
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

7013b83225 - Remove the inthand2_t type and use the equivalent driver_intr_t type from
newbus for referencing device interrupt handlers.
- Move the 'struct intrec' type which describes interrupt sources into
  sys/interrupt.h instead of making it just be a x86 structure.
- Don't create 'ithd' and 'intrec' typedefs, instead, just use 'struct ithd'
  and 'struct intrec'
- Move the code to translate new-bus interrupt flags into an interrupt thread
  priority out of the x86 nexus code and into a MI ithread_priority()
  function in sys/kern/kern_intr.c.
- Remove now-uneeded x86-specific headers from sys/dev/ata/ata-all.c and
  sys/pci/pci_compat.c.

2eb0243bb6 - Fix spinlock exits to properly handle the recursion count and only
re-enable interrupts when actually releasing the lock.
- Bring across some fixes to propagate_priority from the x86 code.
  (It still doesn't work properly, however.)
- Use the SMTX state when putting a process that blocks on a mutex to sleep.
- Use mi_switch instead of cpu_switch so that accounting works properly as
  well as other things.
- Bring across DDB protection of the spinlock timeout panic which is useful
  in a multiple CPU system when 1 CPU enters the debugger holding the
  sched_lock so that the other CPU doesn't panic as well resulting in all
  sorts of fun things.
- Bring across various other small changes in format strings and comments
  to sync up with the x86 code.

1f9f76e138 Be more careful about cleaning up the stack after function calls early
in the boot.  The cleanup must be done in one of the few ways that
db_numargs() understands, so that early backtraces in ddb don't underrun
the stack.  The underruns caused reboots a few years ago when there
was an unmapped page above the stack (trapping to abort the command
doesn't work early).

Cleaned up some nearby code.

4df37ee8ee Fixed hang on booting with -d. mtx_enter() was called on an uninitialized
lock.  The quick fix in trap.c was not quite the version tested and had no
effect; back it out.

filesystem may hold the lock. Otherwise unavoidable deadlock will occur.
This shouldn't have any side effects as long as we hold vfs lock.
