fe01c653ba Consider that the chipset may be in ECP mode (from BIOS settings) 
even if mode PS/2 is forced with bootflags. As a matter of fact,
chipsets needs some extra configuration for accessing PS/2 mode
from ECP. The current patch is only relevant for generic chipsets
since specific code is supposed to deal with this during detection.

af00dc8eef - Change fork_exit() to take a pointer to a trapframe as its 3rd argument 
instead of a trapframe directly.  (Requested by bde.)
- Convert the alpha switch_trampoline to call fork_exit() and use the MI
  fork_return() instead of child_return().
- Axe child_return().

cf8988088c Oops, when converting if (foo) panic() to a KASSERT(), you have to invert 
the test case.

c5cc2f8e26 Argh, I didn't get this test right when I converted it. Break this up 
into two separate if's instead of nested if's.  Also, reorder things
slightly to avoid unnecessary mutex operations.

9e1a5e2c5b - Catch up to proc flag changes. 
- Proc locking in a few places.
- faultin() now must be called with the proc lock held.
- Split up swappable() into a couple of tests so that it can be locke in
  swapout_procs().
- Use queue macros.

2a1df40436 - Catch up to proc flag changes.

  held and is not recursed.  Note that the STOPEVENT() macro obtains
  the proc lock when calling this function.

233d6de215 - Don't use a union and fun tricks to shave one extra pointer off of struct 
mtx right now as it makes debugging harder.  When we are in optimizing
  mode, we can revisit this.
- Fix the KTR trace messages to use %p rather than 0x%p to avoid duplicate
  0x's in KTR output.
- During witness_fixup, release Giant so that witness doesn't get confused.
  Also, grab all_mtx while walking the list of mutexes.
- Remove w_sleep and w_recurse.  Instead, perform checks on mutexes using
  the mutex's mtx_flags field.
- Allow debug.witness_ddb and debug.witness_skipspin to be set from the
  loader.
- Add Giant to the front of existing order_list entries to help ensure
  Giant is always first.
- Add an order entry for the various proc locks.  Note that this only
  helps keep proc in order mostly as the allproc and proctree mutexes are
  only obtained during a lockmgr operation on the specified mutex.
