a138e28335 Discard extra status information if -1. This has been breaking the
PS/2 mode for ZIP+ drives for a long time. Thanks Jonathon.

c264e80fb7 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.

45ece682fd - Doh, lock faultin() with proc lock in scheduler().
- Lock p_swtime with sched_lock in scheduler() as well.

2a36ec35ae - 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().

c2e9063250 Oops, when converting if (foo) panic() to a KASSERT(), you have to invert
the test case.

69b4045657 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.

5074aecd6c - 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.

3897ca7c61 - Catch up to proc flag changes.
- Update stopevent() to assert that the proc lock is held when it is
  held and is not recursed.  Note that the STOPEVENT() macro obtains
  the proc lock when calling this function.

8484de7555 - 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.
