  Modified files:
    sys/alpha/alpha      synch_machdep.c 
  Log:
  - 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.
