Fix -Wundef from compiling the amd64 LINT.

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386

2005-05-29T04:42:30+00:00

and amd64.  The optimization is a trivial on recent machines.

Use uint32_t instead of u_long when appropriate.

as these ioctl's aren't MD.  This also means they are installed in
/usr/include/dev/bktr now.  Also provide compatability wrappers for
where these headers lived in 4.x.

Use a mutex to synchronize the driver top and bottom halves instead of

using critcal_enter() and critical_exit() to attempt to replace spl*()
calls.  The critical section was calling selrecord(), which locks an
MTX_DEF mutex, which is not legal in a critical section.

- Implement selwakeuppri() which allows raising the priority of a

  thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.
