cc46dff67f Work around a bug by adding struct tags. gcc-2.95 apparently gets the
check in the [basic.link] section of the C++ standard wrong.  gcc-2.7.2.3
apparently doesn't do the check, so the bug doesn't affect RELENG_3.

6c56727456 - Change fast interrupts on x86 to push a full interrupt frame and to
return through doreti to handle ast's.  This is necessary for the
  clock interrupts to work properly.
- Change the clock interrupts on the x86 to be fast instead of threaded.
  This is needed because both hardclock() and statclock() need to run in
  the context of the current process, not in a separate thread context.
- Kill the prevproc hack as it is no longer needed.
- We really need Giant when we call psignal(), but we don't want to block
  during the clock interrupt.  Instead, use two p_flag's in the proc struct
  to mark the current process as having a pending SIGVTALRM or a SIGPROF
  and let them be delivered during ast() when hardclock() has finished
  running.
- Remove CLKF_BASEPRI, which was #ifdef'd out on the x86 anyways.  It was
  broken on the x86 if it was turned on since cpl is gone.  It's only use
  was to bogusly run softclock() directly during hardclock() rather than
  scheduling an SWI.
- Remove the COM_LOCK simplelock and replace it with a clock_lock spin
  mutex.  Since the spin mutex already handles disabling/restoring
  interrupts appropriately, this also lets us axe all the *_intr() fu.
- Back out the hacks in the APIC_IO x86 cpu_initclocks() code to use
  temporary fast interrupts for the APIC trial.
- Add two new process flags P_ALRMPEND and P_PROFPEND to mark the pending
  signals in hardclock() that are to be delivered in ast().

1931cf940a - Heavyweight interrupt threads on the alpha for device I/O interrupts.
- Make softinterrupts (SWI's) almost completely MI, and divorce them
  completely from the x86 hardware interrupt code.
  - The ihandlers array is now gone.  Instead, there is a MI shandlers array
    that just contains SWI handlers.
  - Most of the former machine/ipl.h files have moved to a new sys/ipl.h.
- Stub out all the spl*() functions on all architectures.

2da5dbec3e Put on my nuclear-grade asbestos suit and cvs rm the old, broken, sound
drivers (again).  These drivers have not compiled for 5-6 months.
Now that the new sound code supports MIDI, the major reason we had for
reviving it is gone.  It is a far better investment polishing the new
midi code than trying to keep this on life support.  Come 5.0-REL, if
there are major shortcomings in the pcm sound driver then maybe we can
rethink this, but until then we should focus on pcm.

Remember, these have not been compilable since ~April-May this year.

2cf3496166 Fix the no-pci case of attaching isa, eisa and mca devices.
device_add_child() is meant to be called by the bus add_child method, not
to replace the bus add_child method.  We could have called nexus_add_device
directly too, that would have also worked.

7d03271452 Big mbuf subsystem diff #1: incorporate mutexes and fix things up somewhat
to accomodate the changes.

 Here's a list of things that have changed (I may have left out a few); for a
 relatively complete list, see http://people.freebsd.org/~bmilekic/mtx_journal

   * Remove old (once useful) mcluster code for MCLBYTES > PAGE_SIZE which
     nobody uses anymore. It was great while it lasted, but now we're moving
     onto bigger and better things (Approved by: wollman).

   * Practically re-wrote the allocation macros in sys/sys/mbuf.h to accomodate
     new allocations which grab the necessary lock.

   * Make sure that necessary mbstat variables are manipulated with
     corresponding atomic() routines.

   * Changed the "wait" routines, cleaned it up, made one routine that does
     the job.

   * Generalized MWAKEUP() macro. Got rid of m_retry and m_retryhdr, as they
     are now included in the generalized "wait" routines.

   * Sleep routines now use msleep().

   * Free lists have locks.

   * etc... probably other stuff I'm missing...

  Things to look out for and work on later:

   * find a better way to (dynamically) adjust EXT_COUNTERS

   * move necessity to recurse on a lock from drain routines by providing
     lock-free lower-level version of MFREE() (and possibly m_free()?).

   * checkout include of mutex.h in sys/sys/mbuf.h - probably violating
     general philosophy here.

   The code has been reviewed quite a bit, but problems may arise... please,
   don't panic! Send me Emails: bmilekic@freebsd.org

b6c8407840 Get out the roto-rooter and clean up the abuse of nexus ivars by the
i386/isa/pcibus.c.  This gets -current running again on multiple host->pci
machines after the most recent nexus commits.  I had discussed this with
Mike Smith, but ended up doing it slightly differently to what we
discussed as it turned out cleaner this way.  Mike was suggesting creating
a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(),
but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform
property, not a quirk of a given implementation.  This does use the ivar
methods but does so properly.  It also now prints the physical pci bus that
a host->pci bridge (pcib) corresponds to.
