8ab109d131 Remove count for NSIO. The only places it was used it were incorrect.
(alpha-gdbstub.c got sync'ed up a bit with the i386 version)

1467a651ab Convert apm from a bogus 'count' into a plain option. Clean out some
other cruft from the files.alpha and files.ia64 that were related to this.

78531822bb Don't build the ACPI CA debugger unless the ACPI_DEBUG option is present.
Only build the IA32 support on i386.  Build the IA64 support on IA64.

36412d79b4 - Make the mutex code almost completely machine independent. This greatly
reducues the maintenance load for the mutex code.  The only MD portions
  of the mutex code are in machine/mutex.h now, which include the assembly
  macros for handling mutexes as well as optionally overriding the mutex
  micro-operations.  For example, we use optimized micro-ops on the x86
  platform #ifndef I386_CPU.
- Change the behavior of the SMP_DEBUG kernel option.  In the new code,
  mtx_assert() only depends on INVARIANTS, allowing other kernel developers
  to have working mutex assertiions without having to include all of the
  mutex debugging code.  The SMP_DEBUG kernel option has been renamed to
  MUTEX_DEBUG and now just controls extra mutex debugging code.
- Abolish the ugly mtx_f hack.  Instead, we dynamically allocate
  seperate mtx_debug structures on the fly in mtx_init, except for mutexes
  that are initiated very early in the boot process.   These mutexes
  are declared using a special MUTEX_DECLARE() macro, and use a new
  flag MTX_COLD when calling mtx_init.  This is still somewhat hackish,
  but it is less evil than the mtx_f filler struct, and the mtx struct is
  now the same size with and without mutex debugging code.
- Add some micro-micro-operation macros for doing the actual atomic
  operations on the mutex mtx_lock field to make it easier for other archs
  to override/optimize mutex ops if needed.  These new tiny ops also clean
  up the code in some places by replacing long atomic operation function
  calls that spanned 2-3 lines with a short 1-line macro call.
- Don't call mi_switch() from mtx_enter_hard() when we block while trying
  to obtain a sleep mutex.  Calling mi_switch() would bogusly release
  Giant before switching to the next process.  Instead, inline most of the
  code from mi_switch() in the mtx_enter_hard() function.  Note that when
  we finally kill Giant we can back this out and go back to calling
  mi_switch().

8d9761debf Next round of fixes to the ia64 code. This includes simulated clock and
disk drivers along with a load of fixes to context switching, fork
handling and a load of other stuff I can't remember now. This takes us as
far as start_init() before it dies. I guess now I will have to finish off
the VM system and syscall handling :-).

a6bc3edb3b Move the ata/atapi files to the common area. They were the same on all
platforms.

While here, work around a strange quirk in config(8) that I do not yet
understand.  Rearrange which atapi* files have 'optional' vs. 'count'
so that you can have atapifd without atapicd.  The only difference should
be that this works instead of having a link error because atapi-all.o got
left out of the kernel.

1ebcad5720 This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
