e499ed6f86 Fix a problem when creating a new kernel thread. In some cases, aio_read
or aio_write can return the pid of the new thread.  This is due to the
way that return values from system calls being passed by side-effect in
the proc structure now.  This commit fixes the problem with aio_read and
aio_write.

84af4da65a Finish up the vast majority of the AIO/LIO functionality. Proper signal
support was missing in the previous version of the AIO code.  More
tunables added, and very efficient support for VCHR files has been added.
Kernel threads are not used for VCHR files, all work for such files is
done for the requesting process directly.  Some attempt has been made to
charge the requesting process for resource utilization, but more work
is needed.  aio_fsync is still missing (but the original fsync system
call can be used for now.)  aio_cancel is essentially a noop, but that
is okay per POSIX.  More aio_cancel functionality can be added later,
if it is found to be needed.

The functions implemented include:
	aio_read, aio_write, lio_listio, aio_error, aio_return,
	aio_cancel, aio_suspend.

The code has been implemented to support the POSIX spec 1003.1b
(formerly known as POSIX 1003.4 spec) features of the above.  The
async I/O features are truly async, with the VCHR mode of operation
being essentially the same as physio (for appropriate files) for
maximum efficiency.  This code also supports the signal capability,
is highly tunable, allowing management of resource usage, and
has been written to allow a per process usage quota.

Both the O'Reilly POSIX.4 book and the actual POSIX 1003.1b document
were the reference specs used.  Any filedescriptor can be used with
these new system calls.  I know of no exceptions where these
system calls will not work.  (TTY's will also probably work.)

61ca849927 From the author:
Here are the remanding changes required to support the Ensoniq
Soundscape using FreeBSD 3.0-current.

Notes:

  1) ad1848_init already has code to detect if DMA_DUPLEX should
     be set so it is not necessary (and is in fact a mistake) to
     hard code setting it.  Not all soundcards (i.e. the current
     sscape driver) are capable of using DMA_DUPLEX.

  2) The other changes are hopefully self explanatory.  Feel free
     to let me know if you need additional information.

043e37feab Added a sysctl (machdep.cputime_clock) to select the clock used by
"high resolution" profiling.  The available clocks are:
- the i8254 clock
- on non-SMP i586's and i686's: the TSC
- on systems with I586_PMC_GUPROF configured, and PERFMON configured
  and available: all the performance counters.
This is unfinshed (there are problems with locking out the PERFMON
device driver, and with losing calibration after switching the clock),
but better than static configuration or writing to kmem.

Changed ifdefs to avoid generating code for non-working option
combinations.

5b76055a53 Fixed overflow in ufs_getblns(). For ufs on systems with 32-bit ints,
triple indirect blocks only worked for block sizes of 4K, since
MNINDIR(ump)**3 overflows for larger block sizes (e.g.,
(8192/4)**3 = 2**33 > INT_MAX).  This fix is not the obvious one of
changing some types to 64 bits.  It rearranges the code to avoid some
unnecessary 64-bit calculations.
