Justin T. Gibbs 333f04d935 Correct/Simplify ignore wide residue message handling
aic79xx.c:
	In ahd_handle_ign_wide_residue():
	o Use SCB_XFERLEN_ODD SCB field to determine transfer
	  "oddness" rather than the DATA_COUNT_ODD logic.
	  SCB_XFERLEN_ODD is toggled on every ignore wide
	  residue message so that multiple ignore wide residue
	  messages for the same transaction are properly supported.
	o If the sg list has been exausted, the sequencer
	  doesn't bother to update the residual data count
	  since it is known to be zero.  Perform the zeroing
	  manually before calculating the remaining data count.
	o Use multibyte in/out macros instead of shifting/masking
	  by hand.

aic79xx_inline.h:
	In ahd_setup_scb_common(), setup the SCB_XFERLEN_ODD field.

aic79xx.reg:
	Use the SCB_TASK_ATTRIBUTE field as a bit field in the
	non-packetized case.  We currently only define one bit,
	SCB_XFERLEN_ODD.

	Remove the ODD_SEG bit field that was used to carry the odd
	transfer length information through the SG cache.  This
	is obviated by SCB_XFERLEN_ODD field.

	Remove the DATA_COUNT_ODD scratch ram byte that was used
	dynamicaly compute data transfer oddness.  This is obviated
	by SCB_XFERLEN_ODD field.

aic79xx.seq:
	Remove all updates to the DATA_COUNT_ODD scratch ram field.
	Remove all uses of ODD_SEG.  These two save quite a few
	sequencer instructions.

	Use SCB_XFERLEN_ODD to validate the end of transfer
	ignore wide residue message case.

This is the top level of the FreeBSD source directory.  This file
was last revised on:
$FreeBSD$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel, the kernel-modules and the contents of /etc.  The
``buildkernel'' and ``installkernel'' targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process, documentation
for which can be found at:
   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
And in the config(8) man page.
Note: If you want to build and install the kernel with the
``buildkernel'' and ``installkernel'' targets, you might need to build
world before.  More information is available in the handbook.

The sample kernel configuration files reside in the sys/<arch>/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file NOTES contains entries and documentation for all possible
devices, not just those commonly used.  It is the successor of the ancient
LINT file, but in contrast to LINT, it is not buildable as a kernel but a
pure reference and documentation file.
