22e53424b2 kern_subr.c:
Added a new type to uiomove - "UIO_NOCOPY" which causes it to update
pointers and counts, but doesn't do any data copying. This is needed
for upcoming changes to the way that the vnode pager does its page
outs.
Added a new hash init function call "phashinit" that allocates and
initializes a prime number sized hash table.

vfs_cache.c:
Changed hashing algorithm to use the remainder of dividing by a prime
number to improve the distribution characteristcs. Uses new phashinit
function in kern_subr.c.

146e71662f Added -I/usrinclude to the tail end of the INCLUDES line. This hack
will cause kernel compiles to work even if the src/includes directory
doesn't exist but still do the 'Right Thing' and pull files from the
source tree if it does exist.

so that these ioctls can be handled by the calling layer(s).

cc865dd008 Off by one error in -MSG-START+0 was just Justin being tired -- revert to
old value.

Remove unnecessary check for active messages in setup SCB.  This same test
would also jump to p_mesgin_done which would "ACK" an extra time possibly
confusing the target.

Tell the kernel driver whenever we send an ABORT_TAG message.

b4fff2ae1a Patch from Greg Ansley:
In rare cases, when the filter specified accesses an multi-byte value that
is split across mbuf's, the value loaded is incorrect.  And if you are very
unlucky (like me) it will index off the end of the mbuf and into an
unallocated page and panic the system.

If you look at the code you will discover the the index *k* is added to
the pointer *cp* and the used AGAIN as a subscript.

bbf437ee54 Mask the call to ahc_attach with an splbio/splx pair. This allows us
to poll succesfully even if we are sharing the interrupt.

Register the interrupt handler before the attach.

This commit makes the 294x PCI shared interrupt compliant.  This has
been tested with an aic7870 motherboard controller and a 294x in the
same machine shareing an irq.

5743c01c3f Major overhaul of the aic7xxx driver:
- Report valid residual byte counts.  We actually pause the sequencer
	  when the residual is non-zero.  I thought about using DMA to do this,
	  bus sequencer program space is tight.

	- Fix embarassing off by one error in the computation of a 2's
	  compliment variable.  This was most likely the cause of the
	  many problems reported with the tagged queuing code.

	- Handle "MAX_SYNC" as a special case (ie we are the ones starting
	  the sync negotiation sequence).  This was done so that the target
	  scratch area can be initialed to 0 offset (asyncronous transfers)
	  safely.  The initialization to 0 (was 15) is necessary since in
	  some cases a Wide negotiation could run into problems if SCSIRATE
	  was set wrong and we went into data(in/out).

	- Trim the DMA routines a little by using some procedures.  Net
	  effect is more functionality with 3 less instructions after this
	  update.

	- Toggle the WIDEODD bit of the DFCNTRL whenever this is not the
	  last SG block.  It has no effect in the 8bit bus configuration,
	  but in the Wide configuration ensures that the overlap byte is
	  held in the SCSI block if the transfer is odd so it will end
	  up in the next SG (the correct behavior).

c5e0851d47 Major overhaul of the aic7xxx driver:
- catch the interrupt type (EDGE/LEVEL) before chip reset instead
	  of guessing the right type.

	- Add pause variable to the ahc struct to better handle the different
	  interrupt types and pausing the sequencer.

	- CLRINTSTAT -> CLRSCSIINT: This is a documented bit in the CLRINT
	  register in newer Adaptec documentation, so use their name for it.

	- Report valid residual byte counts.

	- Don't mess with the target scratch areas > id 8 on single, narrow,
	  channel devices.  The BIOS does a checksum of this area and can
	  flip out if we zero it out.

	- Initialize the sequencer FLAGS scratch ram variable in the single
	  channel devices to 0.  This was the cause of the annoying warning
	  where we would get a cmdcmplt the first time we did any type of
	  transfer negotiation with no valid scb.  It also fixes the problem
	  that looked like the INTSTAT register wasn't clearing fast enough.
	  This only showed up on 294x cards, not motherboard aic7870s.

	- Add the AHC_AIC7870 type and use it as the superset of aic7870
	  based controllers.

	- clear the sync offset section of the targ scratch area so that
	  we default to asyncronous transfers.  This was only a problem
	  for wide controllers because there was a scenario where the
	  offset wouldn't get updated before a data(out/in) phase would
	  occur.  This required some change in the sequencer code since we
	  were depending on this field to hold the rate to negotiate.

	- allow sync and wide negotiated commands to be tagged (the sequencer
	  now handles this properly).

496ccdde57 I and Seiji Murata <seiji@mt.cs.keio.ac.jp> contributed 3C589 PCMCIA
Etherlink III 'zp' on 2.0R, but it did not work with the -current.
Noriyuki Takahashi <hor@aecl.ntt.jp> san has fixed this bug.

Our alpha-testers are tested this driver with 3C589B-COMBO and
3C589B-TP.  And it works fine.

I also fixed a little about the use of ZP_DEBUG symbol and beautified
the awful Frankenstein-style indent :-) with "indent -c0 -nfc1 -i4".
