102d19a473 Implement SCB paging which allows up to 255 active commands on aic7770 
(Rev E or greater), aic7850, aic7860, aic7870, and aic7880 controllers.
SCB paging is enabled with the option "AHC_SCBPAGING_ENABLE".  Full
comments on the algorithm are at the top of i386/scsi/aic7xxx.c.

options "AHC_TAGENABLE" and "AHC_QUEUE_FULL" have been removed.  The
default is 4 tags without SCB paging, 8 with.

Clear the SCSIRSTI bit after throwing a bus reset.  Some cards seem to get
confused otherwise.

Handle SCSIRSTI interrupts before checking to see if there is a valid
SCB in use since this can happen. (Clears PR# i386/1123)

Clean up the way we determine the number of SCBs on the card
(courtesy of Dan Eischen).

Guard against attempts to negotiate wide to a narrow controller.

Fix some comments.

Update my copyrights.

0513ce7f75 Use PCB_SAVEFPU_SIZE instead of a too-small size in savectx(). This 
bug only affected FPU emulators.  It might have caused bogus FPU states
in core dumps and in the child pcb after a fork.  Emulated FPU states
in core dumps don't work for other reasons, and the child FPU state
is reinitialized by exec, so the problem might not have caused any
noticeable affects.

Cleaned up #includes.

this document will be removed, and it's information moved to the handbook.

1dce4e5d60 Add a lock for DMA Channels to prevent two devices from using the same DMA 
channel at the same time.  The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.

Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed
