aac.c:
Re-arrange the interrupt handler to optimize the common case of
the adapter interrupting us because one or more commands are complete,
and do a read across the pci bus to ensure that all posted status
writes are flushed. This should close a race that could cause command
completion interrupts to be lost.
Follow the spec a bit closer when filling out command structures.
Enable the Fast Response feature to eliminate the need for the card
to DMA successfull command completions back into host memory.
Tell the controller how much physical memory we have. Without this
there was a chance that our DMA regions would collide with the
memory window used by the cache on the controller. The result would
be massive data corruption. This seemed to mainly affect systems with
>2GB of memory.
Fix a few whitespace problems.
aac_debug.c:
Add an extra diagnostic when printing out commands.
aac_disk.c:
Add extra sanity checks.
aacreg.h:
Prepare for making this 64-bit clean by reducing the use of enumeration
types in structures.
Many thanks to Justin Gibbs for helping track these down.
that crept in recently. GCC will optimize the divides and multiplies for us.

- In Create_Chunk_DWIM(), if there is a freebsd chunk that has no
children chunks, then trying to add a child part chunk will fail even
though there is free space. Handle this special case by adding an
unused chunk the full size of the freebsd chunk as a child of the
freebsd chunk before adding the new part chunk. This situation can
happen when changing the type of an existing slice to be a FreeBSD
slice type or when installing onto a blank disk on Alpha (which has
no slices.)
