Martin Drab found that he could get aacraid timeouts with high load on his
controller / disk drive combinations. After some experimentation Mark
Salyzyn has come up with a patch to reduce the default max_sectors to
something that will keep the controller from being overloaded and will
eliminate the timeout issues.

Drivers need not implement a hook that returns FAILED, and does nothing
else, since the SCSI midlayer code will do that for us.

New code from the Adaptec driver. Performance enhancement for newer
adapters. I hope that this isn't too big for a single patch. I believe
that other than the few small cleanups mentioned, that the changes are
all related.
- Added Variable FIB size negotiation for new adapters.
- Added support to maximize scatter gather tables and thus permit
requests larger than 64KB/each.
- Limit Scatter Gather to 34 elements for ROMB platforms.
- aac_printf is only enabled with AAC_QUIRK_34SG
- Large FIB ioctl support
- some minor cleanup
Passes sparse check.
I have tested it on x86 and ppc64 machines.

This fixes an error on the device open code that allows a non-existent
device to be opened causing later panic problems.

This patch addresses the sparse -Wbitwise warnings that Christoph wanted
me to eliminate. This mostly consisted of making data structure
elements of hardware associated structures the __le* equivalent.
Although there were a couple places where there was mixing of cpu and le
variable math. These changes have been tested on both an x86 and ppc
machine running bonnie++. The usage of the LE32_ALL_ONES macro has been
eliminated.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
