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!

1AACRAID Driver for Linux (take two)
2
3Introduction
4-------------------------
5The aacraid driver adds support for Adaptec (http://www.adaptec.com)
6RAID controllers. This is a major rewrite from the original
7Adaptec supplied driver. It has signficantly cleaned up both the code
8and the running binary size (the module is less than half the size of
9the original).

41Alan Cox <alan@redhat.com>
42Christoph Hellwig <hch@infradead.org> (updates for new-style PCI probing and SCSI host registration,
43 small cleanups/fixes)
44Matt Domsch <matt_domsch@dell.com> (revision ioctl, adapter messages)
45Deanna Bonds (non-DASD support, PAE fibs and 64 bit, added new adaptec controllers
46 added new ioctls, changed scsi interface to use new error handler,
47 increased the number of fibs and outstanding commands to a container)
48
49 (fixed 64bit and 64G memory model, changed confusing naming convention
50 where fibs that go to the hardware are consistently called hw_fibs and
51 not just fibs like the name of the driver tracking structure)
52Mark Salyzyn <Mark_Salyzyn@adaptec.com> Fixed panic issues and added some new product ids for upcoming hbas.

61Also note this is very different to Brian's original driver
62so don't expect him to support it.
63Adaptec does support this driver. Contact either tech support or Mark Salyzyn.
