There was an issue in the data structure defined by megaraid driver
casuing "kernel unaligned access.." messages to be displayed during
IOCTL on IA64 platform.

The issue has been reported/fixed by Sakurai Hiroomi

With this patch, driver will protect data corruption created by
INQUIRY with EVPD request to megaraid controllers.  As specified in
the changelog, megaraid F/W already has fixed the issue and being
under process of release. Meanwhile, driver will protect the system
with this patch.

This patch contains
- a fix for 64-bit DMA capability check in megaraid_{mm,mbox} driver.
- includes changes (going back to 32-bit DMA mask if 64-bit DMA mask
failes) suggested by James with previous patch.
- addition of SATA 150-4/6 as commented by Vasily Averin.

With patch, the driver access PCIconfiguration space with dedicated
offset to read a signature. If the signature read, it means that the
controller has capability to handle 64-bit DMA.
Without this patch, the driver used to blindly claim 64-bit DMA
capability.
The issue has been reported by Vasily Averin [vvs@sw.ru].
Thank you Vasily for the reporting.

When abort failed, the driver gets reset handleer called.  In the reset
handler, driver calls 'scsi_done()' callback for same SCSI command packet
(struct scsi_cmnd) multiple times if there are multiple SCSI command packet
in the pend_list.  More over, if there are entry in the pend_lsit with
IOCTL packet associated, the driver returns it to wrong free_list so that,
in turn, the driver could end up with 'NULL pointer dereference..' during
I/O command building with incorrect resource.

Also, the patch contains several minor/cosmetic changes besides this.

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!
