1. Changes in Initialization to fix kdump failure.
Send SYNC command on loading.
This command clears the pending commands in the adapter
and re-initialize its internal RAID structure.
Without this change, megaraid driver either panics or fails to
initialize the adapter during kdump's second kernel boot
if there are pending commands or interrupts from other devices
sharing the same IRQ.
2. Authors email-id domain name changed from lsil.com to lsi.com.
Also modified the MODULE_AUTHOR to megaraidlinux@lsi.com

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!
