Attached patch fixes problem that cause kobject_register failure
during loading.  Kobject_register would fail when there are more than
1 module with same module name.  This patch will change module name of
megaraid_legacy from 'megaraid' to 'megaraid_legacy'.

the scsi layer is using semaphores in a mutex way, this patch converts
these into using mutexes instead

This patch fixes
	- PCI ID overlap issue
	- node name changed to 'megaraid_legacy'
I hope this patch addresses concerns brought by Daniel Drake.

The SCSI megaraid drive goes to great effort to kmap
the scatterlist buffer (if used), but then uses the
wrong pointer when copying to it afterward.

This fixes locking in megaraid.c, namely:

 (1) make sure megaraid_queue release the adapter lock by changing the
     code to have a single return
 (2) remove the errornous scsi_assign_lock call

just take the adapter lock in megaraid_queue.  Additional benefit is
that we can get rid of the awkward conditional locking in
mega_internal_command.

Some Legacy megaraid cards can't actually cope with the scatter/gather
version of the READ CAPACITY command (which is what we now send them
since altering all SCSI internal I/O to go via the block layer).  Fix
this (and a few other broken megaraid driver assumptions) by sending
the non-sg version of the command if the sg list only has a single
element.

Now we can change the pci core to always set this pointer, as pci drivers
should use it, not the driver core callback.

We never look at it except for the old megaraid driver that abuses it
for sending internal commands.  That usage can be fixed easily because
those internal commands are single-threaded by a mutex and we can easily
use a completion there.

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!
