these into using mutexes instead

James Bottomley 2a1e1379ba Merge by hand (conflicts in scsi_lib.c)
This merge is pretty extensive.  The conflict is over the new
req->retries parameter, so I had to change the prototype to
scsi_setup_blk_pc_cmnd() and the usage in sd, sr and st.

Mark Lord f0353301e6 [SCSI] Fix incorrect pointer in megaraid.c MODE_SENSE emulation
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.

Christoph Hellwig 238f9b063d [PATCH] fix megaraid.c locking
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

Testing by Burton Windle.

Christoph Hellwig cb0258a2fb [SCSI] megaraid (legacy): remove scsi_assign_lock usage
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.

James Bottomley 51c928c34f [SCSI] Legacy MegaRAID: Fix READ CAPACITY
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.

Greg Kroah-Hartman d18c3db58b [PATCH] PCI: make drivers use the pci shutdown callback instead of the driver core callback.
Now we can change the pci core to always set this pointer, as pci drivers
should use it, not the driver core callback.

Christoph Hellwig 8d115f845a [SCSI] remove scsi_cmnd->state
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!
