Merge branch 'for-3.9/drivers' of git://git.kernel.dk/linux-block

Pull block driver bits from Jens Axboe:
 "After the block IO core bits are in, please grab the driver updates
  from below as well.  It contains:

   - Fix ancient regression in dac960.  Nobody must be using that
     anymore...

   - Some good fixes from Guo Ghao for loop, fixing both potential
     oopses and deadlocks.

   - Improve mtip32xx for NUMA systems, by being a bit more clever in
     distributing work.

   - Add IBM RamSan 70/80 driver.  A second round of fixes for that is
     pending, that will come in through for-linus during the 3.9 cycle
     as per usual.

   - A few xen-blk{back,front} fixes from Konrad and Roger.

   - Other minor fixes and improvements."
