Merge branch 'for-3.4/drivers' of git://git.kernel.dk/linux-block

Pull block driver bits from Jens Axboe:

 - A series of fixes for mtip32xx.  Most from Asai at Micron, but also
   one from Greg, getting rid of the dependency on PCIE_HOTPLUG.

 - A few bug fixes for xen-blkfront, and blkback.

 - A virtio-blk fix for Vivek, making resize actually work.

 - Two fixes from Stephen, making larger transfers possible on cciss.
   This is needed for tape drive support.
