block driver bits for 3.4

Hi Linus,

On top of the core bits, but this time nothing in the drivers branch depends on any core changes.

- 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.

Please pull.
