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

Pull block fixes from Jens Axboe:
 "A small collection of driver fixes/updates and a core fix for 3.6.  It
  contains:

   - Bug fixes for mtip32xx, and support for new hardware (just addition
     of IDs).  They have been queued up for 3.7 for a few weeks as well.

   - rate-limit a failing command error message in block core.

   - A fix for an old cciss bug from Stephen.

   - Prevent overflow of partition count from Alan."

* 'for-linus' of git://git.kernel.dk/linux-block:
  cciss: fix handling of protocol error
  blk: add an upper sanity check on partition adding
  mtip32xx: fix user_buffer check in exec_drive_command
  mtip32xx: Remove dead code
  mtip32xx: Change printk to pr_xxxx
  mtip32xx: Proper reporting of write protect status on big-endian
  mtip32xx: Increase timeout for standby command
  mtip32xx: Handle NCQ commands during the security locked state
  mtip32xx: Add support for new devices
  block: rate-limit the error message from failing commands
