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
