[GIT PULL] Block bits for 3.8 final

[GIT PULL] Block bits for 3.8 final

[Jens Axboe]

Hi Linus,

I've got a few bits pending for 3.8 final, that I better get sent out.
It's all been sitting for a while, I consider it safe.

It contains:

- Two bug fixes for mtip32xx, fixing a driver hang and a crash.

- A few-liner protocol error fix for drbd.

- A few fixes for the xen block front/back driver, fixing a potential
  data corruption issue.

- A race fix for disk_clear_events(), causing spurious warnings. Out of
  the Chrome OS base.

- A deadlock fix for disk_clear_events(), moving it to the a unfreezable
  workqueue. Also from the Chrome OS base.

Please pull!
