block driver bits for 3.7

Hi Linus,

Distilled down variant, the rest will pass over to 3.8. I pulled it into the for-linus branch I had waiting for a pull request as well, in case you are wondering why there are new entries in here too. This also got rid of two reverts and the ones of the mtip32xx patches that went in later in the 3.6 cycle, so the series looks a bit cleaner.

Please pull!
