block bits for 3.5-rc

Hi Linus,

As vacation is coming up, thought I'd better get rid of my pending changes in my for-linus branch for this iteration. It contains:

- Two patches for mtip32xx. Killing a non-compliant sysfs interface and moving it to debugfs, where it belongs.

- A few patches from Asias. Two legit bug fixes, and one killing an interface that is no longer in use.

- A patch from Jan, making the annoying partition ioctl warning a bit less annoying, by restricting it to !CAP_SYS_RAWIO only.

- Three bug fixes for drbd from Lars Ellenberg.

- A fix for an old regression for umem, it hasn't really worked since the plugging scheme was changed in 3.0.

- A few fixes from Tejun.

- A splice fix from Eric Dumazet, fixing an issue with pipe resizing.

Please pull!
