[GIT PULL] block fixes for 3.3-rc

[GIT PULL] block fixes for 3.3-rc

[Jens Axboe]

Hi Linus,

Time to push off some of the pending items. I really wanted to wait until
we had the regression nailed, but alas it's not quite there yet. But I'm
very confident that it's "just" a missing expire on exit, so fix from
Tejun should be fairly trivial. I'm headed out for a week on the slopes.

- Killing the barrier part of mtip32xx. It doesn't really support
  barriers, and it doesn't need them (writes are fully ordered).

- A few fixes from Dan Carpenter, preventing overflows of integer
  multiplication.

- A fixup for loop, fixing a previous commit that didn't quite solve the
  partial read problem from Dave Young.

- A bio integer overflow fix from Kent Overstreet.

- Improvement/fix of the door "keep locked" part of the cdrom shared
  code from Paolo Benzini.

- A few cfq fixes from Shaohua Li.

- A fix for bsg sysfs warning when removing a file it did not create
  from Stanislaw Gruszka.

- Two fixes for floppy from Vivek, preventing a crash.

- A few block core fixes from Tejun. One killing the over-optimized ioc
  exit path, cleaning that up nicely. Two others fixing an oops on
  elevator switch, due to calling into the scheduler merge check code
  without holding the queue lock.

Please pull!
