Hi Linus,

Normally I'd defer my initial for-linus pull request until after the
merge window, but a race was uncovered in the virtio-blk conversion to
blk-mq that could cause hangs. So here's a small collection of fixes for
you to pull:

- The fix for the virtio-blk IO hang reported by Dave Chinner, from
Shaohua and myself.

- Add the Insert blktrace event for blk-mq. This makes 'btt' happy when
it is doing it's state transition analysis.

- Ensure that blk-mq has disk/partition stats enabled by default,
instead of making it opt-in.

- A fix for __bio_add_page() and large sector counts.

Please pull!
