Pull block fixes from Jens Axboe:
"Final round of fixes for this merge window - some of this has come up
after the initial pull request, and some of it was put in a post-merge
branch before the merge window.
This contains:
- Fix for a bad check for an error on dma mapping in the mtip32xx
driver, from Alexey Khoroshilov.
- A set of fixes for lightnvm, from Javier, Matias, and Wenwei.
- An NVMe completion record corruption fix from Marta, ensuring that
we read things in the right order.
- Two writeback fixes from Tejun, marked for stable@ as well.
- A blk-mq sw queue iterator fix from Thomas, fixing an oops for
sparse CPU maps. They hit this in the hot plug/unplug rework"
