Pull final final block IO fixes from Jens Axboe:
"Yes, the last round was final. This one is final final.
The mtip32xx fix could have waited, but it's so simple and gets rid of
two warning spewages on load. The two block flush fixes are critical
for blk-mq, and are the primary reason for this late pull request"

mtip32xx: fix bad use of smp_processor_id()
block: change flush sequence list addition back to front add
