Hi all,

this series is the scond part of cleaning up lifetimes and allocation of
the gendisk and request_queue structure. It adds a new interface to
allocate the disk and queue together for blk based drivers, and uses that
in all drivers that do not have any caveats in their gendisk and
request_queue lifetime rules.
