Subject: linux-next: md tree build failure

Hi Neil,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

drivers/md/raid0.c: In function 'create_strip_zones':
drivers/md/raid0.c:243: error: 'struct request_queue' has no member named 'hardsect_size'

Caused by commit e1defc4ff0cf57aca6c5e3ff99fa503f5943c1f1 ("block: Do
away with the notion of hardsect_size") from the block tree interacting
with commit 131e4477401ae76a9cbe8539e4b7819e04cfba36 ("md: raid0: chunk
size check in raid0_run") from the md tree.

I applied the following patch.
