PULL REQUEST - md fixes for 2.6.31

[Neil Brown <neilb@suse.de>]

Hi Linus,
 Sorry that these are a little late, but I've had a few
 distractions...

 Anyway, please pull the 8 small updates for drivers/md in 2.6.31.
 Most are straight bug fixes (Some tagged for -stable).
 A couple ('Push down data integrity' and 'Use revalidate disk') are
 code cleanups that make the code more obviously correct.

Thanks,
NeilBrown
