Subject: [PULL REQUEST - resend] md fixes for 2.6.32



Hi Linus,
 please pull some md fixes for 2.6.32 as described below. 

 The main issues related to:
  - The recently merged hardware offload for RAID6 calculations, which
    didn't handle the DDF style properly, and
  - The less recently added reshaping code that allows a RAID5 to be
    reshaped to have fewer devices.  Restarting such an array if it
    was shutdown during the reshape did not work.

 Also we remove a build-time dependency on perl.

Thanks,
NeilBrown
