PULL REQUEST md updates for 3.2

[NeilBrown]

Hi Linus,
 please pull following md updates for 3.2
 Most of them are just code cleanups and minor bug fixes.
 There is one fix for a RAID5 bug which could lead to data corruption
 due to reading old data from a device that is marked as faulty.  It is a
 small race as the drive is normally removed from consideration very soon
 after being marked faulty.  This patch is flagged for inclusion in -stable.
 It is commit 355840e7a7e56bb.

 This series conflicts with the patch
    block: remove support for bio remapping from ->make_request
 from  Christoph Hellwig in the block tree.
 That patch changes 'make_request' functions to return void.  I have patches
 which change the types of args to some of those functions from a typedef to
 a 'struct XXX'.
 The conflict is fairly easy to resolve ("wiggle" does it perfectly), or you
 could pull my "for-next" branch (85d7a4e56fbe09c1) instead which includes
 block-3.1 and resolves the conflict.

Thanks,
NeilBrown
