[PULL REQUEST] md: various bug fixes

[Neil Brown]

Hi Linus,
  Please consider pulling the following changes for 2.6.35.
  They are:

   - fixes for regressions introduced in -rc1 (Restore partition....)
   - fixes for enhancements added in -rc1 which were not yet perfect
        (mostly relating to 'takeover' of one level by another)
   - fixes for bugs of longer standing.
     One of these was poor handling of multiple device failure when converting
      a RAID5 to a RAID6 with several more devices.  This bug exposed 
      several issues and covers the "md/raid5:*" patches.

Thanks,
NeilBrown
