  md/raid10: fix the 'new' raid10 layout to work correctly. (2015-10-24 16:24:25 +1100)

----------------------------------------------------------------
Some raid1/raid10 fixes.

Two fixes for bugs that are in both raid1 and raid10.
Both related to bad-block-lists and at least one needs
to be back ported to 3.1.

Also a revision for the "new" layout in raid10.
This "new" code (which aims to improve robustness) actually
reduces robustness in some cases.
It probably isn't in use at all as not public user-space code
makes use of these new layouts.
However just in case someone has their own code, it would be
good to get the WARNing out for them sooner.
