a0c8a17f66 Fix write_init_super usage when hot-adding a spare
Using write_init_super to add a spare to an active array is quite
different to how it is used when creating an array.

It mostly works, but if we are adding two devices to an array,
then when we add the second, there are still traces of the first
which confuse write_init_super.

So get write_init_super to ignore those traces.  Longer term, we
probably want to do this differently as for DDF, hot-adding to
an active array will have to be quite different - it will want to
write to all metadata, possibly via mdmon.

Yes, we do want to free the buf, and the space too if it is still
there.

d024b0a7eb Always assume_clean for raid0, linear, multipath, faulty
For arrays that don't have redundancy (raid0, linear etc), the
clean/dirty distinction doesn't mean anything.  So always
'assume clean' for these arrays.

91c0038813 Fix confusing usage in md.4 man page.
"degraded write performance" could be confused with "write performance
when degraded".  It really means "reduced write performance", so say
that.

51ac42e392 Italic/bold fixes in man pages.
Two places that should have been .B or .I were .M, which of
course is an error.
So fix these and that the opportunity to be more consistent
with highlighting of "mdadm".  Make it always italic except when
used as a literal example, then bold.

60b435db5a Fix bug in forced assemble.
From: Chris Webb <chris@arachsys.com>

We are loading into the already-loaded 'st' instead of the
newly create 'tst', which is clearly wrong.

56f8add211 Fix an error when assembling arrays that are in the middle of a reshape.
It is important that dup_super always returns an 'st' with the same
->ss and ->minor_version as the st that was passed.
This wasn't happening for 0.91 metadata (i.e. in the middle of a reshape).

4a04ec6ca1 imsm: ->getinfo_super set raid_disk to disk.number
A spare device by definition will have raid_disk set to -1, but when
assembling the container we want this disk to by included.

Fixes a SIGSEGV when doing:
mdadm -A /dev/imsm -e imsm /dev/sd[b-e]

...where /dev/sde is marked as a global spare device

3d2b16e77c Avoid NULL reference calling free_super and elsewhere.
Since we made free_super a superswitch call, we need to be careful
that st is non NULL before calling st->ss->free_super(st).
Also when updating byteorder there is a chance of a similar NULL
deref.
