[PATCH v2 00/15] Documentation fixes

Hi Jon,

As requested, this is a rebase of a previous series posted on Jan, 15.

Since then, several patches got merged via other trees or became
obsolete. There were also 2 patches before that fits better at the
ReST conversion patchset. So, I'll be sending it on another patch
series together with the remaining ReST conversions.

I also added reviews/acks received.

So, the series reduced from 29 to 15 patches.

Let's hope b4 would be able to properly handle this one.

Regards,
Mauro

Nope.  I don't know what it is about your patch series, but b4 is never
able to put them together.

I've applied the series except for #1, which already went through the -mm
tree.

Thanks,

jon
