Hi,

Sorry for misunderstanding of this topic on my reply at [1].

After applying this patch and doing htmldocs build, I see the HTML
diff below.

So basically this doesn't promotes HWCAP2_* as headings, but rather changes
HTML element used by them from <div> & <p> to <dl> & <dd>. Otherwise I don't
see any visual differences.

Regarding the patch subject, I don't know what unifying the vertical spacing
is, so I can't tell whether the patch is correct on this context or not.

Also, when submitting next iterations of your patch series, don't forget
to pass -v <number> to git-format-patch(1) so that the patch subject
prefix contains the correct version numbers. I gave that advice because
I don't see that this patch is sent as v2 of [2].
