linux-next: build warning after merge of the powerpc tree

Hi all,

After merging the powerpc tree, today's linux-next build (htmldocs)
produced this warning:

docutils.utils.SystemMessage: Documentation/powerpc/associativity.rst:1: (SEVERE/4) Title overline & underline mismatch.

============================
NUMA resource associativity
=============================

Introduced by commit

  1c6b5a7e7405 ("powerpc/pseries: Add support for FORM2 associativity")

There are other obvious problems with this document (but sphinx seems
to have hung before it reported them).

Like

and

Form 1

and

Form 2
