This is a good point. My understanding is that those orphaned docs
are there for two reasons:

1) someone created a new document as .rst but there's no index.rst file yet,
as there are lots of other documents already there not converted. That's
the case, for example, of the ones under Documentation/arm;

2) They're part of an undergoing effort of converting stuff to ReST.
One opted to keep it orphaned temporarily in order to avoid merge
conflicts.

That's said, I have myself a big (/86 patches and growing) series
with do a huge step on txt->rst conversion (it covers a significant
amount of documentation). On this series, I'm removing the orphaned
tags for several files (including, for example, those at Documentation/arm).

Yet, it is a lot easier to see if such series is not introducing
warnings regressions if we first address those.

It should be notice that discovering the orphaned files should be as
simple as:

	git grep -l ":orphan:" Documentation
