Well, from the commit comments, it looks like Paul has made some attempt
to make it bisectable (see e.g. commit de47725421ad ("include: replace
linux/module.h with "struct module" wherever possible") near the end).
And the actual split (even though it is right at the start) is not really
a problem becuase the new export.h is included in module.h anyway. The
problems come when you remove module.h from a file or replace it with

One the other hand, there are some commits near the end that are cleanrly
just fixing up problems caused by earlier commits. They could probably
be included earlier in the series (most of them are trivial).

Anyway, Paul can speak for himself.
