It would be helpful for review if the split and restyle were distinct
patches.  Otherwise I can't tell what has changed.

This does lose the ability to use git blame to get more context on
some of the oddities in modpost (which I have found useful in the
past).  I don't feel strongly though.

^ this should go in modpost.h if it is to be used in two translation
units, rather than forward declaring it in section-check.c.  You did
this for the functions.
