Same here: so maybe make might_fault a wrapper
around __might_fault as well.
Yes, I also noticed that. It was part of the original code.
For now I kept this revert as close as possible to
the original patch.

Better fix this in an add-on patch? Or directly in this commit? At least for
the in-header function it is easy to fix in this patch.

Thanks!
