Note that it's not that I think the FMODE_READ check is necessarily
_needed_. It's more the discrepancy between the commit message and the
code change that I don't like.

The commit message implies that __kernel_read() has _more_ checks than
the checks done by integrity_kernel_read(). But it looks like they
aren't so much "more" as they are just "different".
