Guys, this is not a dick-sucking contest.

If you want to parse PE binaries, go right ahead.

If Red Hat wants to deep-throat Microsoft, that's *your* issue.  That
has nothing what-so-ever to do with the kernel I maintain. It's
trivial for you guys to have a signing machine that parses the PE
binary, verifies the signatures, and signs the resulting keys with
your own key. You already wrote the code, for chissake, it's in that
f*cking pull request.

Why should *I* care? Why should the kernel care about some idiotic "we
only sign PE binaries" stupidity? We support X.509, which is the
standard for signing.

Do this in user land on a trusted machine. There is zero excuse for
doing it in the kernel.
