We're talking about these three patches, yes?

https://lkml.org/lkml/2015/2/20/546
https://lkml.org/lkml/2015/5/4/614
https://lkml.org/lkml/2015/5/7/488

I think the third is obsolete now that we allow the user to provide
their own certificate + key by setting CONFIG_MODULE_SIG_KEY, because
the in-tree signing_key.{priv,x509} are *always* autogenerated.

The first two I don't think go far enough. I dislike automatically
picking up files that were lying around in the tree, and it's still
going to break if there's a file with a space in its name.

Let's just introduce a new Kconfig option for 'extra certificates' which
takes the filename of a PEM-format file. We can process that into DER
form with some fairly trivial modifications to scripts/extract-cert.c.
