I pulled this, but then I looked at the key type changes, and that
made me so scared that I unpulled it again.

In particular, that code will do

    shell rm -f $(CONFIG_MODULE_SIG_KEY)

from the Makefile if some config options have changed.

That just seems too broken for words. Maybe I misunderstand this, but
this really seems like an easy mistake might cause the kernel build to
actively start removing some random user key files that the user
pointed at previously.
