-Subject: [PATCH] Add secureboot pre-signing to the kernel
-
-If it detects a secure boot certificate at `keys/MOK.key` and `keys/MOK.cer`,
-the kernel Makefile will automatically sign the vmlinux / bzImage file that
-gets generated, and that is then used in packaging.
-
-By integrating it into the kernel build system directly, it is fully integrated
-with targets like `make deb-pkg` (opposed to `make all`, sign, `make bindeb-pkg`)
-and it gets added to every tree by the same mechanism that is used to apply the
-other surface patches anyways.
