Matthew Garrett 7d31f4602f kexec_load: Disable at runtime if the kernel is locked down ... The kexec_load() syscall permits the loading and execution of arbitrary code in ring 0, which is something that lock-down is meant to prevent. It makes sense to disable kexec_load() in this situation. This does not affect kexec_file_load() syscall which can check for a signature on the image to be booted.
