[PATCH 07/27] kexec_file: Disable at runtime if securelevel has been set

Huh?! ?With the "secure_boot" policy enabled on the boot command line,
IMA-appraisal would verify the kexec kernel image, firmware, kernel
modules, and custom IMA policy signatures.

What happens if the "secure_boot" policy isn't enabled on the boot command
line?  Can you sum up both cases in a paragraph I can add to the patch
description?

Other patches in this patch series need to be updated as well to check
if IMA-appraisal is enabled.

Which exactly?  I've added your "!is_ima_appraise_enabled() &&" line to
kexec_file() and module_sig_check().  Anything else?
