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?
