the kexec_file_load() syscall.
This option enforces signature verification at generic level.
One needs to enable signature verification for type of kernel
image being loaded to make sure it works. For example, enable
bzImage signature verification option to be able to load and
verify signatures of bzImage. Otherwise kernel loading will fail.
In addition to that option, you need to enable signature
verification for the corresponding kernel image type being
loaded in order for this to work.
