Let's update the patch description providing a bit more background
info:

The archictecture specific policy rules, currently defined for EFI and
powerpc, require the kexec kernel image and kernel modules to be
validly signed and measured, based on the system's secure boot and/or
trusted boot mode and the IMA_ARCH_POLICY Kconfig option being enabled.

Perhaps include something about namespaces being allowed or not allowed
to kexec a new kernel or load kernel modules.

thanks,
