Yes, I will implement it! We are still working on loading the public
keys for kernel signing from the firmware into a kernel keyring, so
there's not much point in implementing arch_kexec_kernel_verify_sig
without having that first.
The same problem also affects IMA: even with these patches, new code
still neededs to be added to make IMA use the platform keys for kernel
signature verification.
