load_certificate_list() parses certificates embedded in the kernel
image to load them onto the keyring.

Commit "2565ca7f5ec1 (certs: Move load_system_certificate_list to a common
function)" made load_certificate_list() a common function in the certs/
directory. Export load_certificate_list() outside certs/ to be used by
load_platform_certificate_list() for loading compiled in platform keys
onto the .platform keyring at boot time.

I think Nayna addressed your concerns.  Did you want to upstream this
patch set or would you prefer I did?

thanks,

Mimi
