their signatures checked without causing a dependency loop.

-Beyond the public key generated specifically for module signing, any file
-placed in the kernel source root directory or the kernel build root directory
-whose name is suffixed with ".x509" will be assumed to be an X.509 public key
-and will be added to the keyring.
+Beyond the public key generated specifically for module signing, additional
+trusted certificates can be provided in a PEM-encoded file referenced by the
+CONFIG_SYSTEM_TRUSTED_KEYS configuration option.
Further, the architecture code may take public keys from a hardware store and
add those in also (e.g. from the UEFI key database).
