    kexec_file: split KEXEC_VERIFY_SIG into KEXEC_SIG and KEXEC_SIG_FORCE
    
    This is a preparatory patch for kexec_file_load() lockdown.  A locked down
    kernel needs to prevent unsigned kernel images to be loaded with
s/to be loaded/from being loaded/
(my own mistake :-))

Otherwise looks good. Thanks for improving my idea.
