One commit in there looks rather dirty:

|     Aha.  You are now calling machvec_init_from_cmdline() too early (before
|     efi_init() and io_port_init()) ... so we croak accessing things

|     command line parsing before calling setup_arch().

taking some terminal exercise by jumping off the cliff like lemmings.
