I've reproduced this failure and it is basically the same as the one seen 
in linux-next (which also involved CONFIG_EFI_STUB). The same changes 
which resolved that for x86 also resolved this new error:

Peter, this patch has your name on it, so I wonder if you have any 
comment. Would you prefer that I submit my version under my name instead 
of yours?
