That's not the workflow rule the Linux kernel is using, if Cc:-ing a 
patchset was the only condition for upstream inclusion then we'd have a 
*LOT* of crap in the Linux kernel.

Just applying those EFI changes without even as much as an Acked-by from 
the EFI maintainers is a *totally* unacceptable workflow.

Please revert/rebase and re-try this on the proper submission channels.

Meanwhile the broken code is NAK-ed by me:
