Confused.

Why have you rewritten the patch that I sent Satuday morning?

  https://lkml.org/lkml/2014/3/22/61

I don't think your version goes far enough because you've left all the
efi_early->call() stuff in eboot.c. So now there's two ways to invoke
EFI functions in the x86 boot stub.

What's wrong with the patch that I sent?
