Ingo, I see you picked this up for x86/urgent, but note that the bug
isn't actually triggerable until the stuff in tip/efi/core gets
merged. I'd suggest sticking this patch in tip/efi/core also.

It should be harmless to merge this patch before that, but the
references to separate EFI page tables don't make sense.
