got rid of EFI depending on real_mode_header->trampoline_pgd
So I think it only got rid of by default - the codepath is still there, the allocation is still there, it's just that it's not actually used unless somebody does that "efi=old_mmap" thing.
Yes, the trampoline_pgd is still around, but I can't figure out how it would be used after boot. Confused, digging more.
Thanks,
