IMO just return in case if (efi_setup) is true make sense.
Yes, I think it makes sense to skip touching the BGRT on kexec boot.
As a side note, we

Right. The kernel copies this image precisely because it
Hi,
As you pointed out above, a wild pointer could cause a
WARN from early_ioremap. We need to never follow the pointer in the
first place after a kexec, unless we have some way to know that it's
actually valid.
