My complaint was with placing the EFI table dump in the kernel table
dump, as the EFI page tables are distinct, and that VA range is shared
by other tables we map from time-to-time, e.g. the idmap.

So I would like to see the EFI tables exposed by a separate file.

I had patches [1] which librify the existing code and do just that, but
I haven't had the time to rebase and rework those. If you have the time,
feel free to pick that up!

Thanks,
Mark.
