Are you sure? I thought the fix was to build 2 page tables for 0-8M
instead of 1 page table for 0-4M. So, we still cannot boot a bzImage more
than 2.5M which roughly corresponds to 8M. Is this incorrect? Are you
saying I should be able to boot a bzImage corresponding to an ELF object
vmlinux of 4G or more?

I tried it and it failed (a few weeks ago) so at least reasonably recently
what you are saying was not true. I will now check if it suddenly became
true now.
