Long ago and far away. I wrote the 64bit entry code for a bzImage by putting an ELF header in the boot sector. That is what that comment referred to when it was written. Andrew had a problem on one of his test machines and so the patch to bootsector was dropped. Booting with a vmlinux file does (or at least should not) need this. ELF loaders will pick the entry point out from the ELF header. I don't know what has happened in the intervening time, or who if anyone has depended on that offset. The original intent an internal use hard code.
