The "but working" is not because it would be right, but because it booted a real 64-bit distribution successfully, and I actually used that kernel.

But that only tests the native 64-bit case, it in no way tests the compat or x32 cases what-so-ever. That part was literally a "it compiles - it must be perfect" with absolutely zero testing of even the most trivial kind.

And it really would have been most trivial to just do a "Hello world" and build it with "-m32".
