This means that some of the COMDAT sections did not match exactly when 
the linker tried to unify them.

Basically, both the files have a copy of what is supposedly the exact 
same code. The linker then chooses one, it doesn't matter which, and 
discards the others. However, the linker first does a few sanity checks 
to make sure they are the same, and in this case it has found that they 
are not.

This can be caused in one of two ways:

1. The sections were compiled from different source code (with the same 
name). This is a user mistake and results in undefined behaviour.

2. The same source was compiled with different optimization and/or other 
compiler parameters. This is typically harmless.

The problem might be a latent bug in the kernel build system, or it 
might be a toolchain bug. I don't know yet.

Either way, my kernel built with many of those warnings, but it seems to 
run fine.
