Description

Newer GCC will re-order functions to allow the link-edit to better position them based on their expected call frequency.
Mostly, this is something we ignore and won't be a problem, but since kernel objects are relocatable objects, the sub-section of '.text' remain in the output, and may cause problems.

We should just not do it.
