You should find a way to test that this is TRTTD for all gcc releases still supported for building a kernel (which may mean finding a 4.8 or 4.9 to test on to see if it uses relative or full paths). Removing these functions for kernels built with pre-change gcc will cause some semantic changes. Probably the *right* thing to do is to figure out what release it was changed in, and do some hacking to include/config/compiler-gcc.h. In addition, any such patches should be at least non-hostile to the ongoing effort to get a kernel tree that builds with clang rather than gcc.
