Thanks for this. That patch just moves a small amount of code, so it's likely
that it's caused something to get placed out of range of its caller, or the
linker started generating a stub for some reason. I can't immediately see the
problem, but it could be specific to your exact toolchain.

Something that might help, would you be able to put the compiled vmlinux binaries
from before/after the bad patch somewhere I can grab them?
