Yeah, but not in total. I didn't see any of these in the allyes
kernel I built with our proof of concept hack to avoid ld -r. I think
you'll find that these are all from ld -r output, as I assume no one
in kernel land writes drivers or whatever with 33M of text in a single
file. Branches in that monstrous section can't even reach the
trampolines that ld inserts to extend branch reach. Did I mention
that ld -r is a bad idea?
One workaround might be to compile with -ffunction-sections.
