Note. These first 14 patches are simply clean up patches to the sorttable.c
code. I would like to start testing these and add them to linux-next, as I
do not believe they are controversial. They should not have any real
functional change, but it would still be good to test them on other
architectures outside of the mcount code.

The last two patches are what handle the weak functions in mcount_loc. I'll
hold off on those till after the v6.14 merge window.
