I'd expect this to either make no change or to make text larger and
data smaller.
In fact,
text data bss dec hex filename
7631 811 3016 11458 2cc2 kernel/profile.o-before
7520 779 3016 11315 2c33 kernel/profile.o-after
Both text and data got smaller and the total reduction was a whopping
143 bytes. Weirdness.
