Starting with GCC 8, a lot of unlikely code was moved out of line to "cold" subfunctions in .text.unlikely. For example, the unlikely bits of: irq_do_set_affinity() are moved out to the following subfunction: irq_do_set_affinity.cold.49() Starting with GCC 9, the numbered suffix has been removed. So in the above example, the cold subfunction is instead: irq_do_set_affinity.cold() Tweak the objtool subfunction detection logic so that it detects both GCC 8 and GCC 9 naming schemes.
