warning: __mcount_loc already exists: drivers/net/wireless/intel/iwlwifi/mvm/rx.o

I'm pretty sure this is unrelated to my patch, but it's a recurring

CC Shun for checking if there are problems with the bisect.

problem that we should get to the bottom of. Olof's autobuilder has reported the same thing for the 3.18-stable tree but not any others (for every single file in the kernel, not sure if this warning only shows up for all of them, or just one module).
