Bah, what is it with you people and trampolines. Why can't we, just like jump_label, patch the call directly? The whole call+jmp thing is silly, don't do that. It just wrecks I$ and is slower for no real reason afaict. Steve, also see: https://lkml.kernel.org/r/20181005081333.15018-1-ard.biesheu...@linaro.org
