Note that the above complaints about missing > alignment is for kernel (!) ftrace/livepatching on arm64 (!), not on x86_64. I had impression that x86-64 also needs forced alignment so the patching can be always done atomically. But it is not a big practical difference if we go with a flag specifying minimal function alignment.
