You remain extremely unpleasant to communicate with. Can we keep things on topic please?
As far as I can tell, the early patching code on ARM does not rely on the early fixmap code. Did you try just moving jump_label_init() earlier in the function? Also, how did you test this change?
Just booting a few configs in QEMU. I don't have access to real hardware right now unfortunately. Let me give a try to just moving the jump_label_init() function alone. That'd certainly make this patch a lot more basic, which would be a good thing, and might assuage your well justified concerns that too much boot order churn will break something subtle. I was just afraid of complicated intermingling with the other stuff after I saw that arm64 did things in the other order. But maybe that's silly. I'll send a v2 if that works, and send an update here if it doesn't. Thanks for the suggestion.
