Will Deacon ef5e724b25 arm64: alternative: put secondary CPUs into polling loop during patch ... When patching the kernel text with alternatives, we may end up patching parts of the stop_machine state machine (e.g. atomic_dec_and_test in ack_state) and consequently corrupt the instruction stream of any secondary CPUs. This patch passes the cpu_online_mask to stop_machine, forcing all of the CPUs into our own callback which can place the secondary cores into a dumb (but safe!) polling loop whilst the patching is carried out.
