Sebastian Andrzej Siewior 39f152ffbf x86/mcheck: Reorganize the hotplug callbacks ... Initially I wanted to remove mcheck_cpu_init() from identify_cpu() and let it become an independent early hotplug callback. The main problem here was that the init on the boot CPU may happen too late (device_initcall_sync(mcheck_init_device)) and nobody wanted to risk receiving and MCE event at boot time leading to a shutdown (if the MCE feature is not yet enabled). Here is attempt two: the timming stays as-is but the ordering of the functions is changed: - mcheck_cpu_init() (which is run from identify_cpu()) will setup the timer struct but won't fire the timer. This is moved to CPU_ONLINE since its cleanup part is in CPU_DOWN_PREPARE. So if it is okay to stop the timer early in the shutdown phase, it should be okay to start it late in the bring up phase. - CPU_DOWN_PREPARE disables the MCE feature flags for !INTEL CPUs in mce_disable_cpu(). If a failure occures it would be re-enabled on all vendor CPUs (including Intel where it was not disabled during shutdown). To keep this working I am moving it to CPU_ONLINE. smp_call_function_single() is dropped beause the notifier runs nowdays on the target CPU. - CPU_ONLINE is invoking mce_device_create() + mce_threshold_create_device() but its cleanup part is in CPU_DEAD (mce_threshold_remove_device() and mce_device_remove()). In order to keep this symmetrical I am moving the clean up from CPU_DEAD to CPU_DOWN_PREPARE.
