This is a straightforward conversion. We place this callback last in the list so that the LED illuminates only after a successful bring up sequence. ( NOTE: The patch adds a FIXME question about the callback used, this question should probably be revisited later on.)

As part of the hotplug cleanup, the CPU_STARTING/DYING actions are going away soon. This driver needlessly uses those two macro, and so this patch replaces that code with something more sensible. Commit: 8da83734 ("ACPI / processor: Fix STARTING/DYING action in acpi_cpu_soft_notify()") added checks for those two actions, because the notification callback can sleep, causing a hung CPU. This patch instead checks for the ONLINE/DEAD actions, which are the ones that are handled by the driver in the first place.

Since the following commit: 1cf4f629 ("cpu/hotplug: Move online calls to hotplugged cpu") ... the CPU_ONLINE and CPU_DOWN_PREPARE notifiers are always run on the hot plugged CPU, and as of commit: 3b9d6da6 ("cpu/hotplug: Fix rollback during error-out in __cpu_disable()") the CPU_DOWN_FAILED notifier also runs on the hot plugged CPU. This patch converts the SMP functional calls into direct calls. smp_function_call_single() executes the function with interrupts disabled. This calling convention is not preserved because there is no reason to do so.

Convert the notifiers to state machine states and let the core code do the setup for the already online CPUs. This notifier has a completely undocumented ordering requirement versus perf hardcoded in the notifier priority. This odering is only required for CPU down, so that hardware migration happens before the core is notified about the outgoing CPU.

Replace the perf_notifier() install mechanism, which invokes magically the callback on the current CPU. Convert the hardware specific callbacks which are invoked from the x86 perf core to return proper error codes instead of totally pointless NOTIFY_BAD return values.

Actually a nice symmetric startup/teardown pair which fits properly into the state machine concept. In the long run we should be able to invoke the startup callback for the boot CPU via the state machine and get rid of the init function which invokes it on the boot CPU. Note: This comes actually before the perf hardware callbacks. In the notifier model the hardware callbacks have a higher priority than the core callback. But that's solely for CPU offline so that hardware migration of events happens before the core is notified about the outgoing CPU. With the symetric state array model we have the following ordering: UP: core -> hardware DOWN: hardware -> core Signed-off-by: NThomas Gleixner <tglx@linutronix.de> Signed-off-by: NAnna-Maria Gleixner <anna-maria@linutronix.de> Reviewed-by: NSebastian Siewior <bigeasy@linutronix.de> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Arnaldo Carvalho de Melo <acme@kernel.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Oleg Nesterov <oleg@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Rasmus Villemoes <linux@rasmusvillemoes.dk> Cc: rt@linutronix.de Link: http://lkml.kernel.org/r/20160713153333.587514098@linutronix.deSigned-off-by: NIngo Molnar <mingo@kernel.org>
