From fc6d73d67436e7784758a831227bd019547a3f73 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 26 Feb 2016 18:43:40 +0000 Subject: arch/hotplug: Call into idle with a proper state Let the non boot cpus call into idle with the corresponding hotplug state, so the hotplug core can handle the further bringup. That's a first step to convert the boot side of the hotplugged cpus to do all the synchronization with the other side through the state machine. For now it'll only start the hotplug thread and kick the full bringup of the cpu. Signed-off-by: Thomas Gleixner Cc: linux-arch@vger.kernel.org Cc: Rik van Riel Cc: Rafael Wysocki Cc: "Srivatsa S.
