Joel Fernandes (Google) 352b152905 tick/nohz: Fix cpu_is_hotpluggable() by checking with nohz subsystem ... [ Upstream commit 58d7668242647e661a20efe065519abd6454287e ] For CONFIG_NO_HZ_FULL systems, the tick_do_timer_cpu cannot be offlined. However, cpu_is_hotpluggable() still returns true for those CPUs. This causes torture tests that do offlining to end up trying to offline this CPU causing test failures. Such failure happens on all architectures. Fix the repeated error messages thrown by this (even if the hotplug errors are harmless) by asking the opinion of the nohz subsystem on whether the CPU can be hotplugged. [ Apply Frederic Weisbecker feedback on refactoring tick_nohz_cpu_down(). ] For drivers/base/ portion: Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: Frederic Weisbecker <frederic@kernel.org> Cc: Frederic Weisbecker <frederic@kernel.org> Cc: "Paul E.
