From 6ee0578b4daaea01c96b172c6aacca43fd9807a6 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Fri, 30 Jul 2010 14:57:37 -0700 Subject: workqueue: mark init_workqueues() as early_initcall() Mark init_workqueues() as early_initcall() and thus it will be initialized before smp bringup. init_workqueues() registers for the hotcpu notifier and thus it should cope with the processors that are brought online after the workqueues are initialized. x86 smp bringup code uses workqueues and uses a workaround for the cold boot process (as the workqueues are initialized post smp_init()). Marking init_workqueues() as early_initcall() will pave the way for cleaning up this code.
