From d7a7c573936a86474c4a5090a45a4bc6e680c117 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Mon, 9 Aug 2010 17:20:33 -0700 Subject: x86, ia64, smp: use workqueues unconditionally during do_boot_cpu() Workqueues are now initialized as part of the early_initcall(). So they are available for use during cold boot process aswell. Signed-off-by: Suresh Siddha Cc: "H.
