From ac99b862fb98a36929831791da31714f709c2aa8 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 6 Jul 2011 14:20:14 +0200 Subject: jump_label: Provide jump_label_key initializers Provide two initializers for jump_label_key that initialize it enabled or disabled. Also modify all jump_label code to allow for jump_labels to be initialized enabled.
