From e3f91083facb792dc8d8fd0a59639e4d6e7c0c8f Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Sat, 23 Jul 2016 14:42:37 +0530 Subject: [PATCH] jump_label: Make it possible for arches to invoke jump_label_init() earlier Some arches (powerpc at least) would like to invoke jump_label_init() much earlier in boot. So check static_key_initialized in order to make sure this function runs only once.
