From c66e3f28237199629358e9e5a76973c400a54041 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sun, 26 Apr 2015 15:12:44 +0200 Subject: [PATCH] x86/fpu: Remove the extra fpu__detect() layer Now that fpu__detect() has become an empty layer around fpu__init_system(), eliminate it and make fpu__init_system() the main system initialization routine.
