From 1a7dc0db7181ebc8b9ec17e5a15ad4c766c7d3d4 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 3 Apr 2015 11:33:52 +0200 Subject: [PATCH] x86/fpu: Rename fpu_detect() to fpu__detect() Use the fpu__*() namespace to organize FPU ops better. Also document fpu__detect() a bit. Reviewed-by: Borislav Petkov Cc: Andy Lutomirski Cc: Dave Hansen Cc: Fenghua Yu Cc: H.
