Subject: x86/fpu: Remove the extra fpu__detect() layer
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c66e3f28237199629358e9e5a76973c400a54041;p=deliverable%2Flinux.git

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.
