From: Ingo Molnar Date: Wed, 20 May 2015 09:35:02 +0000 (+0200) Subject: x86/fpu/init: Move __setup() functions to fpu/init.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7cf82d33b613780a79fda91babf7b9e6c5c82d75;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git x86/fpu/init: Move __setup() functions to fpu/init.c We had a number of FPU init related boot option handlers in arch/x86/kernel/cpu/common.c - move them over into arch/x86/kernel/fpu/init.c to have them all in a single place.
