Subject: x86/fpu/init: Move __setup() functions to fpu/init.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7cf82d33b613780a79fda91babf7b9e6c5c82d75;p=openwrt%2Fstaging%2Fblogic.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.
