Subject: x86/fpu: Move __save_fpu() into fpu/core.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2d75bcf31470b15205f915aae725a284bc8f2da8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

x86/fpu: Move __save_fpu() into fpu/core.c

This helper function is only used in fpu/core.c, move it there.

This slightly speeds up compilation.
