From 3e1bf47e5c81c2b895db4bea67f70c3ca8e5b984 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 27 May 2015 13:47:01 +0200 Subject: [PATCH] x86/fpu: Rename copy_fpstate_to_fpregs() to copy_kernel_to_fpregs() Bring the __copy_fpstate_to_fpregs() and copy_fpstate_to_fpregs() functions in line with the naming of other kernel-to-FPU-registers copying functions.
