From 9dfe99b755a263f9f6ac1dfdb5512bd6e22c28e8 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 29 Apr 2015 20:55:19 +0200 Subject: [PATCH] x86/fpu: Rename restore_xstate_sig() to fpu__restore_sig() restore_xstate_sig() is a misnomer: it's not limited to 'xstate' at all, it is the high level 'restore FPU state from a signal frame' function that works with all legacy FPU formats as well. Rename it (and its helper) accordingly, and also move it to the fpu__*() namespace. Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Dave Hansen Cc: Fenghua Yu Cc: H.
