From 3a54450b5ed1671a6adecf501a0b4d4c1d27235d Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 24 Apr 2015 10:14:36 +0200 Subject: x86/fpu: Rename 'xsave_hdr' to 'header' Code like: fpu->state->xsave.xsave_hdr.xstate_bv |= XSTATE_FP; is an eyesore, because not only is the words 'xsave' and 'state' are repeated twice times (!), but also because of the 'hdr' and 'bv' abbreviations that are pretty meaningless at a first glance. Start cleaning this up by renaming 'xsave_hdr' to 'header'. Reviewed-by: Borislav Petkov Cc: Andy Lutomirski Cc: Dave Hansen Cc: Fenghua Yu Cc: H.
