From 3cdad9183aefc422d19271a09ad01f7dda1f0cde Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 10 Mar 2016 16:47:02 +0100 Subject: [PATCH] x86/xstate: undo bogus adjustment to xsave() This reverts an unintended change in commit 879b44b041 ("x86/fpu: add a per-domain field to set the width of FIP/FDP"), which I had done intermediately while fixing the build issue: After having reverted that adjustment I must have forgotten to "git add" the adjustment.
