Revision e3811a3f74bd1ad773667b78323f396166891f3a authored by Rudolf Marek on 28 November 2017, 21:01:06 UTC, committed by Ingo Molnar on 06 December 2017, 11:27:13 UTC
The latest AMD AMD64 Architecture Programmer's Manual
adds a CPUID feature XSaveErPtr (CPUID_Fn80000008_EBX[2]).

If this feature is set, the FXSAVE, XSAVE, FXSAVEOPT, XSAVEC, XSAVES
/ FXRSTOR, XRSTOR, XRSTORS always save/restore error pointers,
thus making the X86_BUG_FXSAVE_LEAK workaround obsolete on such CPUs.
