Revision 54577e5018a8c0cb79c9a0fa118a55c68715d398 authored by Paolo Bonzini on 20 August 2019, 15:35:52 UTC, committed by Paolo Bonzini on 21 August 2019, 08:27:35 UTC
state_test and smm_test are failing on older processors that do not
have xcr0.  This is because on those processor KVM does provide
support for KVM_GET/SET_XSAVE (to avoid having to rely on the older
KVM_GET/SET_FPU) but not for KVM_GET/SET_XCRS.
