[Xen-devel] [PATCH] VMX: relax incoming BNDCFGS check

2016-05-30 Thread Jan Beulich
Accepting zero here even when !cpu_has_mpx makes the restore side symmetric to the save logic (which avoids saving the value if zero), i.e. makes either side independent of the logic on the other side. Signed-off-by: Jan Beulich --- a/xen/arch/x86/hvm/vmx/vmx.c +++ b/xen/arch/x86/hvm/vmx/vmx.c @
