[Xen-devel] [PATCH] x86/HVM: XSETBV intercept needs to check CPL on SVM only

VMX doesn't need a software CPL check on the XSETBV intercept, and SVM can do that check without resorting to hvm_get_segment_register(). Clean up what is left of hvm_handle_xsetbv(), namely make it return a proper error code. Signed-off-by: Jan Beulich --- a/xen/arch/x86/hvm/hvm.c +++ b/xen/ar
