KVM: VMX: Fix conditions for guest IA32_XSS support
Volume 4 of the SDM says that IA32_XSS is supported if CPUID(EAX=0DH,ECX=1):EAX.XSS[bit 3] is set, so only the X86_FEATURE_XSAVES check is necessary (X86_FEATURE_XSAVES is the Linux name for CPUID(EAX=0DH,ECX=1):EAX.XSS[bit 3]). Fixes: 4d763b16 ("KVM: VMX: check CPUID before allowing read/write of IA32_XSS") Reviewed-by:Jim Mattson <jmattson@google.com> Signed-off-by:
