x86/ldt: Disable 16-bit segments on Xen PV Xen PV doesn't implement ESPFIX64, so they don't work right. Disable them. Also print a warning the first time anyone tries to use a 16-bit segment on a Xen PV guest that would otherwise allow it to help people diagnose this change in behavior. This gets us closer to having all x86 selftests pass on Xen PV. Signed-off-by: Andy Lutomirski <luto@kernel.org>
