Re: [tip:x86/urgent] x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernels

Run a 32-bit VM.  The 32-bit kernel does this right.

I suspect it would also work fine in a Qemu user mode guest (is this supported by KVM?), in a ReactOS VM, or some other number of combinations.

The real question is how many real users are actually affected.
