I cannot find any of these in my linus git tree kernel. But google
showed up Xen. So under my Xen unstable, this is what I have found:
In the linux-2.6.18-xen.hg subdirectory:

as for its purpose - the linux-2.6.18-xen.hg subdirectory implements
the dom0 kernel - which runs under the control of the Xen hypervisor
(which comes under the "xen" subdirectory). So practically anything
can be emulated. And for this specific configuration the TSS is
emulated in software - no hardware TSS is assumed. Default is Y for
Xen - usually like this:
#ifndef CONFIG_X86_NO_TSS
struct tss_struct * tss = &per_cpu(init_tss, cpu);
#endif
