Eliminate tss - tss is meaningless in a paravirtualized kernel
and consumes 25% of the per-cpu area.
Add CONFIG_X86_NO_TSS to exclude all code which references tss.
Add CONFIG_X86_SYSENTER to conditionally include support for sysenter.
Change CONFIG_DOUBLEFAULT to depend on !CONFIG_X86_NO_TSS.
(sysenter and doublefault need tss).

Based on a patch by Jan Beulich <JBeulich@novell.com>
