This precludes enabling the option in kernels using M386, M486, or M586, despite the fact that the detection code doesn't need these features and if Xen is present the features are implicitly there. At least the X86_TSC dependency can thus be dropped in my opinion, which would then only exclude M386 kernels. (Dropping X86_CMPXCHG may yield build problems, but could perhaps also be eliminated by forcibly #define-ing it in the relevant source files.)
