Do you intend for this to supplement Jeff Hansen's tsc=stable patch, or to
replace it? If you intend to supplement it, you should rework your submission
to make sure that both your autodetection and his command-line option use the
same internal mechanism, and if you intend to replace it, you should say this
explicitly, and justify it. Either way, you should definitely CC Jeff on the
submission, as I am doing now.
