Tim, Your patch looks good, but your patch description needs some care:
Please do not write full sentences in the subject line. The subject line should be a short and precise information about the patch. The format is: [PATCH] subsystem: Short precise description. in this case: [PATCH] x86/centaur: Mark TSC invariant Then you add a decsription of the change in the body of the mail. Please avoid wording like 'This patch does ...'. We already know that this is a patch and the description should be more focussed on the WHY than on the WHAT. The WHAT can be seen from the patch itself, but the WHY is the information which is not in the code. See also Documentation/process/submitting-patches.rst Thanks, tglx
