If anyone has any objections, please let me know. =============== commit acead1b0fac5b10d0ae3f1cc5f7820b9f9f924f5 upstream. Add CPU ID for Atom N2600/N2800 processors. Datasheets indicate support for this, detailed information about potential quirks or limitations are missing, though. So we just reuse the definition for the previous ATOM series. Tests on N2800 systems showed that this addition is fine an can reduce power consumption by about 0.25 W (personally confirmed on Intel DN2800MT).
