Add a driver for the on-die digital thermal sensor found on Intel Core

2007-08-15T19:26:03Z

and newer CPUs (including Core 2 and Core / Core 2 based Xeons). The driver attaches to each cpu device and creates a sysctl node in that device's sysctl context (dev.cpu.N.temperature). When invoked, the handler binds to the appropriate CPU to ensure a correct reading. Submitted by: Rui Paulo Sponsored by: Google Summer of Code 2007 Tested by: des, marcus, Constantine A.
