		This driver permits reading of the internal temperature sensor of AMD
		Family 10h and 11h processors.

		All these processors have a sensor, but on older revisions of Family 10h
		processors, the sensor may return inconsistent values (erratum 319). The
		driver will refuse to load on these revisions unless you specify the
		"force=1" module parameter.
		All these processors have a sensor, but on those for Socket F or AM2+,
		the sensor may return inconsistent values (erratum 319). The driver
		will refuse to load on these revisions unless you specify the "force=1"
		module parameter.

		Due to technical reasons, the driver can detect only the mainboard's
		socket type, not the processor's actual capabilities. Therefore, if you
		are using an AM3 processor on an AM2+ mainboard, you can safely use the
		"force=1" parameter.

		There is one temperature measurement value, available as temp1_input in
		sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.
