SYNOPSIS
     To	compile	this driver into the kernel, place the following lines into
     the kernel	configuration file:

DESCRIPTION
     The ig4 driver provides access to peripherals attached to an I2C SMB con-
     troller.  ig4 supports the	SMBus controller found in fourth generation
     Intel(R) Core(TM) processors based	on the mobile U-processor line for
     intelligent systems.  This	includes the i7-4650U, i5-4300U, i3-4010U, and
     2980U.

		     ters to console and syslog	once.  The sysctl resets to
		     zero immediately.
