Qiuxu Zhuo 2223d8c781 EDAC/igen6: Add debugfs interface for Intel client SoC EDAC driver 
Add debugfs support to fake memory correctable errors to test the
error reporting path and the error address decoding logic in the
igen6_edac driver.

Please note that the fake errors are also reported to EDAC core and
then the CE counter in EDAC sysfs is also increased.

Qiuxu Zhuo 10590a9d4f EDAC/igen6: Add EDAC driver for Intel client SoCs using IBECC 
This driver supports Intel client SoC with integrated memory controller
using In-Band ECC(IBECC). The memory correctable and uncorrectable errors
are reported via NMIs. The driver handles the NMIs and decodes the memory
error address to platform specific address. The first IBECC-supported SoC
is Elkhart Lake.

[Tony: s/#include <linux/nmi.h>/#include <asm/nmi.h>/ to fix randconfig build]
