78d88e8a3d edac: rename edac_core.h to edac_mc.h
Now, all left at edac_core.h are at drivers/edac/edac_mc.c,
so rename it to edac_mc.h.

953dee9bbd EDAC, ie31200_edac: Add Skylake support
Skylake adjusts some register locations, but otherwise follows the
existing model quite closely. I was able to verify that the 'ce_count'
increments when 'bad dimms' are used. The accounting of 'ce_count' and
'ue_count' is the primary functionality of interest for us. Tested on
Intel(R) Xeon(R) CPU E3-1260L v5 @ 2.90GHz.

2f8e2c8777 move io-64-nonatomic*.h out of asm-generic
These are not implementations of default architecture code but helpers
for drivers. Move them to the place they belong to.

78fd4d1242 ie31200_edac: Allocate mci and map mchbar first
Check for memory allocation and mchbar mapping failures before
initializing the dimm info tables needlessly.

7ee40b897d ie31200_edac: Introduce the driver
Add a driver for the E3-1200 series of Intel DRAM controllers, based on
the following E3-1200 specs:

http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200-family-vol-2-datasheet.html
http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200v3-vol-2-datasheet.html

I've tested this on bad memory hardware, and observed correlating bad
reads and uncorrected memory errors as reported by the driver.

Tested against:

CPU E3-1270 v3 @ 3.50GHz : 8086:0c08 (haswell)
CPU E3-1270 V2 @ 3.50GHz : 8086:0158 (ivy bridge)
CPU E31270 @ 3.40GHz : 8086:0108 (sandy bridge)
