Pull EDAC changes from Borislav Petkov:
 "EDAC queue for 3.17:

   - One new edac driver for Intel E3-12xx DRAM controllers.

   - Out-of-subsystem changes are making the non-atomic iomem 64-bit
     accessors' naming explicit to show both exact order of the 32-bit
     accesses and the non-atomicity of the 64-bit access.

     Usage locations are more verbose now as to what access is exactly
     being done vs having a not-very telling "readq" there, for example.

     This is needed by E3-12xx hardware where certain mmapped registers
     cannot be accessed with requests crossing a dword boundary.

     From Jason Baron.

   - Extending AMD MCE signatures to a new model 60h in family 15h, from
     Aravind Gopalakrishnan.

   - An unsigned check cleanup, from Fabian Frederick"
