Subject: [PATCH 0/3] EDAC: Improve memory address decoding for i10nm driver

Calling firmware to translate memory addresses has a high impact
on system because the call uses SMI.

The 10nm server processors (Icelake and Tremont) provide additional
information in the IA32_MCi_MISC registers that can be used to decode
the address of an error in DDR memory.

Couple of prep patches before the main event in part 3 that decodes
the address from the MISC register.

Qiuxu Zhuo (2):
  EDAC/skx_common: Use driver decoder first
  EDAC/skx_common: Make output format similar

Youquan Song (1):
  EDAC/i10nm: Add driver decoder for Ice Lake and Tremont CPUs
