[RFC PATCH 0/2] EDAC/ghes: Add EDAC device for recording the CPU error count

[Shiju Jose]

For the firmware-first error handling on ARM64 hardware platforms,
CPU cache corrected error count is not recorded.
Create an CPU EDAC device and device blocks for the CPU caches
for this purpose. The EDAC device blocks are created based on the
cache information from the cpu_cacheinfo.

User-space application could monitor the recorded corrected error
count for the predictive failure analysis.

More information in the patch headers.
