You mean rasdaemon goes and offlines CPUs when certain thresholds are
reached? Sure. It would be much more flexible too.

You can add your version find_elem_cpu() or so. You can do this with a
set of function pointers which belong to the different type of storage

Hi Shiju,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on pm/linux-next]
[also build test ERROR on arm64/for-next/core linux/master linus/master
v5.9-rc3 next-20200828]
[If your patch is applied to the wrong git tree, kindly drop us a note.

When the CPU correctable errors reported on an ARM64 CPU core too often,
it should be isolated. Add the CPU correctable error collector to
store the CPU correctable error count.
When the correctable error count for a CPU exceed the threshold
value in a short time period, it will try to isolate
