RE: [PATCH 0/4] ras-tools: hardware validation for arm64 MC-safe memory error recovery

[Luck, Tony]

Ruidong,

Thanks for sending this series. It looks like a very useful addition to test
cases for ras-tools.

Does x86 also handle all those cases?

I didn't look closely at how this series works, but I did notice it provides
code to disassemble binary code ... is that the ARM specific part of this
series? What would need to be changed to support x86 too?

Please add a patch to update the README file with step by step
instructions or examples of using this new capability.
