Hi Ruidong,

Thanks for the follow up.

This patch is made redundant by the following patch in review.
https://lore.kernel.org/linux-edac/20240404151359.47970-11-yazen.ghannam@amd.com/

Also, this is still not sufficient. The address translation still needs
to be invoked in order for memory_failure() to have a valid system
physical address.

Please see the following work-in-progress patch.
https://github.com/AMDESE/linux/commit/6ddd8e90d08edb4a2730ccd02981baef4645bb43

Thanks,
Yazen
