Merge tag 'edac_updates_for_v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras

Pull EDAC updates from Borislav Petkov:

 - Add a FRU (Field Replaceable Unit) memory poison manager which
   collects and manages previously encountered hw errors in order to
   save them to persistent storage across reboots. Previously recorded
   errors are "replayed" upon reboot in order to poison memory which has
   caused said errors in the past.

   The main use case is stacked, on-chip memory which cannot simply be
   replaced so poisoning faulty areas of it and thus making them
   inaccessible is the only strategy to prolong its lifetime.

 - Add an AMD address translation library glue which converts the
   reported addresses of hw errors into system physical addresses in
   order to be used by other subsystems like memory failure, for
   example. Add support for MI300 accelerators to that library.

 - igen6: Add support for Alder Lake-N SoC

 - i10nm: Add Grand Ridge support

 - The usual fixlets and cleanups
