Merge tag 'ras_core_for_v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 RAS updates from Borislav Petkov:

 - Convert the hw error storm handling into a finer-grained, per-bank
   solution which allows for more timely detection and reporting of
   errors

 - Start a documentation section which will hold down relevant RAS
   features description and how they should be used

 - Add new AMD error bank types

 - Slim down and remove error type descriptions from the kernel side of
   error decoding to rasdaemon which can be used from now on to decode
   hw errors on AMD

 - Mark pages containing uncorrectable errors as poison so that kdump
   can avoid them and thus not cause another panic

 - The usual cleanups and fixlets

* tag 'ras_core_for_v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
