Merge tag 'edac_updates_for_v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras

Pull EDAC updates from Borislav Petkov:

 - Add support for Skylake-S CPUs to ie31200_edac

 - Improve error decoding speed of the Intel drivers by avoiding the
   ACPI facilities but doing decoding in the driver itself

 - Other misc improvements to the Intel drivers

 - The usual cleanups and fixlets all over EDAC land
