Merge tag 'ras_core_for_v5.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull RAS updates from Borislav Petkov:
 "A relatively big amount of movements in RAS-land this time around:

   - First part of a series to move the AMD address translation code
     from arch/x86/ to amd64_edac as that is its only user anyway

   - Some MCE error injection improvements to the AMD side

   - Reorganization of the #MC handler code and the facilities it calls
     to make it noinstr-safe

   - Add support for new AMD MCA bank types and non-uniform banks layout

   - The usual set of cleanups and fixes"
