  x86/mce: Handle Intel threshold interrupt storms (2023-12-15 14:53:42 +0100)

----------------------------------------------------------------
- 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

----------------------------------------------------------------
Borislav Petkov (AMD) (1):
      Documentation: Begin a RAS section

Muralidhara M K (2):
      EDAC/mce_amd: Remove SMCA Extended Error code descriptions
      x86/MCE/AMD: Add new MA_LLC, USR_DP, and USR_CP bank types

Nikolay Borisov (1):
      x86/mce: Remove redundant check from mce_device_create()

Tony Luck (3):
      x86/mce: Remove old CMCI storm mitigation code
      x86/mce: Add per-bank CMCI storm mitigation
      x86/mce: Handle Intel threshold interrupt storms

Yazen Ghannam (2):
      x86/mce/inject: Clear test status value
      x86/mce/amd, EDAC/mce_amd: Move long names to decoder module

Zhiquan Li (1):
      x86/mce: Mark fatal MCE's page as poison to avoid panic in the kdump kernel
