  Merge remote-tracking branches 'ras/edac-drivers' and 'ras/edac-misc' into edac-updates (2026-10-18 12:01:02 -0700)

----------------------------------------------------------------
- Orphan several EDAC drivers: i82975x, x38, xgene, i3200. Those have been
  receiving just drive-by updates and no one really uses them. At least there
  are no traces of usage on the mailing lists. So, with the advent of
  AI-generated fixes frenzy, and because no one can really test fixes on
  those, it is time to sunset them and point them towards the eternal happy
  hunting-grounds

- Add a dummy EDAC driver with which the EDAC core glue can be exercised in
  a VM for the cases where one does not necessarily have access to the
  hardware. This glue should be extended with all the necessary functionality
  that needs and can be tested this way

- Add an EDAC driver to reset bitfix filters in Intel hardware. Bitfix
  filters are a hw mechanism for tracking stuck bits in memory and CPU arrays
  due to, e.g., silicon aging. Those filters can become clogged by transient
  errors accumulating over a long system uptime so this intel-bff (LOL :))
  driver glue resets those filters on overflow. Work by Qiuxu Zhuo and Tony
  Luck

- Export get_cpu_cacheinfo_id() for use by the new intel-bff driver

- i10nm: Handle the case where hw disables memory controllers which leads to
  reporting the wrong memory controller when reporting an error

- The now-usual AI-powered fixes and other misc cleanups and updates all over
  the place
