[PATCH v5 0/2] x86/intel: Update the old microcode list with a script

From: Sohil Mehta

Date: Mon Apr 06 2026 - 21:44:53 EST


It has been approximately 6 months since the old microcode list was
updated. Now bump up the current minimum microcode revisions (May 2025)
by 6 months using the November 2025 public release.

This series is based on tip x86/microcode branch which has Dave's
patches to take the platform ID into account for old microcode checks.

Changes in v5
-------------
- Refresh the old microcode list with the November 2025 public release.
- Update the script with Andy Cooper's suggestions as well as some other
improvements.

v4: https://lore.kernel.org/all/20260130194753.672739-1-sohil.mehta@xxxxxxxxx/
