Merge tag 'x86_microcode_for_v6.6_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 microcode loading updates from Borislav Petkov:
 "The first, cleanup part of the microcode loader reorg tglx has been
  working on. The other part wasn't fully ready in time so it will
  follow on later.

  This part makes the loader core code as it is practically enabled on
  pretty much every baremetal machine so there's no need to have the
  Kconfig items.

  In addition, there are cleanups which prepare for future feature
  enablement"

-	  If you say Y here, you will be able to update the microcode on
-	  Intel and AMD processors. The Intel support is for the IA32 family,
-	  e.g. Pentium Pro, Pentium II, Pentium III, Pentium 4, Xeon etc. The
-	  AMD support is for families 0x10 and later. You will obviously need
-	  the actual microcode binary data itself which is not shipped with
-	  the Linux kernel.
-
-	  The preferred method to load microcode from a detached initrd is described
-	  in Documentation/arch/x86/microcode.rst. For that you need to enable
-	  CONFIG_BLK_DEV_INITRD in order for the loader to be able to scan the
-	  initrd for microcode blobs.
-
-	  In addition, you can build the microcode into the kernel. For that you
-	  need to add the vendor-supplied microcode to the CONFIG_EXTRA_FIRMWARE
-	  config option.
