Subject: [GIT PULL] x86/microcode for v6.6-rc1

Hi Linus,

please pull the first part of Thomas' microcode loader work, for 6.6.
The other part wasn't fully ready in time so it will follow on later.

Thx.

  x86/microcode: Remove remaining references to CONFIG_MICROCODE_AMD (2023-08-26 13:37:55 +0200)

----------------------------------------------------------------
- The first, cleanup part of the microcode loader reorg tglx has been
  working on. 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.
