Subject: [GIT PULL] x86/microcode for v6.2

Hi Linus,

please pull a pile of x86/microcode fixes for 6.2.

The IFS stuff goes through tip because the IFS driver uses the same
structures and similar functionality as the microcode loader and it made
sense to route it all through this branch so that there are no conflicts.

Thx.

  x86/microcode/intel: Do not retry microcode reloading on the APs (2022-12-05 21:22:21 +0100)

----------------------------------------------------------------
- Add support for multiple testing sequences to the Intel In-Field Scan
driver in order to be able to run multiple different test patterns.
Rework things and remove the BROKEN dependency so that the driver can be
enabled (Jithu Joseph)

- Remove the subsys interface usage in the microcode loader because it
is not really needed

- A couple of smaller fixes and cleanups
