Ashok Raj 3ecf671f1d x86/microcode: Document the whole late loading problem 
Commit

  d23d33ea0fcd ("x86/microcode: Taint and warn on late loading")

started tainting the kernel after microcode late loading.

There is some history behind why x86 microcode started doing the late
loading stop_machine() rendezvous. Document the whole situation.

No functional changes.
