Hi!

This is version 3 of the reworked parallel bringup series. Version 2 can be
found here:

   https://lore.kernel.org/lkml/20230504185733.126511787@linutronix.de

This is just a quick reiteration to address the following details:

  1) Drop the two extended topology leaf patches as they are not longer
     relevant (Andrew Cooper)

  2) Make the announce_cpu() fixup work for real (Micheal Kelley)

Other than that there are no changes and the other details are all the same
as in V2.

Thanks,

	tglx
