  preempt: Restore preemption model selection configs (2021-11-11 13:09:33 +0100)

----------------------------------------------------------------
- Avoid touching ~100 config files in order to be able to select
the preemption model

- clear cluster CPU masks too, on the CPU unplug path

- prevent use-after-free in cfs

- Prevent a race condition when updating CPU cache domains

- Factor out common shared part of smp_prepare_cpus() into a common
helper which can be called by both baremetal and Xen, in order to fix a
booting of Xen PV guests
