This is likely the version which would be used for LPC2025 discussion on
this topic. Feel free to provide your suggestion and hoping for a solution
that works for different architectures and it's use cases.
All the existing alternatives such as cpu hotplug, creating isolated
partitions etc break the user affinity. Since number of CPUs to use change
depending on the steal time, it is not driven by User. Hence it would be
wrong to break the affinity. This series allows if the task is pinned
only paravirt CPUs, it will continue running there.
Changes compared v3[1]:
There is no "v" for this series :(
