This is a tree wide replacement of the deprecated CPU hotplug functions
which are only wrappers around the actual functions.

Each patch is independent and can be picked up by the relevant maintainer.

The functions get_online_cpus() and put_online_cpus() have been
deprecated during the CPU hotplug rework. They map directly to
cpus_read_lock() and cpus_read_unlock().

Replace deprecated CPU-hotplug functions with the official version.
The behavior remains unchanged.

Ok; and I take it that then also is the plan for merging these ?

FWIW I'm fine with the drivers/platform/x86 patch going upstream
through some other tree if its easier to keep the set together ...

Hans

I have queued this one and 35/38 (rcutorture) for v5.16.  If you would
prefer to send them some other route, please let me know and:

There is no need to keep that set together since each patch is
independent. Please merge it through your tree.
