powercap: intel_rapl: Replace deprecated CPU-hotplug functions2021-08-04T18:13:46+00:00Sebastian Andrzej Siewiorbigeasy@linutronix.de2021-08-03T14:16:01+00:00urn:sha1:5d4c779cb62e676aedc278de910b4bb8ef65a5cc
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.

The DTPM framework will evolve in the next cycles. Let's add a
temporary EXPERIMENTAL tag to the option so users will be aware
the API may change over time.

The root node is not set to NULL when the dtpm root node is
removed. Consequently, it is not possible to create a new root
as it is already set.
Set the root node to NULL when the last node is removed.

It's not a good idea to access the phys_proc_id of cpuinfo directly.
Use topology_physical_package_id(cpu) instead.

The kzalloc allocation for dtpm_cpu is currently allocating the size
of the pointer and not the size of the structure. Fix this by using
the correct sizeof argument.
