This was still under discussion, Sudeep preferring an alternative in the driver:
http://lkml.kernel.org/r/20200727172744.GD8003@bogus http://lkml.kernel.org/r/20200724131059.GB6521@bogus
Sumit came with a new diff inline that fixes the driver instead of exporting the __cpu_logical_map.

Sumit, Sudeep, is the above diff sufficient and can it go upstream?
Thanks.
