By definition it contains the owning CPU. While building the 'shared_cpu_map' it is being set twice - once while initialising the performance domains and again when matching CPUs belonging to the same domain. Drop the unnecessary initialisation. Signed-off-by: Punit Agrawal Signed-off-by: Rafael J.
