| |
'shared_cpu_map', stored as part of the per-processor acpi_processor_performance structre, is used to store cpus that share a performance domain. 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.
