Subject: [PATCH] ACPI: processor: Drop duplicate setting of shared_cpu_map
Date: Tue, 24 Nov 2020 08:59:51 +0900 [thread overview]
Message-ID: <20201123235951.96243-1-punitagrawal@gmail.com> (raw)
'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.
