Subject: [PATCH v3 03/11] powerpc/smp: Remove get_physical_package_id
Date: Thu, 8 Oct 2020 00:07:52 +0530 [thread overview]
Message-ID: <20201007183800.27415-4-srikar@linux.vnet.ibm.com> (raw)
In-Reply-To: <20201007183800.27415-1-srikar@linux.vnet.ibm.com>
Now that cpu_core_mask has been removed and topology_core_cpumask has
been updated to use cpu_cpu_mask, we no more need
get_physical_package_id.
