Subject: [PATCH 2/3] Revert "powerpc/topology: Update topology_core_cpumask"
Date: Thu, 15 Apr 2021 17:39:33 +0530	[thread overview]
Message-ID: <20210415120934.232271-3-srikar@linux.vnet.ibm.com> (raw)
In-Reply-To: <20210415120934.232271-1-srikar@linux.vnet.ibm.com>

Now that cpu_core_mask has been reintroduced, lets revert
commit 4bce545903fa ("powerpc/topology: Update topology_core_cpumask")

Post this commit, lscpu should reflect topologies as requested by a user
when a QEMU instance is launched with NUMA spanning multiple sockets.
