Subject: [PATCH 14/18] powerpc/numa: remove arch_update_cpu_topology
Date: Fri, 12 Jun 2020 00:12:34 -0500 [thread overview]
Message-ID: <20200612051238.1007764-15-nathanl@linux.ibm.com> (raw)
In-Reply-To: <20200612051238.1007764-1-nathanl@linux.ibm.com>
Since arch_update_cpu_topology() doesn't do anything on powerpc now,
remove it and associated dead code.
