Subject: [PATCH v06 9/9] hotplug/pmt: Update topology after PMT
Date: Mon, 9 Jul 2018 09:59:04 -0500	[thread overview]
Message-ID: <d5b2e902-e34d-3eaf-2364-f6902d175f46@linux.vnet.ibm.com> (raw)
In-Reply-To: <4e6b3582-0033-b232-3769-226ba6f68eac@linux.vnet.ibm.com>

hotplug/pmt: Call rebuild_sched_domains after applying changes
to update CPU associativity i.e. 'readd' CPUs.  This is to
ensure that the deferred calls to arch_update_cpu_topology are
now reflected in the system data structures.
