Subject: [PATCH 3/4] powerpc/numa: set node_possible_map from node_online_map
Date: Thu, 2 Jul 2026 02:18:50 +0900 [thread overview]
Message-ID: <20260701171851.2447626-4-ekffu200098@gmail.com> (raw)
In-Reply-To: <20260701171851.2447626-1-ekffu200098@gmail.com>
mem_topology_setup() intersects node_possible_map with node_online_map.
Nothing sets node_possible_map before this, so it is NODE_MASK_ALL and
the result is just node_online_map.
In preparation for changing node_possible_map's initial value,
mem_topology_setup() no longer depends on it.
No functional change.
