Subject: [PATCH 1/4] sparc64: set node_possible_map in bootmem_init_numa()
Date: Thu, 2 Jul 2026 02:18:48 +0900 [thread overview]
Message-ID: <20260701171851.2447626-2-ekffu200098@gmail.com> (raw)
In-Reply-To: <20260701171851.2447626-1-ekffu200098@gmail.com>
Unlike other NUMA architectures, sparc64 never sets node_possible_map.
bootmem_init_numa() marks all nodes online and node_online_map does not
change afterwards, so set node_possible_map from node_online_map.
