mm/slab: Fix undefined init_cache_node_node() for NUMA and !SMP
commit 66a1c22b709178e7b823d44465d0c2e5ed7492fb upstream.
sh/migor_defconfig:
mm/slab.c: In function ‘slab_memory_callback’:
mm/slab.c:1127:23: error: implicit declaration of function ‘init_cache_node_node’; did you mean ‘drain_cache_node_node’? [-Werror=implicit-function-declaration]
1127 | ret = init_cache_node_node(nid);
| ^~~~~~~~~~~~~~~~~~~~
| drain_cache_node_node
The #ifdef condition protecting the definition of init_cache_node_node()
no longer matches the conditions protecting the (multiple) users.
Fix this by syncing the conditions.
Fixes: 76af6a054da40553 ("mm/migrate: add CPU hotplug to demotion #ifdef")
