Subject: page-allocator-use-a-pre-calculated-value-instead-of-num_online_nodes-in-fast-paths: do not override definition of node_set_online() with macro
From: David Rientjes <rientjes@xxxxxxxxxx>
Do not override definition of node_set_online() with macro
node_set_online() updates node_states[] and updates the value of
nr_online_nodes. However, its definition is being accidentally
overridden by a macro definition intended for use in the !CONFIG_NUMA
case. This patch fixes the problem by moving the !CONFIG_NUMA macro
definition.
