m68k/mm: Set all online nodes in N_NORMAL_MEMORY
commit 4aac0b4815ba592052758f4b468f253d383dc9d6 upstream.
For m68k, N_NORMAL_MEMORY represents all nodes that have present memory
since it does not support HIGHMEM. This patch sets the bit at the time
node_present_pages has been set by free_area_init_node.
At the time the node is brought online, the node state would have to be
done unconditionally since information about present memory has not yet
been recorded.
If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it
uses this nodemask to setup per-cache kmem_cache_node data structures.
This pach is an alternative to the one proposed by David Rientjes
<rientjes@google.com> attempting to set node state immediately when
bringing the node online.
