Subject: mm: always set nodes with regular memory in N_NORMAL_MEMORY
From: David Rientjes <rientjes@xxxxxxxxxx>
N_NORMAL_MEMORY is intended to include all nodes that have present memory
in regular zones, that is, zones below ZONE_HIGHMEM. This should be done
regardless of whether CONFIG_HIGHMEM is set or not.
This fixes ia64 so that the nodes get set appropriately in the nodemask
for DISCONTIGMEM and mips if it does not enable CONFIG_HIGHMEM even for
32-bit kernels.
If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it
relies on this nodemask to setup kmem_cache_node data structures for each
cache.
