Re: crash in kmem_cache_init

Could you try this patch?

Memoryless nodes: Set N_NORMAL_MEMORY for a node if we do not support HIGHMEM

It seems that we only scan through zones to set N_NORMAL_MEMORY only if
CONFIG_HIGHMEM and CONFIG_NUMA are set. We need to set N_NORMAL_MEMORY
in the !CONFIG_HIGHMEM case.
