Subject: [patch] alpha, mm: set all online nodes in N_NORMAL_MEMORY

For alpha, N_NORMAL_MEMORY represents all nodes that have present memory 
since it does not support HIGHMEM.  This patch sets the bit at the time 
the node is initialized.

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.
