[RFC Patch V1 18/30] mm, bnx2fc: Use cpu_to_mem()/numa_mem_id() to support memoryless node

[Jiang Liu]

When CONFIG_HAVE_MEMORYLESS_NODES is enabled, cpu_to_node()/numa_node_id()
may return a node without memory, and later cause system failure/panic
when calling kmalloc_node() and friends with returned node id.
So use cpu_to_mem()/numa_mem_id() instead to get the nearest node with
memory for the/current cpu.

If CONFIG_HAVE_MEMORYLESS_NODES is disabled, cpu_to_mem()/numa_mem_id()
is the same as cpu_to_node()/numa_node_id().
