[PATCH] enable booting a NUMA system where some nodes have no memory
When booting a NUMA system with nodes that have no memory (eg by limiting memory), bootmem_alloc_core tried to find pages in an uninitialized bootmem_map. This caused a null pointer access. This fix adds a check, so that NULL is returned. That will enable the caller (bootmem_alloc_nopanic) to alloc memory on other without a panic.
