A variant of lmb_alloc() that tries to allocate memory on a specified NUMA node 'nid' but falls back to normal lmb_alloc() if that fails. The caller provides a 'nid_range' function pointer which assists the allocator. It is given args 'start', 'end', and pointer to integer 'this_nid'. It places at 'this_nid' the NUMA node id that corresponds to 'start', and returns the end address within 'start' to 'end' at which memory assosciated with 'nid' ends. This callback allows a platform to use lmb_alloc_nid() in just about any context, even ones in which early_pfn_to_nid() might not be working yet. This function will be used by the NUMA setup code on sparc64, and also it can be used by powerpc, replacing it's hand crafted "careful_allocation()" function in arch/powerpc/mm/numa.c If x86 ever converts it's NUMA support over to using the LMB helpers, it can use this too as it has something entirely similar.
