Dave Hansen 408fde81c1 [PATCH] remove non-DISCONTIG use of pgdat->node_mem_map ... This patch effectively eliminates direct use of pgdat->node_mem_map outside of the DISCONTIG code. On a flat memory system, these fields aren't currently used, neither are they on a sparsemem system. There was also a node_mem_map(nid) macro on many architectures. Its use along with the use of ->node_mem_map itself was not consistent. It has been removed in favor of two new, more explicit, arch-independent macros: pgdat_page_nr(pgdat, pagenr) nid_page_nr(nid, pagenr) I called them "pgdat" and "nid" because we overload the term "node" to mean "NUMA node", "DISCONTIG node" or "pg_data_t" in very confusing ways. I believe the newer names are much clearer. These macros can be overridden in the sparsemem case with a theoretically slower operation using node_start_pfn and pfn_to_page(), instead. We could make this the only behavior if people want, but I don't want to change too much at once. One thing at a time. This patch removes more code than it adds. Compile tested on alpha, alpha discontig, arm, arm-discontig, i386, i386 generic, NUMAQ, Summit, ppc64, ppc64 discontig, and x86_64.
