... trying to set a replying to myself record
I sent the wrong patch, but here's the important part:
-void __init node_alloc_mem_map(struct pglist_data *pgdat)
+static void __init alloc_node_mem_map(struct pglist_data *pgdat)
{
unsigned long size;
- size = (pgdat->node_spanned_pages + 1) * sizeof(struct page);
- pgdat->node_mem_map = alloc_bootmem_node(pgdat, size);
+ /* Skip empty nodes */
+ if (!pgdat->node_spanned_pages)
+ return;
+
+ /* ia64 gets its own node_mem_map, before this, without bootmem */
+ if (!pgdat->node_mem_map) {
+ size = (pgdat->node_spanned_pages + 1) * sizeof(struct page);
+ pgdat->node_mem_map = alloc_bootmem_node(pgdat, size);
+ }
#ifndef CONFIG_DISCONTIGMEM
- mem_map = contig_page_data.node_mem_map;
+ /*
+ * With no DISCONTIG, the global mem_map is just set as node 0's
+ */
+ if (pgdat == NODE_DATA(0))
+ mem_map = NODE_DATA(0)->node_mem_map;
#endif
}
