From 1a27fc0a42162964d758e9d36d2d1b49c082a67c Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Tue, 18 Mar 2008 12:52:37 -0700 Subject: x86_64: fix setup_node_bootmem to support big mem excluding with memmap typical case: four sockets system, every node has 4g ram, and we are using: memmap=10g$4g to mask out memory on node1 and node2 when numa is enabled, early_node_mem is used to get node_data and node_bootmap. if it can not get memory from the same node with find_e820_area(), it will use alloc_bootmem to get buff from previous nodes. so check it and print out some info about it. need to move early_res_to_bootmem into every setup_node_bootmem. and it takes range that node has. otherwise alloc_bootmem could return addr that reserved early. depends on "mm: make reserve_bootmem can crossed the nodes".
