  "message": "Memoryless nodes: introduce mask of nodes with memory\n\nIt is necessary to know if nodes have memory since we have recently begun to\nadd support for memoryless nodes.  For that purpose we introduce a two new\nnode states: N_HIGH_MEMORY and N_NORMAL_MEMORY.\n\nA node has its bit in N_HIGH_MEMORY set if it has any memory regardless of the\ntype of mmemory.  If a node has memory then it has at least one zone defined\nin its pgdat structure that is located in the pgdat itself.\n\nA node has its bit in N_NORMAL_MEMORY set if it has a lower zone than\nZONE_HIGHMEM.  This means it is possible to allocate memory that is not\nsubject to kmap.\n\nN_HIGH_MEMORY and N_NORMAL_MEMORY can then be used in various places to insure\nthat we do the right thing when we encounter a memoryless node.\n\n[akpm@linux-foundation.org: build fix]\n[Lee.Schermerhorn@hp.com: update N_HIGH_MEMORY node state for memory hotadd]\n[y-goto@jp.fujitsu.com: Fix memory hotplug + sparsemem build]\nSigned-off-by: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\nSigned-off-by: Nishanth Aravamudan \u003cnacc@us.ibm.com\u003e\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nAcked-by: Bob Picco \u003cbob.picco@hp.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Mel Gorman \u003cmel@skynet.ie\u003e\nSigned-off-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
