Unfortunately for hot-added\nmemory the zones \"grow\" after the memmap and the pageblock memmap have\nbeen initialized. Which means that the new pages have an unitialized\nbitmap. To solve this the calls to grow_zone_span() and grow_pgdat_span()\nare moved to __add_zone() just before the initialization happens.\n\nThe patch also moves the two functions since __add_zone() is the only\ncaller and I didn\u0027t want to add a forward declaration.\n\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nCc: Gerald Schaefer \u003cgerald.schaefer@de.ibm.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fd8a4221ad76df700ff34875c9fbc42302aa4ba3", "tree": "4f37586cef40dca7cc8b630e85965a698e3aa1be", "parents": [ "3fc957721d18c93662f7d4dab455b80f53dd2641" ], "author": { "name": "Geoff Levand", "email": "geoffrey.levand@am.sony.com", "time": "Wed May 14 16:05:50 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 14 19:11:14 2008 -0700" }, "message": "memory_hotplug: check for walk_memory_resource() failure in online_pages()\n\nAdd a check to online_pages() to test for failure of\nwalk_memory_resource().

This patch set makes basis to free those pages, and free\nmemmaps.\n\nBasic my idea is using remain members of struct page to remember information\nof users of bootmem (section number or node id).

Because the section has to be\n logical memory offlined already and all pages must be isolated against\n page allocater. If it is freed, page allocator may use it which will\n be removed physically soon.\n 3) When removing section has other section\u0027s memmap,\n kernel will be able to show easily which section should be removed\n before it for user. (Not implemented yet)\n 4) When the above case 2), the page isolation will be able to check and skip\n memmap\u0027s page when logical memory offline (offline_pages()).\n Current page isolation code fails in this case because this page is\n just reserved page and it can\u0027t distinguish this pages can be\n removed or not.

But, this\n will be able to be solved too by this.\n (Not implemented yet, but, remembering node id in the pages.)\n\nFortunately, current bootmem allocator just keeps PageReserved flags,\nand doesn\u0027t use any other members of page struct. The users of\nbootmem doesn\u0027t use them too.\n\nThis patch:\n\nThis is to register information which is node or section\u0027s id.

Make this top cpus file read-only.\n\nOn systems that have cpusets configured in their kernel, but that aren\u0027t\nactively using cpusets (for some distros, this covers the majority of\nsystems) all tasks end up in the top cpuset.\n\nIf that system does support memory hotplug, then these tasks cannot make\nuse of memory nodes that are added after system boot, because the memory\nnodes are not allowed in the top cpuset. This is a surprising regression\nover earlier kernels that didn\u0027t have cpusets enabled.\n\nOne key motivation for this change is to remain consistent with the\nbehaviour for the top_cpuset\u0027s \u0027cpus\u0027, which is also read-only, and which\nautomatically tracks the cpu_online_map.\n\nThis change also has the minor benefit that it fixes a long standing,\nlittle noticed, minor bug in cpusets. The cpuset performance tweak to\nshort circuit the cpuset_zone_allowed() check on systems with just a single\ncpuset (see \u0027number_of_cpusets\u0027, in linux/cpuset.h) meant that simply\nchanging the \u0027mems\u0027 of the top_cpuset had no affect, even though the change\n(the write system call) appeared to succeed. With the following change,\nthat write to the \u0027mems\u0027 file fails -EACCES, and the \u0027mems\u0027 file stubbornly\nrefuses to be changed via user space writes. Thus no one should be mislead\ninto thinking they\u0027ve changed the top_cpusets\u0027s \u0027mems\u0027 when in affect they\nhaven\u0027t.\n\nIn order to keep the behaviour of cpusets consistent between systems\nactively making use of them and systems not using them, this patch changes\nthe behaviour of the \u0027mems\u0027 file in the top (root) cpuset, making it read\nonly, and making it automatically track the value of node_online_map. Thus\ntasks in the top cpuset will have automatic use of hot plugged memory nodes\nallowed by their cpuset.\n\n[akpm@osdl.org: build fix]\n[bunk@stusta.de: build fix]\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ebd15302dc0ba1b8761600c20854f5371e7bae1e", "tree": "af9dc4b9c1c840fcdcd7d1a4053ba0e05eb1f028", "parents": [ "5d2870faaa1fdcec795a6bf4dbbfc3e5d57fd7ab" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Sat Aug 05 12:15:06 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Aug 06 08:57:49 2006 -0700" }, "message": "[PATCH] memory hotadd fixes: enhance collision check\n\nThis patch is for collision check enhancement for memory hot add.\n\nIt\u0027s better to do resouce collision check before doing memory hot add,\nwhich will touch memory management structures.\n\nAnd add_section() should check section exists or not before calling\nsparse_add_one_section().
