Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed.

Some structures of memory management are allocated by\nbootmem. ex) memmap, etc.\n\nTo remove memory physically, some of them must be freed according to\ncircumstance. 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). When the section is\nremoving, kernel can confirm it. By this information, some issues can be\nsolved.\n\n 1) When the memmap of removing section is allocated on other\n section by bootmem, it should/can be free.\n 2) When the memmap of removing section is allocated on the\n same section, it shouldn\u0027t be freed. 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, it will be able to do by this patch.\n (Not implemented yet.)\n 5) The node information like pgdat has similar issues. 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. Kernel can\ndistinguish which node/section uses the pages allcated by bootmem.

This kind of\nmem_map[] is needed by discontiguous memory machines (like in the old\nCONFIG_DISCONTIGMEM case) as well as memory hotplug systems. Sparsemem\nreplaces DISCONTIGMEM when enabled, and it is hoped that it can eventually\nbecome a complete replacement.\n\nA significant advantage over DISCONTIGMEM is that it\u0027s completely separated\nfrom CONFIG_NUMA. When producing this patch, it became apparent in that NUMA\nand DISCONTIG are often confused.\n\nAnother advantage is that sparse doesn\u0027t require each NUMA node\u0027s ranges to be\ncontiguous. It can handle overlapping ranges between nodes with no problems,\nwhere DISCONTIGMEM currently throws away that memory.\n\nSparsemem uses an array to provide different pfn_to_page() translations for\neach SECTION_SIZE area of physical memory. This is what allows the mem_map[]\nto be chopped up.\n\nIn order to do quick pfn_to_page() operations, the section number of the page\nis encoded in page-\u003eflags. Part of the sparsemem infrastructure enables\nsharing of these bits more dynamically (at compile-time) between the\npage_zone() and sparsemem operations. However, on 32-bit architectures, the\nnumber of bits is quite limited, and may require growing the size of the\npage-\u003eflags type in certain conditions. Several things might force this to\noccur: a decrease in the SECTION_SIZE (if you want to hotplug smaller areas of\nmemory), an increase in the physical address space, or an increase in the\nnumber of used page-\u003eflags.\n\nOne thing to note is that, once sparsemem is present, the NUMA node\ninformation no longer needs to be stored in the page-\u003eflags. It might provide\nspeed increases on certain platforms and will be stored there if there is\nroom. But, if out of room, an alternate (theoretically slower) mechanism is\nused.\n\nThis patch introduces CONFIG_FLATMEM. It is used in almost all cases where\nthere used to be an #ifndef DISCONTIG, because SPARSEMEM and DISCONTIGMEM\noften have to compile out the same areas of code.\n\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nSigned-off-by: Martin Bligh \u003cmbligh@aracnet.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nSigned-off-by: Bob Picco \u003cbob.picco@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
