A process may\nhave migrated to another node. Memory was allocated optimally for the prior\ncontext. sys_migrate_pages allows to shift the memory to the new node.\n\nsys_migrate_pages is also useful if the processes available memory nodes have\nchanged through cpuset operations to manually move the processes memory. Paul\nJackson is working on an automated mechanism that will allow an automatic\nmigration if the cpuset of a process is changed. However, a user may decide\nto manually control the migration.\n\nThis implementation is put into the policy layer since it uses concepts and\nfunctions that are also needed for mbind and friends. The patch also provides\na do_migrate_pages function that may be useful for cpusets to automatically\nmove memory. sys_migrate_pages does not modify policies in contrast to Ray\u0027s\nimplementation.\n\nThe current code here is based on the swap based page migration capability and\nthus is not able to preserve the physical layout relative to it containing\nnodeset (which may be a cpuset). When direct page migration becomes available\nthen the implementation needs to be changed to do a isomorphic move of pages\nbetween different nodesets.

Current\nimplementation supports only shmfs/tmpfs and other filesystems return\n-ENOSYS.\n\n\"Some app allocates large tmpfs files, then when some task quits and some\nclient disconnect, some memory can be released. However the only way to\nrelease tmpfs-swap is to MADV_REMOVE\". - Andrea Arcangeli\n\nDatabases want to use this feature to drop a section of their bufferpool\n(shared memory segments) - without writing back to disk/swap space.\n\nThis feature is also useful for supporting hot-plug memory on UML.\n\nConcerns raised by Andrew Morton:\n\n- \"We have no plan for holepunching! If we _do_ have such a plan (or\n might in the future) then what would the API look like? I think\n sys_holepunch(fd, start, len), so we should start out with that.\"\n\n- Using madvise is very weird, because people will ask \"why do I need to\n mmap my file before I can stick a hole in it?\"\n\n- None of the other madvise operations call into the filesystem in this\n manner. A broad question is: is this capability an MM operation or a\n filesytem operation? truncate, for example, is a filesystem operation\n which sometimes has MM side-effects. madvise is an mm operation and with\n this patch, it gains FS side-effects, only they\u0027re really, really\n significant ones.\"\n\nComments:\n\n- Andrea suggested the fs operation too but then it\u0027s more efficient to\n have it as a mm operation with fs side effects, because they don\u0027t\n immediatly know fd and physical offset of the range. It\u0027s possible to\n fixup in userland and to use the fs operation but it\u0027s more expensive,\n the vmas are already in the kernel and we can use them.\n\nShort term plan \u0026 Future Direction:\n\n- We seem to need this interface only for shmfs/tmpfs files in the short\n term. We have to add hooks into the filesystem for correctness and\n completeness. This is what this patch does.\n\n- In the future, plan is to support both fs and mmap apis also. This\n also involves (other) filesystem specific functions to be implemented.\n\n- Current patch doesn\u0027t support VM_NONLINEAR - which can be addressed in\n the future.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "90933fc8ba5cc9034e3c04ee19938a22b0b4fe4e", "tree": "e42a78d253b375025cf73efe0f582d2722619397", "parents": [ "3821af2fe13700cab6fd67367128fa180e43f8b8" ], "author": { "name": "Stephen Hemminger", "email": "shemminger@osdl.org", "time": "Wed Dec 21 19:31:36 2005 -0800" }, "committer": { "name": "David S.

Both was ruled out at this point because it was in early\n2.4 when VM is still quite shakey and had bad troubles even\ndealing with one DMA zone. We settled on the 16MB DMA zone mainly\nbecause we worried about older soundcards and the floppy.\n\nBut this has always caused problems since then because\ndevice drivers had trouble getting enough DMA able memory. These days\nthe VM works much better and the wide use of NUMA has proven\nit can deal with many zones successfully.\n\nSo this patch adds both zones.\n\nThis helps drivers who need a lot of memory below 4GB because\ntheir hardware is not accessing more (graphic drivers - proprietary\nand free ones, video frame buffer drivers, sound drivers etc.).\nPreviously they could only use IOMMU+16MB GFP_DMA, which\nwas not enough memory.\n\nAnother common problem is that hardware who has full memory\naddressing for \u003e4GB misses it for some control structures in memory\n(like transmit rings or other metadata). They tended to allocate memory\nin the 16MB GFP_DMA or the IOMMU/swiotlb then using pci_alloc_consistent,\nbut that can tie up a lot of precious 16MB GFPDMA/IOMMU/swiotlb memory\n(even on AMD systems the IOMMU tends to be quite small) especially if you have\nmany devices. With the new zone pci_alloc_consistent can just put\nthis stuff into memory below 4GB which works better.\n\nOne argument was still if the zone should be 4GB or 2GB. The main\nmotivation for 2GB would be an unnamed not so unpopular hardware\nraid controller (mostly found in older machines from a particular four letter\ncompany) who has a strange 2GB restriction in firmware. But\nthat one works ok with swiotlb/IOMMU anyways, so it doesn\u0027t really\nneed GFP_DMA32. I chose 4GB to be compatible with IA64 and because\nit seems to be the most common restriction.\n\nThe new zone is so far added only for x86-64.\n\nFor other architectures who don\u0027t set up this\nnew zone nothing changes. Architectures can set a compatibility\ndefine in Kconfig CONFIG_DMA_IS_DMA32 that will define GFP_DMA32\nas GFP_DMA. Otherwise it\u0027s a nop because on 32bit architectures\nit\u0027s normally not needed because GFP_NORMAL (\u003d0) is DMA able\nenough.\n\nOne problem is still that GFP_DMA means different things on different\narchitectures. e.g. some drivers used to have #ifdef ia64 use GFP_DMA\n(trusting it to be 4GB) #elif __x86_64__ (use other hacks like\nthe swiotlb because 16MB is not enough) ... . This was quite\nugly and is now obsolete.\n\nThese should be now converted to use GFP_DMA32 unconditionally. I haven\u0027t done\nthis yet. Or best only use pci_alloc_consistent/dma_alloc_coherent\nwhich will use GFP_DMA32 transparently.\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "8426e1f6af0fd7f44d040af7263750c5a52f3cc3", "tree": "827bd2588c2b73d11cea6869de8ff42dba134375", "parents": [ "4a6dae6d382e9edf3ff440b819e554ed706359bc" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Sun Nov 13 16:07:25 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Nov 13 18:14:16 2005 -0800" }, "message": "[PATCH] atomic: inc_not_zero\n\nIntroduce an atomic_inc_not_zero operation.

The limited global vector space forces us to this right now.\nIn future when interrupts are split into per CPU domains this could be\nfixed, at the cost of needing more IPIs in flat mode.\n\nAlso some minor cleanup in the smp flush code and remove some outdated\ndebug code.\n\nRequires patch to move cpu_possible_map setup earlier.\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "69e1a33f62eff9b228a8cc2c3e4429dbee8966c9", "tree": "985f088d05f2d936cfafa5dd0232aa59391dc663", "parents": [ "413588c7cb8113c03d0044f1d41b832ad7201c29" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Mon Sep 12 18:49:24 2005 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Sep 12 10:49:57 2005 -0700" }, "message": "[PATCH] x86-64: Use ACPI PXM to parse PCI\u003c-\u003enode assignments\n\nSince this is shared code I had to implement it for i386 too\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b9aac10dddd927f0b9cfcca19a272ded87015574", "tree": "4a841306db9b3fb94f7b4ae550cac2c994343dba", "parents": [ "0a43e4bf7489074c667f24b9670ecd88f6eb0a07" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Mon Sep 12 18:49:24 2005 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Sep 12 10:49:57 2005 -0700" }, "message": "[PATCH] x86-64: Remove redundant max_mapnr and replace with end_pfn\n\nThe FLATMEM people added it, but there doesn\u0027t seem a good reason\nbecause end_pfn is identical.\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "6142891a0c0209c91aa4a98f725de0d6e2ed4918", "tree": "42bea8f8c19aeec3a2b5d518f09b7902fe6bf6d1", "parents": [ "357e11d4cbbbb959a88a9bdbbf33a10f160b0823" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Mon Sep 12 18:49:24 2005 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Sep 12 10:49:56 2005 -0700" }, "message": "[PATCH] x86-64: Avoid unnecessary double bouncing for swiotlb\n\nPCI_DMA_BUS_IS_PHYS has to be zero even when the GART IOMMU is disabled\nand the swiotlb is used.

(previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners. There is new spinlock-owner/CPU-tracking on SMP builds too.\nAll locks have lockup detection now, which will work for both soft and hard\nspin/rwlock lockups.\n\nThe arch-level include files now only contain the minimally necessary\nsubset of the spinlock code - all the rest that can be generalized now\nlives in the generic headers:\n\n include/asm-i386/spinlock_types.h | 16\n include/asm-x86_64/spinlock_types.h | 16\n\nI have also split up the various spinlock variants into separate files,\nmaking it easier to see which does what.

I did not try to build\n non-SMP kernels. That should be trivial to fix up later if necessary.\n\n I converted bit ops atomic_hash lock to raw_spinlock_t. Doing so avoids\n some ugly nesting of linux/*.h and asm/*.h files. Those particular locks\n are well tested and contained entirely inside arch specific code. I do NOT\n expect any new issues to arise with them.\n\n If someone does ever need to use debug/metrics with them, then they will\n need to unravel this hairball between spinlocks, atomic ops, and bit ops\n that exist only because parisc has exactly one atomic instruction: LDCW\n (load and clear word).\n\nFrom: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\n\n ia64 fix\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjanv@infradead.org\u003e\nSigned-off-by: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Mikael Pettersson \u003cmikpe@csd.uu.se\u003e\nSigned-off-by: Benoit Boissinot \u003cbenoit.boissinot@ens-lyon.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "486a153f0e294f7cc735838edcb6b32e623cbe52", "tree": "f16a31eb3526968dd08aa93c12cbb211f31f2084", "parents": [ "9c8550ee25e26d14a8f0fe1b761a676e23fe3cf0", "f64a227b6b5cc1f8cc7f6ef9cc3351343636bac9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 09 15:46:49 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 09 15:46:49 2005 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/sam/kbuild \n" }, { "commit": "24b20ac6e1c80082889b3d6ae08aadda777519e5", "tree": "6dd4c90d761f6b8764c4780c298f0bc581af25da", "parents": [ "73a358d1892a8233801e3fd54668075b52ec42da" ], "author": { "name": "Kenji Kaneshige", "email": "kaneshige.kenji@jp.fujitsu.com", "time": "Fri Sep 09 13:02:11 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 09 13:57:33 2005 -0700" }, "message": "[PATCH] remove unnecessary handle_IRQ_event() prototypes\n\nThe function prototype for handle_IRQ_event() in a few architctures is not\nneeded because they use GENERIC_HARDIRQ.\n\nSigned-off-by: Kenji Kaneshige \u003ckaneshige.kenji@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e2d5df935d8a82cb7a2c50726628fa928aa89b9b", "tree": "dd7c5bffa423a57e58b7b3f62432c33521c2e776", "parents": [ "e6ae744dd2eae8e00af328b11b1fe77cb0931136" ], "author": { "name": "Sam Ravnborg", "email": "sam@mars.(none)", "time": "Fri Sep 09 21:28:48 2005 +0200" }, "committer": { "name": "Sam Ravnborg", "email": "sam@mars.(none)", "time": "Fri Sep 09 21:28:48 2005 +0200" }, "message": "kbuild: alpha,x86_64 use generic asm-offsets.h support\n\nDelete obsolete stuff from arch makefiles\nRename .h file to asm-offsets.h\n\nSigned-off-by: Sam Ravnborg \u003csam@ravnborg.org\u003e\n" }, { "commit": "64e47488c913ac704d465a6af86a26786d1412a5", "tree": "d3b0148592963dcde26e4bb35ddfec8b1eaf8e23", "parents": [ "4a35a46bf1cda4737c428380d1db5d15e2590d18", "caf39e87cc1182f7dae84eefc43ca14d54c78ef9" ], "author": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Thu Sep 08 01:45:47 2005 -0400" }, "committer": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Thu Sep 08 01:45:47 2005 -0400" }, "message": "Merge linux-2.6 with linux-acpi-2.6\n" }, { "commit": "5ac353f9baf7169298ebb7de86b2d697b25bca44", "tree": "2591e241e07c96d19db85d418ff6623ec394f984", "parents": [ "1abf62afb6e9cdc1b2618b69067a186b94281587" ], "author": { "name": "Stephen Rothwell", "email": "sfr@canb.auug.org.au", "time": "Tue Sep 06 15:18:00 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:38 2005 -0700" }, "message": "[PATCH] Clean up struct flock definitions\n\nThis patch just gathers together all the struct flock definitions except\nxtensa into asm-generic/fcntl.h.\n\nSigned-off-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1abf62afb6e9cdc1b2618b69067a186b94281587", "tree": "a3e3266a23d8d75bf6c302763327b60b7372a41c", "parents": [ "e64ca97fd80a129e538ca42d0b12c379746b83db" ], "author": { "name": "Stephen Rothwell", "email": "sfr@canb.auug.org.au", "time": "Tue Sep 06 15:17:59 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:38 2005 -0700" }, "message": "[PATCH] Clean up the fcntl operations\n\nThis patch puts the most popular of each fcntl operation/flag into\nasm-generic/fcntl.h and cleans up the arch files.\n\nSigned-off-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ], "next": "e64ca97fd80a129e538ca42d0b12c379746b83db" }
