It does the following\nthings:\n\n - consolidates and enhances the spinlock/rwlock debugging code\n\n - simplifies the asm/spinlock.h files\n\n - encapsulates the raw spinlock type and moves generic spinlock\n features (such as -\u003ebreak_lock) into the generic code.\n\n - cleans up the spinlock code hierarchy to get rid of the spaghetti.\n\nMost notably there\u0027s now only a single variant of the debugging code,\nlocated in lib/spinlock_debug.c. (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 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": "7bbedd521310547ca73cc77adcf61fb85723adc3", "tree": "f759d90c46bfbc48a9f396c9c6f839da11cdc6aa", "parents": [ "f44702f49056c203341badaa2cb8a706160d9119", "a04ce0ffcaf561994ecf382cd3caad75556dc499" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Sep 08 15:55:23 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Sep 08 15:55:23 2005 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/gregkh/pci-2.6 \n" }, { "commit": "085ae41f66657a9655ce832b0a61832a06f0e1dc", "tree": "215690b947b14fa18cbb2810db1a4082ad607e7a", "parents": [ "064b53dbcc977dbf2753a67c2b8fc1c061d74f21" ], "author": { "name": "David S.

These resources get linked into the\n iomem/ioport tree when PCI controllers are probed.\n\n So the hierarchy looks like this:\n\n iomem --|\n\t PCI controller 1 MEM space --|\n\t\t\t\t device 1\n\t\t\t\t\tdevice 2\n\t\t\t\t\tetc.\n\t PCI controller 2 MEM space --|\n\t\t\t\t ...\n ioport --|\n PCI controller 1 IO space --|\n\t\t\t\t\t...\n PCI controller 2 IO space --|\n\t\t\t\t\t...\n\n You get the idea. The drivers/pci/setup-res.c code allocates\n using plain iomem_space and ioport_space as the root, so that\n wouldn\u0027t work with the above setup.\n\n So I added a pcibios_select_root() that is used to handle this.\n It uses the PCI controller struct\u0027s io_space and mem_space on\n sparc64, and io{port,mem}_resource on every other platform to\n keep current behavior.\n\n2) quirk_io_region() is buggy. It takes in raw BUS view addresses\n and tries to use them as a PCI resource.\n\n pci_claim_resource() expects the resource to be fully formed when\n it gets called. The sparc64 implementation would do the translation\n but that\u0027s absolutely wrong, because if the same resource gets\n released then re-claimed we\u0027ll adjust things twice.\n\n So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()\n conversion before passing it on to pci_claim_resource().\n\n3) I was mistakedly __init\u0027ing the function methods the PCI controller\n drivers provide on sparc64 to implement some parts of these\n routines. This was, of course, easy to fix.\n\nSo we end up with the following, and that nasty SPARC64 makefile\nifdef in drivers/pci/Makefile is finally zapped.\n\nSigned-off-by: David S.

So it goes to sleep and eventually\nthe signalling thread is scheduled in, unlocks the internal lock and wakes\nthe waiter again.\n\nNow, before 2003-09-21 NPTL was using FUTEX_REQUEUE in pthread_cond_signal\nto avoid this performance issue, but it was removed when locks were\nredesigned to the 3 state scheme (unlocked, locked uncontended, locked\ncontended).\n\nFollowing scenario shows why simply using FUTEX_REQUEUE in\npthread_cond_signal together with using lll_mutex_unlock_force in place of\nlll_mutex_unlock is not enough and probably why it has been disabled at\nthat time:\n\nThe number is value in cv-\u003e__data.__lock.\n thr1 thr2 thr3\n0 pthread_cond_wait\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n0 lll_mutex_unlock (cv-\u003e__data.__lock)\n0 lll_futex_wait (\u0026cv-\u003e__data.__futex, futexval)\n0 pthread_cond_signal\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n1 pthread_cond_signal\n2 lll_mutex_lock (cv-\u003e__data.__lock)\n2 lll_futex_wait (\u0026cv-\u003e__data.__lock, 2)\n2 lll_futex_requeue (\u0026cv-\u003e__data.__futex, 0, 1, \u0026cv-\u003e__data.__lock)\n # FUTEX_REQUEUE, not FUTEX_CMP_REQUEUE\n2 lll_mutex_unlock_force (cv-\u003e__data.__lock)\n0 cv-\u003e__data.__lock \u003d 0\n0 lll_futex_wake (\u0026cv-\u003e__data.__lock, 1)\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n0 lll_mutex_unlock (cv-\u003e__data.__lock)\n # Here, lll_mutex_unlock doesn\u0027t know there are threads waiting\n # on the internal cv\u0027s lock\n\nNow, I believe it is possible to use FUTEX_REQUEUE in pthread_cond_signal,\nbut it will cost us not one, but 2 extra syscalls and, what\u0027s worse, one of\nthese extra syscalls will be done for every single waiting loop in\npthread_cond_*wait.\n\nWe would need to use lll_mutex_unlock_force in pthread_cond_signal after\nrequeue and lll_mutex_cond_lock in pthread_cond_*wait after lll_futex_wait.\n\nAnother alternative is to do the unlocking pthread_cond_signal needs to do\n(the lock can\u0027t be unlocked before lll_futex_wake, as that is racy) in the\nkernel.\n\nI have implemented both variants, futex-requeue-glibc.patch is the first\none and futex-wake_op{,-glibc}.patch is the unlocking inside of the kernel.\n The kernel interface allows userland to specify how exactly an unlocking\noperation should look like (some atomic arithmetic operation with optional\nconstant argument and comparison of the previous futex value with another\nconstant).\n\nIt has been implemented just for ppc*, x86_64 and i?86, for other\narchitectures I\u0027m including just a stub header which can be used as a\nstarting point by maintainers to write support for their arches and ATM\nwill just return -ENOSYS for FUTEX_WAKE_OP. The requeue patch has been\n(lightly) tested just on x86_64, the wake_op patch on ppc64 kernel running\n32-bit and 64-bit NPTL and x86_64 kernel running 32-bit and 64-bit NPTL.\n\nWith the following benchmark on UP x86-64 I get:\n\nfor i in nptl-orig nptl-requeue nptl-wake_op; do echo time elf/ld.so --library-path .:$i /tmp/bench; \\\nfor j in 1 2; do echo ( time elf/ld.so --library-path .:$i /tmp/bench ) 2\u003e\u00261; done; done\ntime elf/ld.so --library-path .:nptl-orig /tmp/bench\nreal 0m0.655s user 0m0.253s sys 0m0.403s\nreal 0m0.657s user 0m0.269s sys 0m0.388s\ntime elf/ld.so --library-path .:nptl-requeue /tmp/bench\nreal 0m0.496s user 0m0.225s sys 0m0.271s\nreal 0m0.531s user 0m0.242s sys 0m0.288s\ntime elf/ld.so --library-path .:nptl-wake_op /tmp/bench\nreal 0m0.380s user 0m0.176s sys 0m0.204s\nreal 0m0.382s user 0m0.175s sys 0m0.207s\n\nThe benchmark is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00001.txt\nOlder futex-requeue-glibc.patch version is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00002.txt\nOlder futex-wake_op-glibc.patch version is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00003.txt\nWill post a new version (just x86-64 fixes so that the patch\napplies against pthread_cond_signal.S) to libc-hacker ml soon.\n\nAttached is the kernel FUTEX_WAKE_OP patch as well as a simple-minded\ntestcase that will not test the atomicity of the operation, but at least\ncheck if the threads that should have been woken up are woken up and\nwhether the arithmetic operation in the kernel gave the expected results.\n\nAcked-by: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Jamie Lokier \u003cjamie@shareable.org\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Yoichi Yuasa \u003cyuasa@hh.iij4u.or.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e766f1cc596078b1603ac2c96617660c4c7e2d81", "tree": "86f24a621dbe39fd25dcec539c2f969f50bfbcab", "parents": [ "48467641bcc057f7cba3b6cbbe66cb834d64cc81", "ebede60741e2cec6d210f137fd22a30e37abc0be" ], "author": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:12:58 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:12:58 2005 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6 \n" }, { "commit": "fa5b08d5f818063d18433194f20359ef2ae50254", "tree": "f2b2bc88347a618f0c4b535d57d2a5271a5eb98e", "parents": [ "0e5c9f39f64d8a55c5db37a5ea43e37d3422fd92" ], "author": { "name": "Kyle Moffett", "email": "mrmacman_g4@mac.com", "time": "Sat Sep 03 15:55:03 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:05:48 2005 -0700" }, "message": "[PATCH] sab: consolidate kmem_bufctl_t\n\nThis is used only in slab.c and each architecture gets to define whcih\nunderlying type is to be used.\n\nSeems a bit silly - move it to slab.c and use the same type for all\narchitectures: unsigned int.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fd4fd5aac1282825195c6816ed40a2a6d42db5bf", "tree": "5908cf4c88a7c9d69ea7bdc1c354d51b6ff47f86", "parents": [ "28ae55c98e4d16eac9a05a8a259d7763ef3aeb18" ], "author": { "name": "Stephen Rothwell", "email": "sfr@canb.auug.org.au", "time": "Sat Sep 03 15:54:30 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:05:39 2005 -0700" }, "message": "[PATCH] mm: consolidate get_order\n\nSomeone mentioned that almost all the architectures used basically the same\nimplementation of get_order.

There are three forms of the advice:\n\n1) Burst as much as possible, it is not necessary to end bursts\n on some particular boundary for best performance.\n\n2) Burst on some byte count multiple. A DMA burst to some multiple of\n number of bytes may be done, but it is important to end the burst\n on an exact multiple for best performance.\n\n The best example of this I am aware of are the PPC64 PCI\n controllers, where if you end a burst mid-cacheline then\n chip has to refetch the data and the IOMMU translations\n which hurts performance a lot.\n\n3) Burst on a single byte count multiple. Bursts shall end\n exactly on the next multiple boundary for best performance.\n\n Sparc64 and Alpha\u0027s PCI controllers operate this way. They\n disconnect any device which tries to burst across a cacheline\n boundary.\n\n Actually, newer sparc64 PCI controllers do not have this behavior.\n That is why the \"pdev\" is passed into the interface, so I can\n add code later to check which PCI controller the system is using\n and give advice accordingly.\n\nSigned-off-by: David S.

As before, synchronize_rcu() would not cut it...\n\n- include/linux/list.h comment: change to synchronize_rcu(), since this\n comment is for list_del_rcu().\n\n- security/keys/key.c unregister_key_type(): change to synchronize_rcu(),\n since this is interacting with RCU read side.\n\n- security/keys/process_keys.c install_session_keyring(): change to\n synchronize_rcu(), since this is interacting with RCU read side.\n\nSigned-off-by: \"Paul E.
