But Linux runs only on\n32-bit and wider CPUs. We can use that.\n\nFirst: using 32x32-\u003e64 multiply and trivial 32-bit shift, we can correctly\ndivide by 10 much larger numbers, and thus we can print groups of 9 digits\ninstead of groups of 5 digits.\n\nNext: there are two algorithms to print larger numbers. One is generic:\ndivide by 1000000000 and repeatedly print groups of (up to) 9 digits.\nIt\u0027s conceptually simple, but requires an (unsigned long long) /\n1000000000 division.\n\nSecond algorithm splits 64-bit unsigned long long into 16-bit chunks,\nmanipulates them cleverly and generates groups of 4 decimal digits. It so\nhappens that it does NOT require long long division.\n\nIf long is \u003e 32 bits, division of 64-bit values is relatively easy, and we\nwill use the first algorithm. If long long is \u003e 64 bits (strange\narchitecture with VERY large long long), second algorithm can\u0027t be used,\nand we again use the first one.\n\nElse (if long is 32 bits and long long is 64 bits) we use second one.\n\nAnd third: there is a simple optimization which takes fast path not only\nfor zero as was done before, but for all one-digit numbers.\n\nIn all tested cases new code is faster than old one, in many cases by 30%,\nin few cases by more than 50% (for example, on x86-32, conversion of\n12345678).

For example, if you can rely on a fast population\ncount instruction on your architecture, this will allow you to make your\noptimized \u003casm/word-at-a-time.h\u003e file with that.\n\nNOTE! The \"generic\" version in include/asm-generic/word-at-a-time.h is\nnot truly generic, it actually only works on big-endian. Why? Because\non little-endian the generic algorithms are wasteful, since you can\ninevitably do better. The x86 implementation is an example of that.\n\n(The only truly non-generic part of the asm-generic implementation is\nthe \"find_zero()\" function, and you could make a little-endian version\nof it. And if the Kbuild infrastructure allowed us to pick a particular\nheader file, that would be lovely)\n\nThe \u003casm/word-at-a-time.h\u003e functions are as follows:\n\n - WORD_AT_A_TIME_CONSTANTS: specific constants that the algorithm\n uses.\n\n - has_zero(): take a word, and determine if it has a zero byte in it.\n It gets the word, the pointer to the constant pool, and a pointer to\n an intermediate \"data\" field it can set.\n\n This is the \"quick-and-dirty\" zero tester: it\u0027s what is run inside\n the hot loops.\n\n - \"prep_zero_mask()\": take the word, the data that has_zero() produced,\n and the constant pool, and generate an *exact* mask of which byte had\n the first zero. This is run directly *outside* the loop, and allows\n the \"has_zero()\" function to answer the \"is there a zero byte\"\n question without necessarily getting exactly *which* byte is the\n first one to contain a zero.\n\n If you do multiple byte lookups concurrently (eg \"hash_name()\", which\n looks for both NUL and \u0027/\u0027 bytes), after you\u0027ve done the prep_zero_mask()\n phase, the result of those can be or\u0027ed together to get the \"either\n or\" case.\n\n - The result from \"prep_zero_mask()\" can then be fed into \"find_zero()\"\n (to find the byte offset of the first byte that was zero) or into\n \"zero_bytemask()\" (to find the bytemask of the bytes preceding the\n zero byte).\n\n The existence of zero_bytemask() is optional, and is not necessary\n for the normal string routines. But dentry name hashing needs it, so\n if you enable DENTRY_WORD_AT_A_TIME you need to expose it.\n\nThis changes the generic strncpy_from_user() function and the dentry\nhashing functions to use these modified word-at-a-time interfaces. This\ngets us back to the optimized state of the x86 strncpy that we lost in\nthe previous commit when moving over to the generic version.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ce004178be1bbaa292e9e6497939e2970300095a", "tree": "1cd5306548947deaedd612189b56d35265217e8e", "parents": [ "9978306e31a8f89bd81fbc4c49fd9aefb1d30d10", "c5389831cda3b38a56606a348a537a1332f2d729" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 24 15:10:28 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 24 15:10:28 2012 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc\n\nPull sparc changes from David S.

McKenney:\n\n 1) A set of improvements and fixes to the RCU_FAST_NO_HZ feature (with\n more on the way for 3.6). Posted to LKML:\n https://lkml.org/lkml/2012/4/23/324 (commits 1-3 and 5),\n https://lkml.org/lkml/2012/4/16/611 (commit 4),\n https://lkml.org/lkml/2012/4/30/390 (commit 6), and\n https://lkml.org/lkml/2012/5/4/410 (commit 7, combined with\n the other commits for the convenience of the tester).\n\n 2) Changes to make rcu_barrier() avoid disrupting execution of CPUs\n that have no RCU callbacks. Posted to LKML:\n https://lkml.org/lkml/2012/4/23/322.\n\n 3) A couple of commits that improve the efficiency of the interaction\n between preemptible RCU and the scheduler, these two being all that\n survived an abortive attempt to allow preemptible RCU\u0027s\n __rcu_read_lock() to be inlined. The full set was posted to LKML at\n https://lkml.org/lkml/2012/4/14/143, and the first and third patches\n of that set remain.\n\n 4) Lai Jiangshan\u0027s algorithmic implementation of SRCU, which includes\n call_srcu() and srcu_barrier(). A major feature of this new\n implementation is that synchronize_srcu() no longer disturbs the\n execution of other CPUs. This work is based on earlier\n implementations by Peter Zijlstra and Paul E. McKenney. Posted to\n LKML: https://lkml.org/lkml/2012/2/22/82.\n\n 5) A number of miscellaneous bug fixes and improvements which were\n posted to LKML at: https://lkml.org/lkml/2012/4/23/353 with\n subsequent updates posted to LKML.\"\n\n* \u0027core-rcu-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (32 commits)\n rcu: Make rcu_barrier() less disruptive\n rcu: Explicitly initialize RCU_FAST_NO_HZ per-CPU variables\n rcu: Make RCU_FAST_NO_HZ handle timer migration\n rcu: Update RCU maintainership\n rcu: Make exit_rcu() more precise and consolidate\n rcu: Move PREEMPT_RCU preemption to switch_to() invocation\n rcu: Ensure that RCU_FAST_NO_HZ timers expire on correct CPU\n rcu: Add rcutorture test for call_srcu()\n rcu: Implement per-domain single-threaded call_srcu() state machine\n rcu: Use single value to handle expedited SRCU grace periods\n rcu: Improve srcu_readers_active_idx()\u0027s cache locality\n rcu: Remove unused srcu_barrier()\n rcu: Implement a variant of Peter\u0027s SRCU algorithm\n rcu: Improve SRCU\u0027s wait_idx() comments\n rcu: Flip -\u003ecompleted only once per SRCU grace period\n rcu: Increment upper bit only for srcu_read_lock()\n rcu: Remove fast check path from __synchronize_srcu()\n rcu: Direct algorithmic SRCU implementation\n rcu: Introduce rcutorture testing for rcu_barrier()\n timer: Fix mod_timer_pinned() header comment\n ...\n" }, { "commit": "513de477a09f770e42ad042bf830565d9c73a158", "tree": "5a9924a8bffb4777d3df34ce2b05d564f3b567b6", "parents": [ "62c8d922783a0fa41a9b4ca004f0467d6ca9be48", "3340808cf04faad7b87d6c6e13800825e5552b51" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon May 21 19:22:55 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon May 21 19:22:55 2012 -0700" }, "message": "Merge branch \u0027core-debugobjects-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull core/debugobjects changes from Ingo Molnar:\n \"Not much happened: it includes a cleanup and an irq latency reduction\n fixlet.\"\n\n* \u0027core-debugobjects-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:\n debugobjects: Fill_pool() returns void now\n debugobjects: printk with irqs enabled\n debugobjects: Remove unused return value from fill_pool()\n" }, { "commit": "6684b5729df289ba60a404d8d095d820dc553cdf", "tree": "69f52bdad9a836c00b93fab95b361a86f1555684", "parents": [ "3d4f5eb1264a1d3aa4aa19502d8c588b3cc4ecc4" ], "author": { "name": "Oskar Schirmer", "email": "oskar@scara.com", "time": "Wed May 16 09:41:19 2012 +0000" }, "committer": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Thu May 17 15:18:37 2012 +0200" }, "message": "lib: Change mail address of Oskar Schirmer\n\nThat old mail address doesnt exist any more.\nThis changes all occurences to my new address.\n\nSigned-off-by: Oskar Schirmer \u003coskar@scara.com\u003e\nCc: Paul Gortmaker \u003cpaul.gortmaker@windriver.com\u003e\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\n" }, { "commit": "649e6ee33f73ba1c4f2492c6de9aff2254b540cb", "tree": "f7fe1b11f4eb7c306a07a8893980a5d34a0886d9", "parents": [ "5c5d5ca51abd728c8de3be43ffd6bb00f977bfcd" ], "author": { "name": "Kay Sievers", "email": "kay@vrfy.org", "time": "Thu May 10 04:30:45 2012 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Wed May 09 20:35:06 2012 -0700" }, "message": "printk() - restore timestamp printing at console output\n\nThe output of the timestamps got lost with the conversion of the\nkmsg buffer to records;

Its based upon\nThomas Renninger\u0027s $module.ddebug boot-time debugging patch from\nhttps://lkml.org/lkml/2010/9/15/397\n\nThe \u0027fake\u0027 module parameter is provided for all modules, whether or\nnot they need it. It is not explicitly added to each module, but is\nimplemented in callbacks invoked from parse_args.\n\nFor builtin modules, dynamic_debug_init() now directly calls\nparse_args(..., \u0026ddebug_dyndbg_boot_params_cb), to process the params\nundeclared in the modules, just after the ddebug tables are processed.\n\nWhile its slightly weird to reprocess the boot params, parse_args() is\nalready called repeatedly by do_initcall_levels(). More importantly,\nthe dyndbg queries (given in ddebug_query or dyndbg params) cannot be\nactivated until after the ddebug tables are ready, and reusing\nparse_args is cleaner than doing an ad-hoc parse. This reparse would\nbreak options like inc_verbosity, but they probably should be params,\nlike verbosity\u003d3.\n\nddebug_dyndbg_boot_params_cb() handles both bare dyndbg (aka:\nddebug_query) and module-prefixed dyndbg params, and ignores all other\nparameters. For example, the following will enable pr_debug()s in 4\nbuiltin modules, in the order given:\n\n dyndbg\u003d\"module params +p; module aio +p\" module.dyndbg\u003d+p pci.dyndbg\n\nFor loadable modules, parse_args() in load_module() calls\nddebug_dyndbg_module_params_cb(). This handles bare dyndbg params as\npassed from modprobe, and errors on other unknown params.\n\nNote that modprobe reads /proc/cmdline, so \"modprobe foo\" grabs all\nfoo.params, strips the \"foo.\", and passes these to the kernel.\nddebug_dyndbg_module_params_cb() is again called for the unknown\nparams; it handles dyndbg, and errors on others. The \"doing\" arg\nadded previously contains the module name.\n\nFor non CONFIG_DYNAMIC_DEBUG builds, the stub function accepts\nand ignores $module.dyndbg params, other unknowns get -ENOENT.\n\nIf no param value is given (as in pci.dyndbg example above), \"+p\" is\nassumed, which enables all pr_debug callsites in the module.\n\nThe dyndbg fake parameter is not shown in /sys/module/*/parameters,\nthus it does not use any resources.

It might as well be since we only assign to it once and use it\nas a constant, and then the compiler will tell us if we ever assign to\nit in the future.\n\nSigned-off-by: Jesper Juhl \u003cjj@chaosbits.net\u003e\nAcked-by: Dmitry Kasatkin \u003cdmitry.kasatkin@intel.com\u003e\nSigned-off-by: James Morris \u003cjames.l.morris@oracle.com\u003e\n" }, { "commit": "29cdd4e4ec91aae239192bb122d377d15a9d75e3", "tree": "2407fb9f3c7144d110029ad7d32328dee45758bc", "parents": [ "0034102808e0dbbf3a2394b82b1bb40b5778de9e" ], "author": { "name": "Jakub Kicinski", "email": "kubakici@wp.pl", "time": "Wed Apr 04 03:19:10 2012 +0200" }, "committer": { "name": "Joerg Roedel", "email": "joerg.roedel@amd.com", "time": "Thu Apr 12 12:28:46 2012 +0200" }, "message": "dma-debug: release free_entries_lock before saving stack trace\n\nSaving stack trace can take a while and once the entry\nis allocated free_entries_lock is no longer needed.\n\nSigned-off-by: Jakub Kicinski \u003ckubakici@wp.pl\u003e\nSigned-off-by: Joerg Roedel \u003cjoerg.roedel@amd.com\u003e\n" }, { "commit": "765a5e0cb581ef32646f58a213b38b56c77709b0", "tree": "a26024288f0dba86084adc716bb4e0f82b155b04", "parents": [ "1fda107d44de1e8df2bdfd1d4a2c12a338b8d725" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Apr 11 11:54:27 2012 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Apr 11 11:56:17 2012 +0200" }, "message": "debugobjects: printk with irqs enabled\n\nNo point in keeping interrupts disabled here.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "1fda107d44de1e8df2bdfd1d4a2c12a338b8d725", "tree": "c15e86b196d23d8328f0d101170bd07057214b27", "parents": [ "923e9a1399b620d063cd88537c64561bc3d5f905" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Apr 11 11:52:18 2012 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Apr 11 11:56:17 2012 +0200" }, "message": "debugobjects: Remove unused return value from fill_pool()\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "282029c005e65ffdce3aa9f8220f88a8bbbc4dae", "tree": "48d488d453def3bd1c408aed1bd4bb4e18115b4c", "parents": [ "3a198886ab5f228fcbebb9ace803d8b99721d49a" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Fri Apr 06 13:41:15 2012 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Tue Apr 10 14:48:51 2012 -0700" }, "message": "kobject: provide more diagnostic info for kobject_add_internal() failures\n\n1/ convert open-coded KERN_ERR+dump_stack() to WARN(), so that automated\n tools pick up this warning.\n\n2/ include the \u0027child\u0027 and \u0027parent\u0027 kobject names.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

As a band-aid, kernel.h\n was including \u003casm/bug.h\u003e to pseudo link them.\n\n This has caused confusion[1] and general yuck/WTF[2] reactions.

It removes the crc32c implementation\nin crypto/ in favor of using the stamped-out one in lib/. There is also\na change to Kconfig so that the kernel builder can pick an\nimplementation best suited for the hardware.\n\nThe motivation for this patchset is that I am working on adding full\nmetadata checksumming to ext4. As far as performance impact of adding\nchecksumming goes, I see nearly no change with a standard mail server\nffsb simulation. On a test that involves only file creation and\ndeletion and extent tree writes, I see a drop of about 50 pcercent with\nthe current kernel crc32c implementation; this improves to a drop of\nabout 20 percent with the enclosed crc32c code.\n\nWhen metadata is usually a small fraction of total IO, this new\nimplementation doesn\u0027t help much because metadata is usually a small\nfraction of total IO. However, when we are doing IO that is almost all\nmetadata (such as rm -rf\u0027ing a tree), then this patch speeds up the\noperation substantially.\n\nIncidentally, given that iscsi, sctp, and btrfs also use crc32c, this\npatchset should improve their speed as well. I have not yet quantified\nthat, however. This latest submission combines Bob\u0027s patches from late\nAugust 2011 with mine so that they can be one coherent patch set.\nPlease excuse my inability to combine some of the patches; I\u0027ve been\nadvised to leave Bob\u0027s patches alone and build atop them instead. :/\n\nSince the last posting, I\u0027ve also collected some crc32c test results on\na bunch of different x86/powerpc/sparc platforms. The results can be\nviewed here: http://goo.gl/sgt3i ; the \"crc32-kern-le\" and \"crc32c\"\ncolumns describe the performance of the kernel\u0027s current crc32 and\ncrc32c software implementations. The \"crc32c-by8-le\" column shows\ncrc32c performance with this patchset applied. I expect crc32\nperformance to be roughly the same.\n\nThe two _boost columns at the right side of the spreadsheet shows how much\nfaster the new implementation is over the old one. As you can see, crc32\nrises substantially, and crc32c experiences a huge increase.\n\nThis patch:\n\n- remove trailing whitespace from lib/crc32.c\n- remove trailing whitespace from lib/crc32defs.h\n\n[djwong@us.ibm.com: changelog tweaks]\nSigned-off-by: Bob Pearson \u003crpearson@systemfabricworks.com\u003e\nSigned-off-by: Darrick J.
