      "message": "tracehook: add linux/tracehook.h\n\nThis patch series introduces the \"tracehook\" interface layer of inlines in\n\u003clinux/tracehook.h\u003e.  There are more details in the log entry for patch\n01/23 and in the header file comments inside that patch.  Most of these\nchanges move code around with little or no change, and they should not\nbreak anything or change any behavior.\n\nThis sets a new standard for uniform arch support to enable clean\narch-independent implementations of new debugging and tracing stuff,\ndenoted by CONFIG_HAVE_ARCH_TRACEHOOK.  Patch 20/23 adds that symbol to\narch/Kconfig, with comments listing everything an arch has to do before\nsetting \"select HAVE_ARCH_TRACEHOOK\".  These are elaborted a bit at:\n\n\thttp://sourceware.org/systemtap/wiki/utrace/arch/HowTo\n\nThe new inlines that arch code must define or call have detailed kerneldoc\ncomments in the generic header files that say what is required.\n\nNo arch is obligated to do any work, and no arch\u0027s build should be broken\nby these changes.  There are several steps that each arch should take so\nit can set HAVE_ARCH_TRACEHOOK.  Most of these are simple.  Providing this\nsupport will let new things people add for doing debugging and tracing of\nuser-level threads \"just work\" for your arch in the future.  For an arch\nthat does not provide HAVE_ARCH_TRACEHOOK, some new options for such\nfeatures will not be available for config.\n\nI have done some arch work and will submit this to the arch maintainers\nafter the generic tracehook series settles in.  For now, that work is\navailable in my GIT repositories, and in patch and mbox-of-patches form at\nhttp://people.redhat.com/roland/utrace/2.6-current/\n\nThis paves the way for my \"utrace\" work, to be submitted later.  But it is\nnot innately tied to that.  I hope that the tracehook series can go in\nsoon regardless of what eventually does or doesn\u0027t go on top of it.  For\nanyone implementing any kind of new tracing/debugging plan, or just\nunderstanding all the context of the existing ptrace implementation,\nhaving tracehook.h makes things much easier to find and understand.\n\nThis patch:\n\nThis adds the new kernel-internal header file \u003clinux/tracehook.h\u003e.  This\nis not yet used at all.  The comments in the header introduce what the\nfollowing series of patches is about.\n\nThe aim is to formalize and consolidate all the places that the core\nkernel code and the arch code now ties into the ptrace implementation.\n\nThese patches mostly don\u0027t cause any functional change.  They just move\nthe details of ptrace logic out of core code into tracehook.h inlines,\nwhere they are mostly compiled away to the same as before.  All that\nchanges is that everything is thoroughly documented and any future\nreworking of ptrace, or addition of something new, would not have to touch\ncore code all over, just change the tracehook.h inlines.\n\nThe new linux/ptrace.h inlines are used by the following patches in the\nnew tracehook_*() inlines.  Using these helpers for the ptrace event stops\nmakes it simple to change or disable the old ptrace implementation of\nthese stops conditionally later.\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nReviewed-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Page table existence is guaranteed by\nturning interrupts off (combined with the fact that we\u0027re always looking\nup the current mm, means we can do the lockless page table walk within the\nconstraints of the TLB shootdown design).  Basically we can do this\nlockless pagetable walk in a similar manner to the way the CPU\u0027s pagetable\nwalker does not have to take any locks to find present ptes.\n\nThis patch (combined with the subsequent ones to convert direct IO to use\nit) was found to give about 10% performance improvement on a 2 socket 8\ncore Intel Xeon system running an OLTP workload on DB2 v9.5\n\n \"To test the effects of the patch, an OLTP workload was run on an IBM\n  x3850 M2 server with 2 processors (quad-core Intel Xeon processors at\n  2.93 GHz) using IBM DB2 v9.5 running Linux 2.6.24rc7 kernel.  Comparing\n  runs with and without the patch resulted in an overall performance\n  benefit of ~9.8%.  Correspondingly, oprofiles showed that samples from\n  __up_read and __down_read routines that is seen during thread contention\n  for system resources was reduced from 2.8% down to .05%.  Monitoring the\n  /proc/vmstat output from the patched run showed that the counter for\n  fast_gup contained a very high number while the fast_gup_slow value was\n  zero.\"\n\n(fast_gup is the old name for get_user_pages_fast, fast_gup_slow is a\ncounter we had for the number of times the slowpath was invoked).\n\nThe main reason for the improvement is that DB2 has multiple threads each\nissuing direct-IO.  Direct-IO uses get_user_pages, and thus the threads\ncontend the mmap_sem cacheline, and can also contend on page table locks.\n\nI would anticipate larger performance gains on larger systems, however I\nthink DB2 uses an adaptive mix of threads and processes, so it could be\nthat thread contention remains pretty constant as machine size increases.\nIn which case, we stuck with \"only\" a 10% gain.\n\nThe downside of using get_user_pages_fast is that if there is not a pte\nwith the correct permissions for the access, we end up falling back to\nget_user_pages and so the get_user_pages_fast is a bit of extra work.\nHowever this should not be the common case in most performance critical\ncode.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: Kconfig fix]\n[akpm@linux-foundation.org: Makefile fix/cleanup]\n[akpm@linux-foundation.org: warning fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Zach Brown \u003czach.brown@oracle.com\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nReviewed-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "kexec jump: save/restore device state\n\nThis patch implements devices state save/restore before after kexec.\n\nThis patch together with features in kexec_jump patch can be used for\nfollowing:\n\n- A simple hibernation implementation without ACPI support.  You can kexec a\n  hibernating kernel, save the memory image of original system and shutdown\n  the system.  When resuming, you restore the memory image of original system\n  via ordinary kexec load then jump back.\n\n- Kernel/system debug through making system snapshot.  You can make system\n  snapshot, jump back, do some thing and make another system snapshot.\n\n- Cooperative multi-kernel/system.  With kexec jump, you can switch between\n  several kernels/systems quickly without boot process except the first time.\n  This appears like swap a whole kernel/system out/in.\n\n- A general method to call program in physical mode (paging turning\n  off). This can be used to invoke BIOS code under Linux.\n\nThe following user-space tools can be used with kexec jump:\n\n- kexec-tools needs to be patched to support kexec jump. The patches\n  and the precompiled kexec can be download from the following URL:\n       source: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-src_git_kh10.tar.bz2\n       patches: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-patches_git_kh10.tar.bz2\n       binary: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec_git_kh10\n\n- makedumpfile with patches are used as memory image saving tool, it\n  can exclude free pages from original kernel memory image file. The\n  patches and the precompiled makedumpfile can be download from the\n  following URL:\n       source: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-src_cvs_kh10.tar.bz2\n       patches: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-patches_cvs_kh10.tar.bz2\n       binary: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile_cvs_kh10\n\n- An initramfs image can be used as the root file system of kexeced\n  kernel. An initramfs image built with \"BuildRoot\" can be downloaded\n  from the following URL:\n       initramfs image: http://khibernation.sourceforge.net/download/release_v10/initramfs/rootfs_cvs_kh10.gz\n  All user space tools above are included in the initramfs image.\n\nUsage example of simple hibernation:\n\n1. Compile and install patched kernel with following options selected:\n\nCONFIG_X86_32\u003dy\nCONFIG_RELOCATABLE\u003dy\nCONFIG_KEXEC\u003dy\nCONFIG_CRASH_DUMP\u003dy\nCONFIG_PM\u003dy\nCONFIG_HIBERNATION\u003dy\nCONFIG_KEXEC_JUMP\u003dy\n\n2. Build an initramfs image contains kexec-tool and makedumpfile, or\n   download the pre-built initramfs image, called rootfs.gz in\n   following text.\n\n3. Prepare a partition to save memory image of original kernel, called\n   hibernating partition in following text.\n\n4. Boot kernel compiled in step 1 (kernel A).\n\n5. In the kernel A, load kernel compiled in step 1 (kernel B) with\n   /sbin/kexec. The shell command line can be as follow:\n\n   /sbin/kexec --load-preserve-context /boot/bzImage --mem-min\u003d0x100000\n     --mem-max\u003d0xffffff --initrd\u003drootfs.gz\n\n6. Boot the kernel B with following shell command line:\n\n   /sbin/kexec -e\n\n7. The kernel B will boot as normal kexec. In kernel B the memory\n   image of kernel A can be saved into hibernating partition as\n   follow:\n\n   jump_back_entry\u003d`cat /proc/cmdline | tr \u0027 \u0027 \u0027\\n\u0027 | grep kexec_jump_back_entry | cut -d \u0027\u003d\u0027`\n   echo $jump_back_entry \u003e kexec_jump_back_entry\n   cp /proc/vmcore dump.elf\n\n   Then you can shutdown the machine as normal.\n\n8. Boot kernel compiled in step 1 (kernel C). Use the rootfs.gz as\n   root file system.\n\n9. In kernel C, load the memory image of kernel A as follow:\n\n   /sbin/kexec -l --args-none --entry\u003d`cat kexec_jump_back_entry` dump.elf\n\n10. Jump back to the kernel A as follow:\n\n   /sbin/kexec -e\n\n   Then, kernel A is resumed.\n\nImplementation point:\n\nTo support jumping between two kernels, before jumping to (executing)\nthe new kernel and jumping back to the original kernel, the devices\nare put into quiescent state, and the state of devices and CPU is\nsaved. After jumping back from kexeced kernel and jumping to the new\nkernel, the state of devices and CPU are restored accordingly. The\ndevices/CPU state save/restore code of software suspend is called to\nimplement corresponding function.\n\nKnown issues:\n\n- Because the segment number supported by sys_kexec_load is limited,\n  hibernation image with many segments may not be load. This is\n  planned to be eliminated by adding a new flag to sys_kexec_load to\n  make a image can be loaded with multiple sys_kexec_load invoking.\n\nNow, only the i386 architecture is supported.\n\nSigned-off-by: Huang Ying \u003cying.huang@intel.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: \"Eric W.

      "message": "dma-mapping: add the device argument to dma_mapping_error()\n\nAdd per-device dma_mapping_ops support for CONFIG_X86_64 as POWER\narchitecture does:\n\nThis enables us to cleanly fix the Calgary IOMMU issue that some devices\nare not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).\n\nI think that per-device dma_mapping_ops support would be also helpful for\nKVM people to support PCI passthrough but Andi thinks that this makes it\ndifficult to support the PCI passthrough (see the above thread).  So I\nCC\u0027ed this to KVM camp.  Comments are appreciated.\n\nA pointer to dma_mapping_ops to struct dev_archdata is added.  If the\npointer is non NULL, DMA operations in asm/dma-mapping.h use it.  If it\u0027s\nNULL, the system-wide dma_ops pointer is used as before.\n\nIf it\u0027s useful for KVM people, I plan to implement a mechanism to register\na hook called when a new pci (or dma capable) device is created (it works\nwith hot plugging).  It enables IOMMUs to set up an appropriate\ndma_mapping_ops per device.\n\nThe major obstacle is that dma_mapping_error doesn\u0027t take a pointer to the\ndevice unlike other DMA operations.  So x86 can\u0027t have dma_mapping_ops per\ndevice.  Note all the POWER IOMMUs use the same dma_mapping_error function\nso this is not a problem for POWER but x86 IOMMUs use different\ndma_mapping_error functions.\n\nThe first patch adds the device argument to dma_mapping_error.  The patch\nis trivial but large since it touches lots of drivers and dma-mapping.h in\nall the architecture.\n\nThis patch:\n\ndma_mapping_error() doesn\u0027t take a pointer to the device unlike other DMA\noperations.  So we can\u0027t have dma_mapping_ops per device.\n\nNote that POWER already has dma_mapping_ops per device but all the POWER\nIOMMUs use the same dma_mapping_error function.  x86 IOMMUs use device\nargument.\n\n[akpm@linux-foundation.org: fix sge]\n[akpm@linux-foundation.org: fix svc_rdma]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix bnx2x]\n[akpm@linux-foundation.org: fix s2io]\n[akpm@linux-foundation.org: fix pasemi_mac]\n[akpm@linux-foundation.org: fix sdhci]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix sparc]\n[akpm@linux-foundation.org: fix ibmvscsi]\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Muli Ben-Yehuda \u003cmuli@il.ibm.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "edac: i5100 new intel chipset driver\n\nPreliminary support for the Intel 5100 MCH.  CE and UE errors are reported\nalong with the current DIMM label information and other memory parameters.\n\nReasons why this is preliminary:\n\n1) This chip has 2 independent memory controllers which, for best\n   perforance, use interleaved accesses to the DDR2 memory.  This\n   architecture does not map very well to the current edac data structures\n   which depend on symmetric channel access to the interleaved data.\n   Without core changes, the best I could do for now is to map both memory\n   controllers to different csrows (first all ranks of controller 0, then\n   all ranks of controller 1).  Someone much more familiar with the edac\n   core than I will probably need to come up with a more general data\n   structure to handle the interleaving and de-interleaving of the two\n   memory controllers.\n\n2) I have not yet tackled the de-interleaving of the rank/controller\n   address space into the physical address space of the CPU.  There is\n   nothing fundamentally missing, it is just ending up to be a lot of\n   code, and I\u0027d rather keep it separate for now, esp since it doesn\u0027t\n   work yet...\n\n3) The code depends on a particular i5100 chip select to DIMM mainboard\n   chip select mapping.  This mapping seems obvious to me in order to\n   support dual and single ranked memory, but it is not unique and DIMM\n   labels could be wrong on other mainboards.  There is no way to query\n   this mapping that I know of.\n\n4) The code requires that the i5100 is in 32GB mode.  Only 4 ranks per\n   controller, 2 ranks per DIMM are supported.  I do not have hardware\n   (nor do I expect to have hardware anytime soon) for the 48GB (6 ranks\n   per controller) mode.\n\n5) The serial presence detect code should be broken out into a \"real\"\n   i2c driver so that decode-dimms.pl can work.\n\nSigned-off-by: Arthur Jones \u003cajones@riverbed.com\u003e\nSigned-off-by: Doug Thompson \u003cdougthompson@xmission.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "ipc: do not use a negative value to re-enable msgmni automatic recomputing\n\nThis patch proposes an alternative to the \"magical\npositive-versus-negative number trick\" Andrew complained about last week\nin http://lkml.org/lkml/2008/6/24/418.\n\nThis had been introduced with the patches that scale msgmni to the amount\nof lowmem.  With these patches, msgmni has a registered notification\nroutine that recomputes msgmni value upon memory add/remove or ipc\nnamespace creation/ removal.\n\nWhen msgmni is changed from user space (i.e.  value written to the proc\nfile), that notification routine is unregistered, and the way to make it\nregistered back is to write a negative value into the proc file.  This is\nthe \"magical positive-versus-negative number trick\".\n\nTo fix this, a new proc file is introduced: /proc/sys/kernel/auto_msgmni.\nThis file acts as ON/OFF for msgmni automatic recomputing.\n\nWith this patch, the process is the following:\n1) kernel boots in \"automatic recomputing mode\"\n   /proc/sys/kernel/msgmni contains the value that has been computed (depends\n                           on lowmem)\n   /proc/sys/kernel/automatic_msgmni contains \"1\"\n\n2) echo \u003cval\u003e \u003e /proc/sys/kernel/msgmni\n   . sets msg_ctlmni to \u003cval\u003e\n   . de-activates automatic recomputing (i.e. if, say, some memory is added\n     msgmni won\u0027t be recomputed anymore)\n   . /proc/sys/kernel/automatic_msgmni now contains \"0\"\n\n3) echo \"0\" \u003e /proc/sys/kernel/automatic_msgmni\n   . de-activates msgmni automatic recomputing\n     this has the same effect as 2) except that msg_ctlmni\u0027s value stays\n     blocked at its current value)\n\n3) echo \"1\" \u003e /proc/sys/kernel/automatic_msgmni\n   . recomputes msgmni\u0027s value based on the current available memory size\n     and number of ipc namespaces\n   . re-activates automatic recomputing for msgmni.\n\nSigned-off-by: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nCc: Solofo Ramangalahy \u003cSolofo.Ramangalahy@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
