Because old kclist_add() is called per lmb, this\npatch makes no difference in behavior, finally.\n\nAnd this patch removes CONFIG_MEMORY_HOTPLUG check from this function.\nBecause pfn_valid() just show \"there is memmap or not* and cannot be used\nfor \"there is physical memory or not\", this function is useful in generic\nto scan physical memory range.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: WANG Cong \u003cxiyou.wangcong@gmail.com\u003e\nCc: Américo Wang \u003cxiyou.wangcong@gmail.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c30bb2a25fcfde6157e6154a32c14686fb0bedbe", "tree": "afa4811d46e5f9035a035b2c8c864bbb6c5af049", "parents": [ "2ef43ec772551e975a6ea7cf22b59c84955aadf9" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Tue Sep 22 16:45:43 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 23 07:39:41 2009 -0700" }, "message": "kcore: add kclist types\n\nPresently, kclist_add() only eats start address and size as its arguments.\nConsidering to make kclist dynamically reconfigulable, it\u0027s necessary to\nknow which kclists are for System RAM and which are not.\n\nThis patch add kclist types as\n KCORE_RAM\n KCORE_VMALLOC\n KCORE_TEXT\n KCORE_OTHER\n\nThis \"type\" is used in a patch following this for detecting KCORE_RAM.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: WANG Cong \u003cxiyou.wangcong@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2ef43ec772551e975a6ea7cf22b59c84955aadf9", "tree": "9560c13bcc6deb3ee00a60f93730b248029e69bb", "parents": [ "d899bf7b55f503ba7d3d07ed27c3a37e270fa7db" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Tue Sep 22 16:45:41 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 23 07:39:41 2009 -0700" }, "message": "kcore: use usual list for kclist\n\nThis patchset is for /proc/kcore.

That\u0027s because back in those days\nit was popular not to fill in transfer_buffer, so almost all\ntraffic would be invisible (e.g. all of HID was like that).\nBut now, the tree is almost 100% PIO friendly, so we can do the\nright thing at last.\n\nSigned-off-by: Pete Zaitcev \u003czaitcev@redhat.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "f1b0ef062602713c2c7cfa12362d5d90ed01c5f6", "tree": "30a130141b7c4b69ff20d134734acd40f1ee0960", "parents": [ "3ca4f5ca73057a617f9444a91022d7127041970a" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Thu Sep 17 19:57:42 2009 +0200" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Wed Sep 23 22:26:36 2009 +0930" }, "message": "virtio_blk: add support for cache flush\n\nRecent qemu has added a VIRTIO_BLK_F_FLUSH flag to advertise that the\nvirtual disk has a volatile write cache that needs to be flushed.

The\nMAP_HUGETLB flag is a modifier to MAP_ANONYMOUS and will not work without\nboth flags being preset.\n\nA new flag is necessary because there is no other way to hook into huge\npages without creating a file on a hugetlbfs mount which wouldn\u0027t be\nMAP_ANONYMOUS.\n\nTo userspace, this mapping will behave just like an anonymous mapping\nbecause the file is not accessible outside of the kernel.\n\nThis patchset is meant to simplify the programming model. Presently there\nis a large chunk of boiler platecode, contained in libhugetlbfs, required\nto create private, hugepage backed mappings. This patch set would allow\nuse of hugepages without linking to libhugetlbfs or having hugetblfs\nmounted.\n\nUnification of the VM code would provide these same benefits, but it has\nbeen resisted each time that it has been suggested for several reasons: it\nwould break PAGE_SIZE assumptions across the kernel, it makes page-table\nabstractions really expensive, and it does not provide any benefit on\narchitectures that do not support huge pages, incurring fast path\npenalties without providing any benefit on these architectures.\n\nThis patch:\n\nThere are two means of creating mappings backed by huge pages:\n\n 1. mmap() a file created on hugetlbfs\n 2. Use shm which creates a file on an internal mount which essentially\n maps it MAP_SHARED\n\nThe internal mount is only used for shared mappings but there is very\nlittle that stops it being used for private mappings. This patch extends\nhugetlbfs_file_setup() to deal with the creation of files that will be\nmapped MAP_PRIVATE on the internal hugetlbfs mount.

They are based on mmotm-2009-08-27.\n\nPatch 1 adds multiple lists to struct per_cpu_pages, one per\n\tmigratetype that can be stored on the PCP lists.\n\nPatch 2 notes that the pcpu drain path check empty lists multiple times. The\n\tpatch reduces the number of checks by maintaining a count of free\n\tlists encountered. Lists containing pages will then free multiple\n\tpages in batch\n\nThe patches were tested with kernbench, netperf udp/tcp, hackbench and\nsysbench. The netperf tests were not bound to any CPU in particular and\nwere run such that the results should be 99% confidence that the reported\nresults are within 1% of the estimated mean. sysbench was run with a\npostgres background and read-only tests. Similar to netperf, it was run\nmultiple times so that it\u0027s 99% confidence results are within 1%. The\npatches were tested on x86, x86-64 and ppc64 as\n\nx86:\tIntel Pentium D 3GHz with 8G RAM (no-brand machine)\n\tkernbench\t- No significant difference, variance well within noise\n\tnetperf-udp\t- 1.34% to 2.28% gain\n\tnetperf-tcp\t- 0.45% to 1.22% gain\n\thackbench\t- Small variances, very close to noise\n\tsysbench\t- Very small gains\n\nx86-64:\tAMD Phenom 9950 1.3GHz with 8G RAM (no-brand machine)\n\tkernbench\t- No significant difference, variance well within noise\n\tnetperf-udp\t- 1.83% to 10.42% gains\n\tnetperf-tcp\t- No conclusive until buffer \u003e\u003d PAGE_SIZE\n\t\t\t\t4096\t+15.83%\n\t\t\t\t8192\t+ 0.34% (not significant)\n\t\t\t\t16384\t+ 1%\n\thackbench\t- Small gains, very close to noise\n\tsysbench\t- 0.79% to 1.6% gain\n\nppc64:\tPPC970MP 2.5GHz with 10GB RAM (it\u0027s a terrasoft powerstation)\n\tkernbench\t- No significant difference, variance well within noise\n\tnetperf-udp\t- 2-3% gain for almost all buffer sizes tested\n\tnetperf-tcp\t- losses on small buffers, gains on larger buffers\n\t\t\t possibly indicates some bad caching effect.\n\thackbench\t- No significant difference\n\tsysbench\t- 2-4% gain\n\nThis patch:\n\nCurrently the per-cpu page allocator searches the PCP list for pages of\nthe correct migrate-type to reduce the possibility of pages being\ninappropriate placed from a fragmentation perspective. This search is\npotentially expensive in a fast-path and undesirable. Splitting the\nper-cpu list into multiple lists increases the size of a per-cpu structure\nand this was potentially a major problem at the time the search was\nintroduced. These problem has been mitigated as now only the necessary\nnumber of structures is allocated for the running system.\n\nThis patch replaces a list search in the per-cpu allocator with one list\nper migrate type. The potential snag with this approach is when bulk\nfreeing pages. We round-robin free pages based on migrate type which has\nlittle bearing on the cache hotness of the page and potentially checks\nempty lists repeatedly in the event the majority of PCP pages are of one\ntype.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "28b83c5193e7ab951e402252278f2cc79dc4d298", "tree": "10080e8d3957c2a03f8419ab44c9ecb0ffcdaee0", "parents": [ "f168e1b6390e2d79cf57e48e6ae6d9b0a9e2851a" ], "author": { "name": "KOSAKI Motohiro", "email": "kosaki.motohiro@jp.fujitsu.com", "time": "Mon Sep 21 17:03:13 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:39 2009 -0700" }, "message": "oom: move oom_adj value from task_struct to signal_struct\n\nCurrently, OOM logic callflow is here.\n\n __out_of_memory()\n select_bad_process() for each task\n badness() calculate badness of one task\n oom_kill_process() search child\n oom_kill_task() kill target task and mm shared tasks with it\n\nexample, process-A have two thread, thread-A and thread-B and it have very\nfat memory and each thread have following oom_adj and oom_score.\n\n thread-A: oom_adj \u003d OOM_DISABLE, oom_score \u003d 0\n thread-B: oom_adj \u003d 0, oom_score \u003d very-high\n\nThen, select_bad_process() select thread-B, but oom_kill_task() refuse\nkill the task because thread-A have OOM_DISABLE.
