Need to consider sequence is: numaq, srat, amd, dummy.\n and make fall back path working.\n\n2. simply split acpi_numa_init to early_parse_srat.\n a. that early_parse_srat is NOT called for ia64, so you break ia64.\n b. for (i \u003d 0; i \u003c MAX_LOCAL_APIC; i++)\n\t set_apicid_to_node(i, NUMA_NO_NODE)\n still left in numa_init. So it will just clear result from early_parse_srat.\n it should be moved before that....\n c. it breaks ACPI_TABLE_OVERIDE...as the acpi table scan is moved\n early before override from INITRD is settled.\n\n3. that patch TITLE is total misleading, there is NO x86 in the title,\n but it changes critical x86 code. It caused x86 guys did not\n pay attention to find the problem early. Those patches really should\n be routed via tip/x86/mm.\n\n4. after that commit, following range can not use movable ram:\n a. real_mode code.... well..funny, legacy Node0 [0,1M) could be hot-removed?\n b. initrd... it will be freed after booting, so it could be on movable...\n c. crashkernel for kdump...: looks like we can not put kdump kernel above 4G\n\tanymore.\n d. init_mem_mapping: can not put page table high anymore.\n e. initmem_init: vmemmap can not be high local node anymore. That is\n not good.\n\nIf node is hotplugable, the mem related range like page table and\nvmemmap could be on the that node without problem and should be on that\nnode.\n\nWe have workaround patch that could fix some problems, but some can not\nbe fixed.\n\nSo just remove that offending commit and related ones including:\n\n f7210e6c4ac7 (\"mm/memblock.c: use CONFIG_HAVE_MEMBLOCK_NODE_MAP to\n protect movablecore_map in memblock_overlaps_region().\")\n\n 01a178a94e8e (\"acpi, memory-hotplug: support getting hotplug info from\n SRAT\")\n\n 27168d38fa20 (\"acpi, memory-hotplug: extend movablemem_map ranges to\n the end of node\")\n\n e8d195525809 (\"acpi, memory-hotplug: parse SRAT before memblock is\n ready\")\n\n fb06bc8e5f42 (\"page_alloc: bootmem limit with movablecore_map\")\n\n 42f47e27e761 (\"page_alloc: make movablemem_map have higher priority\")\n\n 6981ec31146c (\"page_alloc: introduce zone_movable_limit[] to keep\n movable limit for nodes\")\n\n 34b71f1e04fc (\"page_alloc: add movable_memmap kernel parameter\")\n\n 4d59a75125d5 (\"x86: get pg_data_t\u0027s memory from other node\")\n\nLater we should have patches that will make sure kernel put page table\nand vmemmap on local node ram instead of push them down to node0. Also\nneed to find way to put other kernel used ram to local node ram.\n\nReported-by: Tim Gardner \u003ctim.gardner@canonical.com\u003e\nReported-by: Don Morris \u003cdon.morris@hp.com\u003e\nBisected-by: Don Morris \u003cdon.morris@hp.com\u003e\nTested-by: Don Morris \u003cdon.morris@hp.com\u003e\nSigned-off-by: Yinghai Lu \u003cyinghai@kernel.org\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Thomas Renninger \u003ctrenn@suse.de\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Tang Chen \u003ctangchen@cn.fujitsu.com\u003e\nCc: Yasuaki Ishimatsu \u003cisimatu.yasuaki@jp.fujitsu.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "18a44a7ff1075ce5157ac07cde573aca6b5e9973", "tree": "8b857b12887da983b75bfd0d693df23edb810ba5", "parents": [ "309667e53fcfd8e0b423280b6ea5a648fd92166c", "7c10093692ed2e6f318387d96b829320aa0ca64c" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Feb 27 16:16:39 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Feb 27 16:16:39 2013 -0800" }, "message": "Merge branch \u0027x86-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull more x86 fixes from Peter Anvin:\n \"Additional x86 fixes.

It allows the kernel and all the kernel data objects to be invoked\n from above the 4 GB limit. This allows kdump to work on very large\n systems.\n\n 3. It greatly reduces the difference between Xen and native (Xen\u0027s\n equivalent of the #PF handler are the temporary page tables created\n by the domain builder), eliminating a bunch of fragile hooks.\n\n The patch series also gets us a bit closer to W^X.\n\n Additional work in this pull is the 64-bit get_user() work which you\n were also involved with, and a bunch of cleanups/speedups to\n __phys_addr()/__pa().\"\n\n* \u0027x86-mm-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (105 commits)\n x86, mm: Move reserving low memory later in initialization\n x86, doc: Clarify the use of asm(\"%edx\") in uaccess.h\n x86, mm: Redesign get_user with a __builtin_choose_expr hack\n x86: Be consistent with data size in getuser.S\n x86, mm: Use a bitfield to mask nuisance get_user() warnings\n x86/kvm: Fix compile warning in kvm_register_steal_time()\n x86-32: Add support for 64bit get_user()\n x86-32, mm: Remove reference to alloc_remap()\n x86-32, mm: Remove reference to resume_map_numa_kva()\n x86-32, mm: Rip out x86_32 NUMA remapping code\n x86/numa: Use __pa_nodebug() instead\n x86: Don\u0027t panic if can not alloc buffer for swiotlb\n mm: Add alloc_bootmem_low_pages_nopanic()\n x86, 64bit, mm: hibernate use generic mapping_init\n x86, 64bit, mm: Mark data/bss/brk to nx\n x86: Merge early kernel reserve for 32bit and 64bit\n x86: Add Crash kernel low reservation\n x86, kdump: Remove crashkernel range find limit for 64bit\n memblock: Add memblock_mem_size()\n x86, boot: Not need to check setup_header version for setup_data\n ...\n" }, { "commit": "10baf04e95fbf7eb6089410220a547211dd2ffa7", "tree": "912204612987a3ce2ec0ed214d47911040d79cc1", "parents": [ "fdbe0946d4c35d4cc784cfe0a5322708cfb7ade8", "ca62cf59ceef10ff2ebca0e7f764507186870270" ], "author": { "name": "Rafael J.

In the interest of getting the ball rolling, it would be\n desirable to see this much merged for 3.8 with the view to building\n scheduler smarts on top and adapting the VM where required for 3.9.\n\n The most recent set of comparisons available from different people are\n\n mel: https://lkml.org/lkml/2012/12/9/108\n mingo: https://lkml.org/lkml/2012/12/7/331\n tglx: https://lkml.org/lkml/2012/12/10/437\n srikar: https://lkml.org/lkml/2012/12/10/397\n\n The results are a mixed bag. In my own tests, balancenuma does\n reasonably well. It\u0027s dumb as rocks and does not regress against\n mainline. On the other hand, Ingo\u0027s tests shows that balancenuma is\n incapable of converging for this workloads driven by perf which is bad\n but is potentially explained by the lack of scheduler smarts. Thomas\u0027\n results show balancenuma improves on mainline but falls far short of\n numacore or autonuma. Srikar\u0027s results indicate we all suffer on a\n large machine with imbalanced node sizes.\n\n My own testing showed that recent numacore results have improved\n dramatically, particularly in the last week but not universally.\n We\u0027ve butted heads heavily on system CPU usage and high levels of\n migration even when it shows that overall performance is better.\n There are also cases where it regresses. Of interest is that for\n specjbb in some configurations it will regress for lower numbers of\n warehouses and show gains for higher numbers which is not reported by\n the tool by default and sometimes missed in treports.

Situations requiring\na large number of grace periods to elapse (and wireshark startup has\nbeen called out as an example of this) are helped by lower-latency\ngrace periods. Furthermore, in some embedded applications, people are\nwilling to accept a small degradation in update efficiency (due to there\nbeing more of the shorter grace-period operations) in order to gain the\nlower latency.\n\nIn contrast, those few systems with thousands of CPUs need longer grace\nperiods because the CPU overhead of a grace period rises roughly\nlinearly with the number of CPUs. Such systems normally do not make\nmuch use of facilities that require large numbers of grace periods to\nelapse, so this is a good tradeoff.\n\nTherefore, this commit allows the durations to be controlled from sysfs.\nThere are two sysfs parameters, one named \"jiffies_till_first_fqs\" that\nspecifies the delay in jiffies from the end of grace-period initialization\nuntil the first attempt to force quiescent states, and the other named\n\"jiffies_till_next_fqs\" that specifies the delay (again in jiffies)\nbetween subsequent attempts to force quiescent states. They both default\nto three jiffies, which is compatible with the old hard-coded behavior.\n\nAt some future time, it may be possible to automatically increase the\ngrace-period length with the number of CPUs, but we do not yet have\nsufficient data to do a good job. Preliminary data indicates that we\nshould add an addiitonal jiffy to each of the delays for every 200 CPUs\nin the system, but more experimentation is needed. For now, the number\nof systems with more than 1,000 CPUs is small enough that this can be\nrelegated to boot-time hand tuning.\n\nSigned-off-by: Paul E.

First one is Contiguous Memory\n Allocator (CMA) which makes it possible for device drivers to allocate\n big contiguous chunks of memory after the system has booted.\n\n The main difference from the similar frameworks is the fact that CMA\n allows to transparently reuse the memory region reserved for the big\n chunk allocation as a system memory, so no memory is wasted when no\n big chunk is allocated. Once the alloc request is issued, the\n framework migrates system pages to create space for the required big\n chunk of physically contiguous memory.\n\n For more information one can refer to nice LWN articles:\n\n - \u0027A reworked contiguous memory allocator\u0027:\n\t\thttp://lwn.net/Articles/447405/\n\n - \u0027CMA and ARM\u0027:\n\t\thttp://lwn.net/Articles/450286/\n\n - \u0027A deep dive into CMA\u0027:\n\t\thttp://lwn.net/Articles/486301/\n\n - and the following thread with the patches and links to all previous\n versions:\n\t\thttps://lkml.org/lkml/2012/4/3/204\n\n The main client for this new framework is ARM DMA-mapping subsystem.\n\n The second part provides a complete redesign in ARM DMA-mapping\n subsystem. The core implementation has been changed to use common\n struct dma_map_ops based infrastructure with the recent updates for\n new dma attributes merged in v3.4-rc2. This allows to use more than\n one implementation of dma-mapping calls and change/select them on the\n struct device basis. The first client of this new infractructure is\n dmabounce implementation which has been completely cut out of the\n core, common code.\n\n The last patch of this redesign update introduces a new, experimental\n implementation of dma-mapping calls on top of generic IOMMU framework.\n This lets ARM sub-platform to transparently use IOMMU for DMA-mapping\n calls if one provides required IOMMU hardware.\n\n For more information please refer to the following thread:\n\t\thttp://www.spinics.net/lists/arm-kernel/msg175729.html\n\n The last patch merges changes from both updates and provides a\n resolution for the conflicts which cannot be avoided when patches have\n been applied on the same files (mainly arch/arm/mm/dma-mapping.c).\"\n\nAcked by Andrew Morton \u003cakpm@linux-foundation.org\u003e:\n \"Yup, this one please.

The changes are\n well contained and just plug into the driver new gpu functionality\n so they should be fairly regression proof. I just want to give\n them a bit of a run on the hw AMD kindly sent me.\n\n b) drm prime/dma-buf interface code. This is just infrastructure\n code to expose the dma-buf stuff to drm drivers and to userspace.\n I\u0027m not planning on pushing any driver support in this cycle\n (except maybe exynos), but I\u0027d like to get the infrastructure code\n in so for the next cycle I can start getting the driver support\n into the individual drivers. We have started driver support for\n i915, nouveau and udl along with I think exynos and omap in\n staging. However this code relies on the dma-buf tree being\n pulled into your tree first since it needs the latest interfaces\n from that tree.

The name is passed to the kernel as module parameter of the\ndrm_kms_helper module either when loaded\n options drm_kms_helper edid_firmware\u003dedid/1280x1024.bin\nor as kernel commandline parameter\n drm_kms_helper.edid_firmware\u003dedid/1280x1024.bin\n\nIt is also possible to restrict the usage of a specified EDID data set\nto a particular connector. This is done by prepending the name of the\nconnector to the name of the EDID data set using the syntax\n edid_firmware\u003d[\u003cconnector\u003e:]\u003cedid\u003e\nsuch as, for example,\n edid_firmware\u003dDVI-I-1:edid/1920x1080.bin\nin which case no other connector will be affected.\n\nThe built-in data sets are\nResolution Name\n--------------------------------\n1024x768 edid/1024x768.bin\n1280x1024 edid/1280x1024.bin\n1680x1050 edid/1680x1050.bin\n1920x1080 edid/1920x1080.bin\n\nThey are ignored, if a file with the same name is available in the\n/lib/firmware directory.\n\nThe built-in EDID data sets are based on standard timings that may not\napply to a particular monitor and even crash it. Ideally, EDID data of\nthe connected monitor should be used. They may be obtained through the\ndrm/cardX/cardX-\u003cconnector\u003e/edid entry in the /sys/devices PCI directory\nof a correctly working graphics adapter.\n\nIt is even possible to specify the name of an EDID data set on-the-fly\nvia the /sys/module interface, e.g.\necho edid/myedid.bin \u003e/sys/module/drm_kms_helper/parameters/edid_firmware\nThe new screen mode is considered when the related kernel function is\ncalled for the first time after the change. Such calls are made when the\nX server is started or when the display settings dialog is opened in an\nalready running X server.\n\nSigned-off-by: Carsten Emde \u003cC.Emde@osadl.org\u003e\nSigned-off-by: Dave Airlie \u003cairlied@redhat.com\u003e\n" }, { "commit": "4dca20efb1a9c2efefc28ad2867e5d6c3f5e1955", "tree": "807c4807c91bf53db35fd28e05eaeaa846d41bde", "parents": [ "7bd90909bbf9ce7c40e1da3d72b97b93839c188a" ], "author": { "name": "Carsten Emde", "email": "C.Emde@osadl.org", "time": "Thu Mar 15 15:56:26 2012 +0100" }, "committer": { "name": "Daniel Vetter", "email": "daniel.vetter@ffwll.ch", "time": "Sun Mar 18 21:48:18 2012 +0100" }, "message": "drm/i915: panel: invert brightness via quirk\n\nA machine may need to invert the panel backlight brightness value.
