Next are the\n freezer updates from Colin Cross that should make the freezing of\n tasks a bit less heavy weight.\n\n We also have a couple of regression fixes, a number of fixes for\n issues that have not been identified as regressions, two new drivers\n and a bunch of cleanups all over.\n\n Highlights:\n\n - Hotplug changes to support graceful hot-removal failures.\n\n It sometimes is necessary to fail device hot-removal operations\n gracefully if they cannot be carried out completely. For example,\n if memory from a memory module being hot-removed has been allocated\n for the kernel\u0027s own use and cannot be moved elsewhere, it\u0027s\n desirable to fail the hot-removal operation in a graceful way\n rather than to crash the kernel, but currenty a success or a kernel\n crash are the only possible outcomes of an attempted memory\n hot-removal. Needless to say, that is not a very attractive\n alternative and it had to be addressed.\n\n However, in order to make it work for memory, I first had to make\n it work for CPUs and for this purpose I needed to modify the ACPI\n processor driver. It\u0027s been split into two parts, a resident one\n handling the low-level initialization/cleanup and a modular one\n playing the actual driver\u0027s role (but it binds to the CPU system\n device objects rather than to the ACPI device objects representing\n processors). That\u0027s been sort of like a live brain surgery on a\n patient who\u0027s riding a bike.\n\n So this is a little scary, but since we found and fixed a couple of\n regressions it caused to happen during the early linux-next testing\n (a month ago), nobody has complained.\n\n As a bonus we remove some duplicated ACPI hotplug code, because the\n ACPI-based CPU hotplug is now going to use the common ACPI hotplug\n code.\n\n - Lighter weight freezing of tasks.\n\n These changes from Colin Cross and Mandeep Singh Baines are\n targeted at making the freezing of tasks a bit less heavy weight\n operation. They reduce the number of tasks woken up every time\n during the freezing, by using the observation that the freezer\n simply doesn\u0027t need to wake up some of them and wait for them all\n to call refrigerator(). The time needed for the freezer to decide\n to report a failure is reduced too.\n\n Also reintroduced is the check causing a lockdep warining to\n trigger when try_to_freeze() is called with locks held (which is\n generally unsafe and shouldn\u0027t happen).\n\n - cpufreq updates\n\n First off, a commit from Srivatsa S Bhat fixes a resume regression\n introduced during the 3.10 cycle causing some cpufreq sysfs\n attributes to return wrong values to user space after resume. The\n fix is kind of fresh, but also it\u0027s pretty obvious once Srivatsa\n has identified the root cause.\n\n Second, we have a new freqdomain_cpus sysfs attribute for the\n acpi-cpufreq driver to provide information previously available via\n related_cpus. From Lan Tianyu.\n\n Finally, we fix a number of issues, mostly related to the\n CPUFREQ_POSTCHANGE notifier and cpufreq Kconfig options and clean\n up some code. The majority of changes from Viresh Kumar with bits\n from Jacob Shin, Heiko Stübner, Xiaoguang Chen, Ezequiel Garcia,\n Arnd Bergmann, and Tang Yuantian.\n\n - ACPICA update\n\n A usual bunch of updates from the ACPICA upstream.\n\n During the 3.4 cycle we introduced support for ACPI 5 extended\n sleep registers, but they are only supposed to be used if the\n HW-reduced mode bit is set in the FADT flags and the code attempted\n to use them without checking that bit. That caused suspend/resume\n regressions to happen on some systems. Fix from Lv Zheng causes\n those registers to be used only if the HW-reduced mode bit is set.\n\n Apart from this some other ACPICA bugs are fixed and code cleanups\n are made by Bob Moore, Tomasz Nowicki, Lv Zheng, Chao Guan, and\n Zhang Rui.\n\n - cpuidle updates\n\n New driver for Xilinx Zynq processors is added by Michal Simek.\n\n Multidriver support simplification, addition of some missing\n kerneldoc comments and Kconfig-related fixes come from Daniel\n Lezcano.\n\n - ACPI power management updates\n\n Changes to make suspend/resume work correctly in Xen guests from\n Konrad Rzeszutek Wilk, sparse warning fix from Fengguang Wu and\n cleanups and fixes of the ACPI device power state selection\n routine.\n\n - ACPI documentation updates\n\n Some previously missing pieces of ACPI documentation are added by\n Lv Zheng and Aaron Lu (hopefully, that will help people to\n uderstand how the ACPI subsystem works) and one outdated doc is\n updated by Hanjun Guo.\n\n - Assorted ACPI updates\n\n We finally nailed down the IA-64 issue that was the reason for\n reverting commit 9f29ab11ddbf (\"ACPI / scan: do not match drivers\n against objects having scan handlers\"), so we can fix it and move\n the ACPI scan handler check added to the ACPI video driver back to\n the core.\n\n A mechanism for adding CMOS RTC address space handlers is\n introduced by Lan Tianyu to allow some EC-related breakage to be\n fixed on some systems.\n\n A spec-compliant implementation of acpi_os_get_timer() is added by\n Mika Westerberg.\n\n The evaluation of _STA is added to do_acpi_find_child() to avoid\n situations in which a pointer to a disabled device object is\n returned instead of an enabled one with the same _ADR value. From\n Jeff Wu.\n\n Intel BayTrail PCH (Platform Controller Hub) support is added to\n the ACPI driver for Intel Low-Power Subsystems (LPSS) and that\n driver is modified to work around a couple of known BIOS issues.\n Changes from Mika Westerberg and Heikki Krogerus.\n\n The EC driver is fixed by Vasiliy Kulikov to use get_user() and\n put_user() instead of dereferencing user space pointers blindly.\n\n Code cleanups are made by Bjorn Helgaas, Nicholas Mazzuca and Toshi\n Kani.\n\n - Assorted power management updates\n\n The \"runtime idle\" helper routine is changed to take the return\n values of the callbacks executed by it into account and to call\n rpm_suspend() if they return 0, which allows us to reduce the\n overall code bloat a bit (by dropping some code that\u0027s not\n necessary any more after that modification).\n\n The runtime PM documentation is updated by Alan Stern (to reflect\n the \"runtime idle\" behavior change).\n\n New trace points for PM QoS are added by Sahara\n (\u003ckeun-o.park@windriver.com\u003e).\n\n PM QoS documentation is updated by Lan Tianyu.\n\n Code cleanups are made and minor issues are addressed by Bernie\n Thompson, Bjorn Helgaas, Julius Werner, and Shuah Khan.\n\n - devfreq updates\n\n New driver for the Exynos5-bus device from Abhilash Kesavan.\n\n Minor cleanups, fixes and MAINTAINERS update from MyungJoo Ham,\n Abhilash Kesavan, Paul Bolle, Rajagopal Venkat, and Wei Yongjun.\n\n - OMAP power management updates\n\n Adaptive Voltage Scaling (AVS) SmartReflex voltage control driver\n updates from Andrii Tseglytskyi and Nishanth Menon.\"\n\n* tag \u0027pm+acpi-3.11-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (162 commits)\n cpufreq: Fix cpufreq regression after suspend/resume\n ACPI / PM: Fix possible NULL pointer deref in acpi_pm_device_sleep_state()\n PM / Sleep: Warn about system time after resume with pm_trace\n cpufreq: don\u0027t leave stale policy pointer in cdbs-\u003ecur_policy\n acpi-cpufreq: Add new sysfs attribute freqdomain_cpus\n cpufreq: make sure frequency transitions are serialized\n ACPI: implement acpi_os_get_timer() according the spec\n ACPI / EC: Add HP Folio 13 to ec_dmi_table in order to skip DSDT scan\n ACPI: Add CMOS RTC Operation Region handler support\n ACPI / processor: Drop unused variable from processor_perflib.c\n cpufreq: tegra: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: s3c64xx: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: omap: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: imx6q: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: exynos: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: dbx500: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: davinci: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: arm-big-little: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: powernow-k8: call CPUFREQ_POSTCHANGE notfier in error cases\n cpufreq: pcc: call CPUFREQ_POSTCHANGE notfier in error cases\n ...\n" }, { "commit": "bfd63cd24df69120585c22e09fda78723772ee2a", "tree": "e81b06eb3b5f9b4270d995bdf15758e9895cd62b", "parents": [ "6a2c123427ffece4174db0792c3009e7df770d9a" ], "author": { "name": "Michael Opdenacker", "email": "michael.opdenacker@free-electrons.com", "time": "Wed Jun 26 05:57:06 2013 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Tue Jun 25 21:20:41 2013 -0700" }, "message": "driver core: device.h: fix doc compilation warnings\n\nThis patch fixes the below 3 warnings running \"make htmldocs\",\nby adding descriptions for recently added structure members:\n\nDOCPROC Documentation/DocBook/device-drivers.xml\nWarning(/work/git.free-electrons.com/users/michael-opdenacker/linux//include/linux/device.h:116): No description found for parameter \u0027lock_key\u0027\nWarning(/work/git.free-electrons.com/users/michael-opdenacker/linux//include/linux/device.h:723): No description found for parameter \u0027cma_area\u0027\nWarning(/work/git.free-electrons.com/users/michael-opdenacker/linux//include/linux/device.h:723): No description found for parameter \u0027iommu_group\u0027\n\nDon\u0027t hesitate to propose better descriptions!\n\nSigned-off-by: Michael Opdenacker \u003cmichael.opdenacker@free-electrons.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "4f3549d72d1b5c90ecc7e673402f38f4486d22c2", "tree": "bec88e98010e129f4105cab3ff0e490166e1cbe3", "parents": [ "dd3652ed1a5328a91352409fe81af3e7d629e44b" ], "author": { "name": "Rafael J.

Unfortunately, however, the\nkernel currently doesn\u0027t provide any support for that.\n\nTo address that deficiency, introduce support for offline and\nonline operations that can be performed on devices, respectively,\nbefore a hot-removal and in case when it is necessary (or convenient)\nto put a device back online after a successful offline (that has not\nbeen followed by removal). The idea is that the offline will fail\nwhenever the given device cannot be gracefully removed from the\nsystem and it will not be allowed to use the device after a\nsuccessful offline (until a subsequent online) in analogy with the\nexisting CPU offline/online mechanism.\n\nFor now, the offline and online operations are introduced at the\nbus type level, as that should be sufficient for the most urgent use\ncases (CPUs and memory modules). In the future, however, the\napproach may be extended to cover some more complicated device\noffline/online scenarios involving device drivers etc.\n\nThe lock_device_hotplug() and unlock_device_hotplug() functions are\nintroduced because subsequent patches need to put larger pieces of\ncode under device_hotplug_lock to prevent race conditions between\ndevice offline and removal from happening.\n\nSigned-off-by: Rafael J.

The changes achieve\n the followings.\n\n - WQ_UNBOUND workqueues - the workqueues which are per-cpu - are\n updated to be able to interface with multiple backend worker pools.\n This involved a lot of churning but the end result seems actually\n neater as unbound workqueues are now a lot closer to per-cpu ones.\n\n - The ability to interface with multiple backend worker pools are\n used to implement unbound workqueues with custom attributes.\n Currently the supported attributes are the nice level and CPU\n affinity. It may be expanded to include cgroup association in\n future. The attributes can be specified either by calling\n apply_workqueue_attrs() or through /sys/bus/workqueue/WQ_NAME/* if\n the workqueue in question is exported through sysfs.\n\n The backend worker pools are keyed by the actual attributes and\n shared by any workqueues which share the same attributes. When\n attributes of a workqueue are changed, the workqueue binds to the\n worker pool with the specified attributes while leaving the work\n items which are already executing in its previous worker pools\n alone.\n\n This allows converting custom worker pool implementations which\n want worker attribute tuning to use workqueues. The writeback pool\n is already converted in block tree and there are a couple others\n are likely to follow including btrfs io workers.\n\n - WQ_UNBOUND\u0027s ability to bind to multiple worker pools is also used\n to make it NUMA-aware. Because there\u0027s no association between work\n item issuer and the specific worker assigned to execute it, before\n this change, using unbound workqueue led to unnecessary cross-node\n bouncing and it couldn\u0027t be helped by autonuma as it requires tasks\n to have implicit node affinity and workers are assigned randomly.\n\n After these changes, an unbound workqueue now binds to multiple\n NUMA-affine worker pools so that queued work items are executed in\n the same node. This is turned on by default but can be disabled\n system-wide or for individual workqueues.\n\n Crypto was requesting NUMA affinity as encrypting data across\n different nodes can contribute noticeable overhead and doing it\n per-cpu was too limiting for certain cases and IO throughput could\n be bottlenecked by one CPU being fully occupied while others have\n idle cycles.\n\n While the new features required a lot of changes including\n restructuring locking, it didn\u0027t complicate the execution paths much.\n The unbound workqueue handling is now closer to per-cpu ones and the\n new features are implemented by simply associating a workqueue with\n different sets of backend worker pools without changing queue,\n execution or flush paths.\n\n As such, even though the amount of change is very high, I feel\n relatively safe in that it isn\u0027t likely to cause subtle issues with\n basic correctness of work item execution and handling. If something\n is wrong, it\u0027s likely to show up as being associated with worker pools\n with the wrong attributes or OOPS while workqueue attributes are being\n changed or during CPU hotplug.\n\n While this creates more backend worker pools, it doesn\u0027t add too many\n more workers unless, of course, there are many workqueues with unique\n combinations of attributes. Assuming everything else is the same,\n NUMA awareness costs an extra worker pool per NUMA node with online\n CPUs.\n\n There are also a couple things which are being routed outside the\n workqueue tree.\n\n - block tree pulled in workqueue for-3.10 so that writeback worker\n pool can be converted to unbound workqueue with sysfs control\n exposed. This simplifies the code, makes writeback workers\n NUMA-aware and allows tuning nice level and CPU affinity via sysfs.\n\n - The conversion to workqueue means that there\u0027s no 1:1 association\n between a specific worker, which makes writeback folks unhappy as\n they want to be able to tell which filesystem caused a problem from\n backtrace on systems with many filesystems mounted. This is\n resolved by allowing work items to set debug info string which is\n printed when the task is dumped.

To\nthis end, it is sufficient to add a pointer to an array of supported\nACPI device IDs, that can be provided by the driver, to struct device.\n\nMoreover, things like ACPI power management need to have access to\nthe ACPI handle of each supported device, because that handle is used\nto invoke AML methods associated with the corresponding ACPI device\nnode. The ACPI handles of devices are now stored in the archdata\nmember structure of struct device whose definition depends on the\narchitecture and includes the ACPI handle only on x86 and ia64. Since\nthe pointer to an array of supported ACPI IDs is added to struct\ndevice_driver in an architecture-independent way, it is logical to\nmove the ACPI handle from archdata to struct device itself at the same\ntime.

Which in turn meant that\n\"wait_for_device_probe()\" would not wait for the SCSI partitions to be\nparsed.\n\nAnd \"wait_for_device_probe()\" was what the boot time init code relied on\nfor mounting the root filesystem.\n\nNow, most people never noticed this, because not only is it\ntiming-dependent, but modern distributions all use initrd. So the root\nfilesystem isn\u0027t actually on a disk at all. And then before they\nactually mount the final disk filesystem, they will have loaded the\nscsi-wait-scan module, which not only does the expected\nwait_for_device_probe(), but also does scsi_complete_async_scans().\n\n[ Side note: scsi_complete_async_scans() had also been partially broken,\n but that was fixed in commit 43a8d39d0137 (\"fix async probe\n regression\"), so that same commit a7a20d103994 had actually broken\n setups even if you used scsi-wait-scan explicitly ]\n\nSolve this problem by just moving the scsi_complete_async_scans() call\ninto wait_for_device_probe(). Everybody who wants to wait for device\nprobing to finish really wants the SCSI probing to complete, so there\u0027s\nno reason not to do this.\n\nSo now \"wait_for_device_probe()\" really does what the name implies, and\nproperly waits for device probing to finish.

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\nproblem arises because lockdep is unable to deal with the\ntree-structured locks created by the device core and sysfs.\n\nThis particular problem involves a sysfs attribute method that\nunregisters itself, not from the device it was called for, but from a\ndescendant device. Lockdep doesn\u0027t understand the distinction and\nreports a possible deadlock, even though the operation is safe.\n\nThis is the sort of thing that would normally be handled by using a\nnested lock annotation; unfortunately it\u0027s not feasible to do that\nhere. There\u0027s no sensible way to tell sysfs when attribute removal\noccurs in the context of a parent attribute method.\n\nAs a workaround, the patch adds a new flag to struct attribute\ntelling sysfs not to inform lockdep when it acquires a readlock on a\nsysfs_dirent instance for the attribute. The readlock is still\nacquired, but lockdep doesn\u0027t know about it and hence does not\ncomplain about impossible deadlock scenarios.\n\nAlso added are macros for static initialization of attribute\nstructures with the ignore_lockdep flag set.

It is going to be a\n bit more nasty than usual as in touching things outside of\n arch/powerpc mostly due to the big iSeriesectomy :-) We finally got\n rid of the bugger (legacy iSeries support) which was a PITA to\n maintain and that nobody really used anymore.\n\n Here are some of the highlights:\n\n - Legacy iSeries is gone. Thanks Stephen ! There\u0027s still some bits\n and pieces remaining if you do a grep -ir series arch/powerpc but\n they are harmless and will be removed in the next few weeks\n hopefully.\n\n - The \u0027fadump\u0027 functionality (Firmware Assisted Dump) replaces the\n previous (equivalent) \"pHyp assisted dump\"... it\u0027s a rewrite of a\n mechanism to get the hypervisor to do crash dumps on pSeries, the\n new implementation hopefully being much more reliable. Thanks\n Mahesh Salgaonkar.\n\n - The \"EEH\" code (pSeries PCI error handling \u0026 recovery) got a big\n spring cleaning, motivated by the need to be able to implement a\n new backend for it on top of some new different type of firwmare.\n\n The work isn\u0027t complete yet, but a good chunk of the cleanups is\n there.

In those cases the same \"platform\" device driver\nmay be used with multiple different system configurations, but the\nactions needed to put the devices it handles into a low-power state\nand back into the full-power state may depend on the design of the\ngiven SoC. The driver, however, cannot possibly include all the\ninformation necessary for the power management of its device on all\nthe systems it is used with. Moreover, the device hierarchy in its\ncurrent form also is not suitable for representing this kind of\ninformation.\n\nThe patch below attempts to address this problem by introducing\nobjects of type struct dev_power_domain that can be used for\nrepresenting power domains within a SoC. Every struct\ndev_power_domain object provides a sets of device power\nmanagement callbacks that can be used to perform what\u0027s needed for\ndevice power management in addition to the operations carried out by\nthe device\u0027s driver and subsystem.\n\nNamely, if a struct dev_power_domain object is pointed to by the\npwr_domain field in a struct device, the callbacks provided by its\nops member will be executed in addition to the corresponding\ncallbacks provided by the device\u0027s subsystem and driver during all\npower transitions.\n\nSigned-off-by: Rafael J.

This is the same that\nwas done back in October 2006 by Russell King for\ndevice_for_each_child(), for exactly the same reasons.\n\nSigned-off-by: Jean Delvare \u003ckhali@linux-fr.org\u003e\nCc: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "99bcf217183e02ebae46373896fba7f12d588001", "tree": "03210a8c57e33b2b5073f80f9a7f818c84f4c83a", "parents": [ "7db6f5fb65a82af03229eef104dc9899c5eecf33" ], "author": { "name": "Joe Perches", "email": "joe@perches.com", "time": "Sun Jun 27 01:02:34 2010 +0000" }, "committer": { "name": "David S.
