IOMMU Updates for Linux v3.10
The updates are mostly about the x86 IOMMUs this time. Exceptions are the groundwork for the PAMU IOMMU from Freescale (for a PPC platform) and an extension to the IOMMU group interface. On the x86 side this includes a workaround for VT-d to disable interrupt remapping on broken chipsets. On the AMD-Vi side the most important new feature is a kernel command-line interface to override broken information in IVRS ACPI tables and get interrupt remapping working this way. Besides that there are small fixes all over the place. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJRh2vAAAoJECvwRC2XARrjbjkP/jzKzeffybUpQsIJF8rs/IEt hSwqpGLr6WR5FdneEH9fiBIp4pyMDXmuAb/2ZNgB+DgPN3xgqmWVo4WLk7pMo3BS /xIz/lu7hIX3AtKt807pL9+rPdhGYEJ43Vmr4bW9x0l1kuNXy6fmMLcN5FaPKjV4 p4hY4jOstEgtYQw4wi39/9b4FsYoipZizkOUSdtCzWwTv7jOHH7/Wra8iZyzL6Je 1VlF/efp0ytTcwLdHOfGwPCIlZrQRtQCM4SqdAUG9bOL3ARR9Yu/0iW1295nbLzo CQX5CfKePvo/fGxki1jcBi+UCyxYKPosB5kCxmh4MAxCg/VzzMsaME/A73tLJa6W Y29bbjwPoBPMq03HX8S9R5QWY8HpFujUUp+J4TXcKuTgYEV28WfLu1uaeKD716nM LoXUojov7Cj8ZQZnhyu5l+XNaephBZLfw/8bM6bAxhlKXwAjmLiS5Z+srPl1GJee 5GCV+L94JifHLZaREWh3JFsh9O3W7Wno2++c4JU32uCWJHXH7tMgs2P8n5AY9rnT Km1a9y6w2MF3Gg9j4y6u75m0XnFTNzYjeJMUtqVlwVhNHhgaXfuIWY63xOQCLJs1 ThTHOjoh0VqONGobR/ywn+0ouo9X07DnWpluyFd+zY3XK0UE0NOu9XMr4i6TWxOf mlzWoEKxtw36XGHB/FtQ =MVc/ -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "The updates are mostly about the x86 IOMMUs this time.

For 3.10 we have a few new MFD drivers for:
- The ChromeOS embedded controller which provides keyboard, battery and power management services. This controller is accessible through i2c or SPI. - Silicon Laboratories 476x controller, providing access to their FM chipset and their audio codec. - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader. - Nokia's Tahvo power button and watchdog device. This device is very similar to Retu and is thus supported by the same code base. - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by the stmpe driver. - ST-Ericsson AB8540 and AB8505 power management and voltage converter controllers through the existing ab8500 code. Some other drivers got cleaned up or improved. In particular: - The Linaro/STE guys got the ab8500 driver in sync with their internal code through a series of optimizations, fixes and improvements. - The AS3711 and OMAP USB drivers now have DT support. - The arizona clock and interrupt handling code got improved. - The wm5102 register patch and boot mechanism also got improved. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJRhttxAAoJEIqAPN1PVmxKl6QP/ilyz2OnuZSJKAT+N3tt0EpR 6hFk0H6uSiHJ5aNyA22WGJq97R3jW9eGK9uD4AKCQ05l9UF/c5+YeXtmGHtxDLCb jBrErfB6GmEn1H2TzVK+Rp1WPAB/yoYHJosgGNCwohvuffhMiogSVHlI09EY4mQh 2Eo0RTN1UXKXSOZN+E7hb+GbIFzU8eOlEFdc2jh4qtfsvMDANbEByrZM6s0QFB31 LPn03uBL0+iwE8KW2144LKsfzeOos4JWbumyG9Lh6BugUSy1e/Zvv7aWNVeMvY8C 0+ZUk0bzRm9g7e3X4iYLPSboZt7J6DLaBlWXnUaOsJb+YRkUGh094ySdKojP3EiK 8SWSfH4EDwIANKC4zyXMcyny8OewySyrTTd0BTlbgHFyDmvmHk213crsCcilHzRb 3wrX0ETrk96Dkla4/e7IAyME+AbrglStHVGGf2hexlPm2nZdLsE8lfyo9yqjPqzy w49y7mpTA5PVE63szB1tI/58W2snZtXAEdQGjZmDQp29vDZaeR1t3W/IhKNG30JN SZGiX3H/6YS4MDZ48N709H83hM4V93XrHKsN59NjQe8NZ7AnSIfns9IgMciGBv7r aBE+Uwm9htK270Hvl5q8qDDnKaVGYOFlCq9qaeZ2k8NPyyRlQCRpJYjtSplYAnGr iLI0JdM32u3qdf5IT+Cw =Wq20 -----END PGP SIGNATURE----- Merge tag 'mfd-3.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next Pull MFD update from Samuel Ortiz: "For 3.10 we have a few new MFD drivers for: - The ChromeOS embedded controller which provides keyboard, battery and power management services.

Merge branch 'timers-nohz-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull 'full dynticks' support from Ingo Molnar: "This tree from Frederic Weisbecker adds a new, (exciting! :-) core kernel feature to the timer and scheduler subsystems: 'full dynticks', or CONFIG_NO_HZ_FULL=y. This feature extends the nohz variable-size timer tick feature from idle to busy CPUs (running at most one task) as well, potentially reducing the number of timer interrupts significantly. This feature got motivated by real-time folks and the -rt tree, but the general utility and motivation of full-dynticks runs wider than that: - HPC workloads get faster: CPUs running a single task should be able to utilize a maximum amount of CPU power. A periodic timer tick at HZ=1000 can cause a constant overhead of up to 1.0%. This feature removes that overhead - and speeds up the system by 0.5%-1.0% on typical distro configs even on modern systems. - Real-time workload latency reduction: CPUs running critical tasks should experience as little jitter as possible. The last remaining source of kernel-related jitter was the periodic timer tick. - A single task executing on a CPU is a pretty common situation, especially with an increasing number of cores/CPUs, so this feature helps desktop and mobile workloads as well. The cost of the feature is mainly related to increased timer reprogramming overhead when a CPU switches its tick period, and thus slightly longer to-idle and from-idle latency. Configuration-wise a third mode of operation is added to the existing two NOHZ kconfig modes: - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named as a config option. This is the traditional Linux periodic tick design: there's a HZ tick going on all the time, regardless of whether a CPU is idle or not. - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ=y], this turns off the periodic tick when a CPU enters idle mode. - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the tick when a CPU is idle, also slows the tick down to 1 Hz (one timer interrupt per second) when only a single task is running on a CPU. The .config behavior is compatible: existing !CONFIG_NO_HZ and CONFIG_NO_HZ=y settings get translated to the new values, without the user having to configure anything. CONFIG_NO_HZ_FULL is turned off by default. This feature is based on a lot of infrastructure work that has been steadily going upstream in the last 2-3 cycles: related RCU support and non-periodic cputime support in particular is upstream already. This tree adds the final pieces and activates the feature. The pull request is marked RFC because: - it's marked 64-bit only at the moment - the 32-bit support patch is small but did not get ready in time. - it has a number of fresh commits that came in after the merge window. The overwhelming majority of commits are from before the merge window, but still some aspects of the tree are fresh and so I marked it RFC. - it's a pretty wide-reaching feature with lots of effects - and while the components have been in testing for some time, the full combination is still not very widely used. That it's default-off should reduce its regression abilities and obviously there are no known regressions with CONFIG_NO_HZ_FULL=y enabled either. - the feature is not completely idempotent: there is no 100% equivalent replacement for a periodic scheduler/timer tick. In particular there's ongoing work to map out and reduce its effects on scheduler load-balancing and statistics. This should not impact correctness though, there are no known regressions related to this feature at this point. - it's a pretty ambitious feature that with time will likely be enabled by most Linux distros, and we'd like you to make input on its design/implementation, if you dislike some aspect we missed. Without flaming us to crisp! :-) Future plans: - there's ongoing work to reduce 1Hz to 0Hz, to essentially shut off the periodic tick altogether when there's a single busy task on a CPU. We'd first like 1 Hz to be exposed more widely before we go for the 0 Hz target though. - once we reach 0 Hz we can remove the periodic tick assumption from nr_running>=2 as well, by essentially interrupting busy tasks only as frequently as the sched_latency constraints require us to do - once every 4-40 msecs, depending on nr_running. I am personally leaning towards biting the bullet and doing this in v3.10, like the -rt tree this effort has been going on for too long - but the final word is up to you as usual.

ARM: arm-soc driver changes for 3.10
This is a rather large set of patches for device drivers that for one reason or another the subsystem maintainer preferred to get merged through the arm-soc tree. There are both new drivers as well as existing drivers that are getting converted from platform-specific code into standalone drivers using the appropriate subsystem specific interfaces. In particular, we can now have pinctrl, clk, clksource and irqchip drivers in one file per driver, without the need to call into platform specific interface, or to get called from platform specific code, as long as all information about the hardware is provided through a device tree. Most of the drivers we touch this time are for clocksource. Since now most of them are part of drivers/clocksource, I expect that we won't have to touch these again from arm-soc and can let the clocksource maintainers take care of these in the future. Another larger part of this series is specific to the exynos platform, which is seeing some significant effort in upstreaming and modernization of its device drivers this time around, which unfortunately is also the cause for the churn and a lot of the merge conflicts. There is one new subsystem that gets merged as part of this series: the reset controller interface, which is a very simple interface for taking devices on the SoC out of reset or back into reset. Patches to use this interface on i.MX follow later in this merge window, and we are going to have other platforms (at least tegra and sirf) get converted in 3.11. This will let us get rid of platform specific callbacks in a number of platform independent device drivers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJRhKUsAAoJEIwa5zzehBx3Ug4P/RqEen15hxS/NY8SIVRAU5c0 G9ZiSPcLmvXGR/t1RZFeLWKaKOYRb2oW1EbXrlkddprkmg85RuQE/KMpCgzPPhVC Yrs8UaagMGblaLOjwavVjin/CUXZokRdMfsQoIyMGOezmVGFnv4d4Kt64IOf35DF 24vDv/QO0BAI9k6m6WLqlWvSshb0IkW8r2LneRLnMEAVop7b1xkOxz0sR6l0LWfV 6JAMXyTjJMg0t8uCVW/QyNdxcxINHhV4SYcNkzF3EZ7ol50OiJsT9fg0XW759+Wb vlX6Xuehg+CBOg+g3ZOZuR8JOEkOhAGRSzuJkk/TmLCCxc+ghnuYz8HArxh6GMHK KaxvogLIi0ZsD94A/BZIKkDtOLWlzdz2HBrYo9PTz8zrOz/gXhwQ3zq0jPccC5E0 S+YYiobCBXepknF9301ti7wGD9VDzI8nmqOKG6tEBrD3xuO+RoBv+z4pBugN4/1C DlB19gOz60G5kniziL+wlmWER2qXmYrQZqS+s6+B2XoyoETC0Yij3Rck5vyC6qIK A2sni+Y9rzNOB9nzmnISP/UiGUffCy8AV4DZJjMSl0XkF4cpOXqRVGZ2nGB4tR5q GTOETcDCo5dvMDKX7Wfrz40CQzO39tnPCddg3OIS93ZwMpCeykIlb1FVL7RcsyF7 3uikzYHlDo3C5pvtJ5TS =ZWk9 -----END PGP SIGNATURE----- Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver changes from Olof Johansson: "This is a rather large set of patches for device drivers that for one reason or another the subsystem maintainer preferred to get merged through the arm-soc tree.

hwmon: (lm75) Tune resolution and sample time per chip
Most LM75-compatible chips can either sample much faster or with a much better resolution than the original LM75 chip. So far the lm75 driver did not let the user take benefit of these improvements. Do it now. I decided to almost always configure the chip to use the best resolution possible, which also means the longest sample time. The only chips for which I didn't are the DS75, DS1775 and STDS75, because they are really too slow in 12-bit mode (1.2 to 1.5 second worst case) so I went for 11-bit mode as a more reasonable tradeoff. This choice is dictated by the fact that the hwmon subsystem is meant for system monitoring, it has never been supposed to be ultra-fast, and as a matter of fact we do cache the sampled values in almost all drivers. If anyone isn't pleased with these default settings, they can always introduce a platform data structure or DT support for the lm75. That being said, it seems nobody ever complained that the driver wouldn't refresh the value faster than every 1.5 second, and the change made it faster for all chips even in 12-bit mode, so I don't expect any complaint.

Pull i2c changes from Wolfram Sang: - an arbitration driver. While the driver is quite simple, it caused discussion if we need additional arbitration on top of the one specified in the I2C standard. Conclusion is that I accept a few generic mechanisms, but not very specific ones. - the core lost the detach_adapter() call. It has no users anymore and was in the way for other cleanups. attach_adapter() is sadly still there since there are users waiting to be converted. - the core gained a bus recovery infrastructure. I2C defines a way to recover if the data line is stalled. This mechanism is now in the core and drivers can now pass some data to make use of it. - bigger driver cleanups for designware, s3c2410 - removing superfluous refcounting from drivers - removing Ben Dooks as second maintainer due to inactivity.

KVM: PPC: Book3S: Add API for in-kernel XICS emulation
This adds the API for userspace to instantiate an XICS device in a VM and connect VCPUs to it. The API consists of a new device type for the KVM_CREATE_DEVICE ioctl, a new capability KVM_CAP_IRQ_XICS, which functions similarly to KVM_CAP_IRQ_MPIC, and the KVM_IRQ_LINE ioctl, which is used to assert and deassert interrupt inputs of the XICS. The XICS device has one attribute group, KVM_DEV_XICS_GRP_SOURCES. Each attribute within this group corresponds to the state of one interrupt source. The attribute number is the same as the interrupt source number. This does not support irq routing or irqfd yet.

rbd: don't create sysfs entries for non-mapped snapshots
When an rbd image gets mapped a device entry gets created for it under /sys/bus/rbd/devices/<id>/. Inside that directory there are sysfs files that contain information about the image: its size, feature bits, major device number, and so on. Additionally, if that image has any snapshots, a device entry gets created for each of those as a "child" of the mapped device. Each of these is a subdirectory of the mapped device, and each directory contains a few files with information about the snapshot (its snapshot id, size, and feature mask). There is no clear benefit to having those device entries for the snapshots. The information provided via sysfs of of little real value--and all of it is available via rbd CLI commands. If we still wanted to see the kernel's view of this information it could be done much more simply by including it in a single sysfs file for the mapped image. But there *is* a clear cost to supporting them. Every time a snapshot context changes, these entries need to be updated (deleted snapshots removed, new snapshots created). The rbd driver is notified of changes to the snapshot context via callbacks from an osd, and care must be taken to coordinate removal of snapshot data structures with the possibility of one these notifications occurring. Things would be considerably simpler if we just didn't have to maintain device entries for the snapshots. So get rid of them. The ability to map a snapshot of an rbd image will remain; the only thing lost will be the ability to query these sysfs directories for information about snapshots of mapped images.

dma-buf: replace dma_buf_export() with dma_buf_export_named()
For debugging purposes, it is useful to have a name-string added while exporting buffers. Hence, dma_buf_export() is replaced with dma_buf_export_named(), which additionally takes 'exp_name' as a parameter. For backward compatibility, and for lazy exporters who don't wish to name themselves, a #define dma_buf_export() is also made available, which adds a __FILE__ instead of 'exp_name'.

This inconsistent help message will also lead more confused when 26 upper-case letters put into use in future. This patch fix sysrq documentation.

With these patches chargers and batteries can now lookup each other without the board files support shim. Rhyland Klein at NVIDIA did the work; - New ST-Ericsson ABX500 hwmon driver.

It has an appropriate ack from the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored the driver; - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes touch mfd parts, but these were acked by the appropriate MFD maintainer (i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead the submission process.

Pull fixup for trivial branch from Jiri Kosina: "Unfortunately I made a mistake when merging into for-linus branch, and omitted one pre-requisity patch for a few other patches (which have been Acked by the appropriate maintainers) in the series. Mea culpa maxima, sorry for that." The trivial branch added %pSR usage before actually teaching vsnprintf() about the 'R' part of %pSR. The 'R' causes the symbol translation to do a "__builtin_extract_return_addr()" before symbol lookup. That said, on most architectures __builtin_extract_return_addr() isn't likely to do anything special, so it probably is not normally noticeable. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial: vsprintf: Add extension %pSR - print_symbol replacement |

vsprintf: Add extension %pSR - print_symbol replacement
print_symbol takes a long and converts it to a function name and offset. %pS does something similar, but doesn't translate the address via __builtin_extract_return_addr. %pSR does the translation. This will enable replacing multiple calls like printk(...); printk_symbol(addr); printk("\n"); with a single non-interleavable in dmesg printk("... %pSR\n", (void *)addr); Update documentation too.

Pull cgroup updates from Tejun Heo: - Fixes and a lot of cleanups. Locking cleanup is finally complete. cgroup_mutex is no longer exposed to individual controlelrs which used to cause nasty deadlock issues. Li fixed and cleaned up quite a bit including long standing ones like racy cgroup_path(). - device cgroup now supports proper hierarchy thanks to Aristeu. - perf_event cgroup now supports proper hierarchy. - A new mount option "__DEVEL__sane_behavior" is added. As indicated by the name, this option is to be used for development only at this point and generates a warning message when used. Unfortunately, cgroup interface currently has too many brekages and inconsistencies to implement a consistent and unified hierarchy on top. The new flag is used to collect the behavior changes which are necessary to implement consistent unified hierarchy. It's likely that this flag won't be used verbatim when it becomes ready but will be enabled implicitly along with unified hierarchy. The option currently disables some of broken behaviors in cgroup core and also .use_hierarchy switch in memcg (will be routed through -mm), which can be used to make very unusual hierarchy where nesting is partially honored. It will also be used to implement hierarchy support for blk-throttle which would be impossible otherwise without introducing a full separate set of control knobs. This is essentially versioning of interface which isn't very nice but at this point I can't see any other options which would allow keeping the interface the same while moving towards hierarchy behavior which is at least somewhat sane. The planned unified hierarchy is likely to require some level of adaptation from userland anyway, so I think it'd be best to take the chance and update the interface such that it's supportable in the long term. Maintaining the existing interface does complicate cgroup core but shouldn't put too much strain on individual controllers and I think it'd be manageable for the foreseeable future. Maybe we'll be able to drop it in a decade. Fix up conflicts (including a semantic one adding a new #include to ppc that was uncovered by header the file changes) as per Tejun. * 'for-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: (45 commits) cpuset: fix compile warning when CONFIG_SMP=n cpuset: fix cpu hotplug vs rebuild_sched_domains() race cpuset: use rebuild_sched_domains() in cpuset_hotplug_workfn() cgroup: restore the call to eventfd->poll() cgroup: fix use-after-free when umounting cgroupfs cgroup: fix broken file xattrs devcg: remove parent_cgroup. memcg: force use_hierarchy if sane_behavior cgroup: remove cgrp->top_cgroup cgroup: introduce sane_behavior mount option move cgroupfs_root to include/linux/cgroup.h cgroup: convert cgroupfs_root flag bits to masks and add CGRP_ prefix cgroup: make cgroup_path() not print double slashes Revert "cgroup: remove bind() method from cgroup_subsys." perf: make perf_event cgroup hierarchical cgroup: implement cgroup_is_descendant() cgroup: make sure parent won't be destroyed before its children cgroup: remove bind() method from cgroup_subsys. devcg: remove broken_hierarchy tag cgroup: remove cgroup_lock_is_held() ... |

Pull workqueue updates from Tejun Heo: "A lot of activities on workqueue side this time. The changes achieve the followings. - WQ_UNBOUND workqueues - the workqueues which are per-cpu - are updated to be able to interface with multiple backend worker pools. This involved a lot of churning but the end result seems actually neater as unbound workqueues are now a lot closer to per-cpu ones. - The ability to interface with multiple backend worker pools are used to implement unbound workqueues with custom attributes. Currently the supported attributes are the nice level and CPU affinity. It may be expanded to include cgroup association in future. The attributes can be specified either by calling apply_workqueue_attrs() or through /sys/bus/workqueue/WQ_NAME/* if the workqueue in question is exported through sysfs. The backend worker pools are keyed by the actual attributes and shared by any workqueues which share the same attributes. When attributes of a workqueue are changed, the workqueue binds to the worker pool with the specified attributes while leaving the work items which are already executing in its previous worker pools alone. This allows converting custom worker pool implementations which want worker attribute tuning to use workqueues. The writeback pool is already converted in block tree and there are a couple others are likely to follow including btrfs io workers. - WQ_UNBOUND's ability to bind to multiple worker pools is also used to make it NUMA-aware. Because there's no association between work item issuer and the specific worker assigned to execute it, before this change, using unbound workqueue led to unnecessary cross-node bouncing and it couldn't be helped by autonuma as it requires tasks to have implicit node affinity and workers are assigned randomly. After these changes, an unbound workqueue now binds to multiple NUMA-affine worker pools so that queued work items are executed in the same node. This is turned on by default but can be disabled system-wide or for individual workqueues. Crypto was requesting NUMA affinity as encrypting data across different nodes can contribute noticeable overhead and doing it per-cpu was too limiting for certain cases and IO throughput could be bottlenecked by one CPU being fully occupied while others have idle cycles. While the new features required a lot of changes including restructuring locking, it didn't complicate the execution paths much. The unbound workqueue handling is now closer to per-cpu ones and the new features are implemented by simply associating a workqueue with different sets of backend worker pools without changing queue, execution or flush paths. As such, even though the amount of change is very high, I feel relatively safe in that it isn't likely to cause subtle issues with basic correctness of work item execution and handling. If something is wrong, it's likely to show up as being associated with worker pools with the wrong attributes or OOPS while workqueue attributes are being changed or during CPU hotplug. While this creates more backend worker pools, it doesn't add too many more workers unless, of course, there are many workqueues with unique combinations of attributes. Assuming everything else is the same, NUMA awareness costs an extra worker pool per NUMA node with online CPUs. There are also a couple things which are being routed outside the workqueue tree. - block tree pulled in workqueue for-3.10 so that writeback worker pool can be converted to unbound workqueue with sysfs control exposed. This simplifies the code, makes writeback workers NUMA-aware and allows tuning nice level and CPU affinity via sysfs. - The conversion to workqueue means that there's no 1:1 association between a specific worker, which makes writeback folks unhappy as they want to be able to tell which filesystem caused a problem from backtrace on systems with many filesystems mounted. This is resolved by allowing work items to set debug info string which is printed when the task is dumped. As this change involves unifying implementations of dump_stack() and friends in arch codes, it's being routed through Andrew's -mm tree." * 'for-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (84 commits) workqueue: use kmem_cache_free() instead of kfree() workqueue: avoid false negative WARN_ON() in destroy_workqueue() workqueue: update sysfs interface to reflect NUMA awareness and a kernel param to disable NUMA affinity workqueue: implement NUMA affinity for unbound workqueues workqueue: introduce put_pwq_unlocked() workqueue: introduce numa_pwq_tbl_install() workqueue: use NUMA-aware allocation for pool_workqueues workqueue: break init_and_link_pwq() into two functions and introduce alloc_unbound_pwq() workqueue: map an unbound workqueues to multiple per-node pool_workqueues workqueue: move hot fields of workqueue_struct to the end workqueue: make workqueue->name[] fixed len workqueue: add workqueue->unbound_attrs workqueue: determine NUMA node of workers accourding to the allowed cpumask workqueue: drop 'H' from kworker names of unbound worker pools workqueue: add wq_numa_tbl_len and wq_numa_possible_cpumask[] workqueue: move pwq_pool_locking outside of get/put_unbound_pool() workqueue: fix memory leak in apply_workqueue_attrs() workqueue: fix unbound workqueue attrs hashing / comparison workqueue: fix race condition in unbound workqueue free path workqueue: remove pwq_lock which is no longer used ... |

This mode was selected through the platform data, but it can be chosen by the driver internally without platform data configuration. How to decide the control mode: If the PWM period has specific value, the mode is PWM input. On the other hand, the mode is register-based. This mode selection is done on the _probe().

misc: generic on-chip SRAM allocation driver
This driver requests and remaps a memory region as configured in the device tree. It serves memory from this region via the genalloc API. It optionally enables the SRAM clock. Other drivers can retrieve the genalloc pool from a phandle pointing to this drivers' device node in the device tree. The allocation granularity is hard-coded to 32 bytes for now, to make the SRAM driver useful for the 6502 remoteproc driver. There is overhead for bigger SRAMs, where only a much coarser allocation granularity is needed: At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap to track allocations.

memcg: add memory.pressure_level events
With this patch userland applications that want to maintain the interactivity/memory allocation cost can use the pressure level notifications. The levels are defined like this: The "low" level means that the system is reclaiming memory for new allocations. Monitoring this reclaiming activity might be useful for maintaining cache level. Upon notification, the program (typically "Activity Manager") might analyze vmstat and act in advance (i.e. prematurely shutdown unimportant services). The "medium" level means that the system is experiencing medium memory pressure, the system might be making swap, paging out active file caches, etc. Upon this event applications may decide to further analyze vmstat/zoneinfo/memcg or internal memory usage statistics and free any resources that can be easily reconstructed or re-read from a disk. The "critical" level means that the system is actively thrashing, it is about to out of memory (OOM) or even the in-kernel OOM killer is on its way to trigger. Applications should do whatever they can to help the system. It might be too late to consult with vmstat or any other statistics, so it's advisable to take an immediate action. The events are propagated upward until the event is handled, i.e. the events are not pass-through. Here is what this means: for example you have three cgroups: A->B->C. Now you set up an event listener on cgroups A, B and C, and suppose group C experiences some pressure. In this situation, only group C will receive the notification, i.e. groups A and B will not receive it. This is done to avoid excessive "broadcasting" of messages, which disturbs the system and which is especially bad if we are low on memory or thrashing. So, organize the cgroups wisely, or propagate the events manually (or, ask us to implement the pass-through events, explaining why would you need them.) Performance wise, the memory pressure notifications feature itself is lightweight and does not require much of bookkeeping, in contrast to the rest of memcg features. Unfortunately, as of current memcg implementation, pages accounting is an inseparable part and cannot be turned off. The good news is that there are some efforts[1] to improve the situation; plus, implementing the same, fully API-compatible[2] interface for CONFIG_MEMCG=n case (e.g. embedded) is also a viable option, so it will not require any changes on the userland side.

mm: replace hardcoded 3% with admin_reserve_pages knob
Add an admin_reserve_kbytes knob to allow admins to change the hardcoded memory reserve to something other than 3%, which may be multiple gigabytes on large memory systems. Only about 8MB is necessary to enable recovery in the default mode, and only a few hundred MB are required even when overcommit is disabled. This affects OVERCOMMIT_GUESS and OVERCOMMIT_NEVER. admin_reserve_kbytes is initialized to min(3% free pages, 8MB) I arrived at 8MB by summing the RSS of sshd or login, bash, and top. Please see first patch in this series for full background, motivation, testing, and full changelog.

mm: limit growth of 3% hardcoded other user reserve
Add user_reserve_kbytes knob. Limit the growth of the memory reserved for other user processes to min(3% current process size, user_reserve_pages). Only about 8MB is necessary to enable recovery in the default mode, and only a few hundred MB are required even when overcommit is disabled. user_reserve_pages defaults to min(3% free pages, 128MB) I arrived at 128MB by taking the max VSZ of sshd, login, bash, and top ... then adding the RSS of each. This only affects OVERCOMMIT_NEVER mode. Background 1. user reserve __vm_enough_memory reserves a hardcoded 3% of the current process size for other applications when overcommit is disabled. This was done so that a user could recover if they launched a memory hogging process. Without the reserve, a user would easily run into a message such as: bash: fork: Cannot allocate memory 2. admin reserve Additionally, a hardcoded 3% of free memory is reserved for root in both overcommit 'guess' and 'never' modes. This was intended to prevent a scenario where root-cant-log-in and perform recovery operations. Note that this reserve shrinks, and doesn't guarantee a useful reserve. Motivation The two hardcoded memory reserves should be updated to account for current memory sizes. Also, the admin reserve would be more useful if it didn't shrink too much. When the current code was originally written, 1GB was considered "enterprise". Now the 3% reserve can grow to multiple GB on large memory systems, and it only needs to be a few hundred MB at most to enable a user or admin to recover a system with an unwanted memory hogging process. I've found that reducing these reserves is especially beneficial for a specific type of application load: * single application system * one or few processes (e.g. one per core) * allocating all available memory * not initializing every page immediately * long running I've run scientific clusters with this sort of load. A long running job sometimes failed many hours (weeks of CPU time) into a calculation. They weren't initializing all of their memory immediately, and they weren't using calloc, so I put systems into overcommit 'never' mode. These clusters run diskless and have no swap. However, with the current reserves, a user wishing to allocate as much memory as possible to one process may be prevented from using, for example, almost 2GB out of 32GB. The effect is less, but still significant when a user starts a job with one process per core. I have repeatedly seen a set of processes requesting the same amount of memory fail because one of them could not allocate the amount of memory a user would expect to be able to allocate. For example, Message Passing Interfce (MPI) processes, one per core. And it is similar for other parallel programming frameworks. Changing this reserve code will make the overcommit never mode more useful by allowing applications to allocate nearly all of the available memory. Also, the new admin_reserve_kbytes will be safer than the current behavior since the hardcoded 3% of available memory reserve can shrink to something useless in the case where applications have grabbed all available memory. Risks * "bash: fork: Cannot allocate memory" The downside of the first patch-- which creates a tunable user reserve that is only used in overcommit 'never' mode--is that an admin can set it so low that a user may not be able to kill their process, even if they already have a shell prompt. Of course, a user can get in the same predicament with the current 3% reserve--they just have to launch processes until 3% becomes negligible. * root-cant-log-in problem The second patch, adding the tunable rootuser_reserve_pages, allows the admin to shoot themselves in the foot by setting it too small. They can easily get the system into a state where root-can't-log-in. However, the new admin_reserve_kbytes will be safer than the current behavior since the hardcoded 3% of available memory reserve can shrink to something useless in the case where applications have grabbed all available memory. Alternatives * Memory cgroups provide a more flexible way to limit application memory. Not everyone wants to set up cgroups or deal with their overhead. * We could create a fourth overcommit mode which provides smaller reserves. The size of useful reserves may be drastically different depending on the whether the system is embedded or enterprise. * Force users to initialize all of their memory or use calloc. Some users don't want/expect the system to overcommit when they malloc. Overcommit 'never' mode is for this scenario, and it should work well. The new user and admin reserve tunables are simple to use, with low overhead compared to cgroups. The patches preserve current behavior where 3% of memory is less than 128MB, except that the admin reserve doesn't shrink to an unusable size under pressure. The code allows admins to tune for embedded and enterprise usage. FAQ * How is the root-cant-login problem addressed? What happens if admin_reserve_pages is set to 0? Root is free to shoot themselves in the foot by setting admin_reserve_kbytes too low. On x86_64, the minimum useful reserve is: 8MB for overcommit 'guess' 128MB for overcommit 'never' admin_reserve_pages defaults to min(3% free memory, 8MB) So, anyone switching to 'never' mode needs to adjust admin_reserve_pages. * How do you calculate a minimum useful reserve? A user or the admin needs enough memory to login and perform recovery operations, which includes, at a minimum: sshd or login + bash (or some other shell) + top (or ps, kill, etc.) For overcommit 'guess', we can sum resident set sizes (RSS) because we only need enough memory to handle what the recovery programs will typically use. On x86_64 this is about 8MB. For overcommit 'never', we can take the max of their virtual sizes (VSZ) and add the sum of their RSS. We use VSZ instead of RSS because mode forces us to ensure we can fulfill all of the requested memory allocations-- even if the programs only use a fraction of what they ask for. On x86_64 this is about 128MB. When swap is enabled, reserves are useful even when they are as small as 10MB, regardless of overcommit mode. When both swap and overcommit are disabled, then the admin should tune the reserves higher to be absolutley safe. Over 230MB each was safest in my testing. * What happens if user_reserve_pages is set to 0? Note, this only affects overcomitt 'never' mode. Then a user will be able to allocate all available memory minus admin_reserve_kbytes. However, they will easily see a message such as: "bash: fork: Cannot allocate memory" And they won't be able to recover/kill their application. The admin should be able to recover the system if admin_reserve_kbytes is set appropriately. * What's the difference between overcommit 'guess' and 'never'? "Guess" allows an allocation if there are enough free + reclaimable pages. It has a hardcoded 3% of free pages reserved for root. "Never" allows an allocation if there is enough swap + a configurable percentage (default is 50) of physical RAM. It has a hardcoded 3% of free pages reserved for root, like "Guess" mode. It also has a hardcoded 3% of the current process size reserved for additional applications. * Why is overcommit 'guess' not suitable even when an app eventually writes to every page? It takes free pages, file pages, available swap pages, reclaimable slab pages into consideration. In other words, these are all pages available, then why isn't overcommit suitable? Because it only looks at the present state of the system. It does not take into account the memory that other applications have malloced, but haven't initialized yet. It overcommits the system. Test Summary There was little change in behavior in the default overcommit 'guess' mode with swap enabled before and after the patch. This was expected. Systems run most predictably (i.e. no oom kills) in overcommit 'never' mode with swap enabled. This also allowed the most memory to be allocated to a user application. Overcommit 'guess' mode without swap is a bad idea. It is easy to crash the system. None of the other tested combinations crashed. This matches my experience on the Roadrunner supercomputer. Without the tunable user reserve, a system in overcommit 'never' mode and without swap does not allow the admin to recover, although the admin can. With the new tunable reserves, a system in overcommit 'never' mode and without swap can be configured to: 1. maximize user-allocatable memory, running close to the edge of recoverability 2. maximize recoverability, sacrificing allocatable memory to ensure that a user cannot take down a system Test Description Fedora 18 VM - 4 x86_64 cores, 5725MB RAM, 4GB Swap System is booted into multiuser console mode, with unnecessary services turned off.

Tracing updates for Linux 3.10
Along with the usual minor fixes and clean ups there are a few major changes with this pull request. 1) Multiple buffers for the ftrace facility This feature has been requested by many people over the last few years. I even heard that Google was about to implement it themselves. I finally had time and cleaned up the code such that you can now create multiple instances of the ftrace buffer and have different events go to different buffers. This way, a low frequency event will not be lost in the noise of a high frequency event. Note, currently only events can go to different buffers, the tracers (ie. function, function_graph and the latency tracers) still can only be written to the main buffer. 2) The function tracer triggers have now been extended. The function tracer had two triggers. One to enable tracing when a function is hit, and one to disable tracing. Now you can record a stack trace on a single (or many) function(s), take a snapshot of the buffer (copy it to the snapshot buffer), and you can enable or disable an event to be traced when a function is hit. 3) A perf clock has been added. A "perf" clock can be chosen to be used when tracing. This will cause ftrace to use the same clock as perf uses, and hopefully this will make it easier to interleave the perf and ftrace data for analysis. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQEcBAABAgAGBQJRfnTPAAoJEOdOSU1xswtMqYYH/1WIdrwXmxHflErnYkCIr3sU QtYae2K5A1HcgiqOvRJrdWMOt016iMx5CaQQyBFM1vvMiPY0sTWRmwNxDfZzz9LN 10jRvWEzZSLtzl+a9mkFWLEpr5nR/QODOxkWFCnRWscp46sp04LSTxGDYsOnPQZB sam/AQ1h4xA+DqDBChm9BDEUEPorGleTlN54LBaCGgSFGvrbF+eAg2s4vHNAQAvQ 8d5xjSE9zC7J+FqbVxvJTbKI3+EqKL6hMsJKsKfi0SI+FuxBaFMSltXck5zKyTI4 HpNJzXCmw+v90Tju7oMkPHh6RTbESPCHoGU+wqE52fM6m7oScVeuI/kfc6USwU4= =W1n+ -----END PGP SIGNATURE----- Merge tag 'trace-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "Along with the usual minor fixes and clean ups there are a few major changes with this pull request. 1) Multiple buffers for the ftrace facility This feature has been requested by many people over the last few years.

These are the pinctrl changes for v3.10:
- Patrice Chotard contributed a new configuration debugfs interface and reintroduced fine-grained locking into the core: instead of having a "big pinctrl lock" we have a per-controller lock and specialized locks for the global controller and pinctrl handle lists. - Haoijan Zhuang deleted all the PXA and MMP2 pinctrl drivers and replaced them with pinctrl-single (which is also used by other SoCs) so we are gaining consolidation. The platform particulars now come in through the device tree. - Haoijan also added support for generic pin config into the pinctrl-single driver which is another big consolidation win. - Finally also GPIO ranges are now supported by the pinctrl-single driver. - Tomasz Figa contributed a new Samsung S3C pinctrl driver, bringing more of the older Samsung platforms under the pinctrl umbrella and out of arch/arm. - Maxime Ripard contributed new Allwinner A10/A13 drivers. - Sachin Kamat, Wei Yongjun and Axel Lin did a lot of cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJRfmmSAAoJEEEQszewGV1z2BEQAKZ5RhNu+Rc0AoDxYlVWg6bf GBepmdjHXvYSlFltIu7/ti0ttGGfU/F5j8eqGQDBZl9WnYu9WEglPp7EdBNn4/oo fVtqwWH0tAXbk3BNn7tpufWQh0HpFnmkMqtqtfM9HqvRLnw7HISLYzSjBO41rTiw +Cpx/FMogRK1ABKyWvoddXQnQ2ApJwLlgaJ95vkuaQe3i0PVz39e/GdKW4aM7Y6N ksim0GXGLuOObdp42b1Ib5/MdHJKCQfwmtOd+d017uREXxR5u5y49oyjYRTeHcjk qMqKUL3c+HNN1b39I9O2LoWuKAALN6WSOl+o+o+GXLHHe96i8nwp59f7Q7No2v3J x1bCCfbJ1yoRfmdpA/P9DYFj7taiEhCfVKf34NJcw5ZhRk3soJ9BpyYqhPAlEdgD pDjalTeMRJORo8ZuOpmR8f3sFNd6XnO84NWFoPOPiRQJYKYCUehY5bOVP8nfYTXJ A9VWS0ZCFFLS6wU2kSU++gVg0sFToCbYCEP6fSnl9n48U56jXUgNt36+HL69bGw/ Du7WdHilNuMfGM3HhAf2dM7NlzSyIbUwagBJHPVa4iF/pDF5BeCdsP983INfomuR SQv25JfOMGB1iIyC87j9+1Mzuc2ouFV/QXBsTtmiyYmIaWhf8SGeioyXGfqUiQmE 6sZKS27MYtAKQHmwvf5U =CyMU -----END PGP SIGNATURE----- Merge tag 'pinctrl-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pinctrl update from Linus Walleij: "These are the pinctrl changes for v3.10: - Patrice Chotard contributed a new configuration debugfs interface and reintroduced fine-grained locking into the core: instead of having a "big pinctrl lock" we have a per-controller lock and specialized locks for the global controller and pinctrl handle lists. - Haoijan Zhuang deleted all the PXA and MMP2 pinctrl drivers and replaced them with pinctrl-single (which is also used by other SoCs) so we are gaining consolidation.
