mm/rmap: extend rmap_walk_xxx() to cope with different cases
There are a lot of common parts in traversing functions, but there are also a little of uncommon parts in it. By assigning proper function pointer on each rmap_walker_control, we can handle these difference correctly. Following are differences we should handle. 1. difference of lock function in anon mapping case 2. nonlinear handling in file mapping case 3. prechecked condition: checking memcg in page_referenced(), checking VM_SHARE in page_mkclean() checking temporary vma in try_to_unmap() 4. exit condition: checking page_mapped() in try_to_unmap() So, in this patch, I introduce 4 function pointers to handle above differences.

memblock, mem_hotplug: make memblock skip hotpluggable regions if needed
Linux kernel cannot migrate pages used by the kernel. As a result, hotpluggable memory used by the kernel won't be able to be hot-removed. To solve this problem, the basic idea is to prevent memblock from allocating hotpluggable memory for the kernel at early time, and arrange all hotpluggable memory in ACPI SRAT(System Resource Affinity Table) as ZONE_MOVABLE when initializing zones. In the previous patches, we have marked hotpluggable memory regions with MEMBLOCK_HOTPLUG flag in memblock.memory. In this patch, we make memblock skip these hotpluggable memory regions in the default top-down allocation function if movable_node boot option is specified.

memblock, numa: introduce flags field into memblock
There is no flag in memblock to describe what type the memory is. Sometimes, we may use memblock to reserve some memory for special usage. And we want to know what kind of memory it is. So we need a way to In hotplug environment, we want to reserve hotpluggable memory so the kernel won't be able to use it. And when the system is up, we have to free these hotpluggable memory to buddy. So we need to mark these memory first. In order to do so, we need to mark out these special memory in memblock. In this patch, we introduce a new "flags" member into memblock_region: struct memblock_region { phys_addr_t base; phys_addr_t size; unsigned long flags; /* This is new. */ #ifdef CONFIG_HAVE_MEMBLOCK_NODE_MAP int nid; #endif }; This patch does the following things: 1) Add "flags" member to memblock_region. 2) Modify the following APIs' prototype: memblock_add_region() memblock_insert_region() 3) Add memblock_reserve_region() to support reserve memory with flags, and keep memblock_reserve()'s prototype unmodified. 4) Modify other APIs to support flags, but keep their prototype unmodified.

mm: add overcommit_kbytes sysctl variable
Some applications that run on HPC clusters are designed around the availability of RAM and the overcommit ratio is fine tuned to get the maximum usage of memory without swapping. With growing memory, the 1%-of-all-RAM grain provided by overcommit_ratio has become too coarse for these workload (on a 2TB machine it represents no less than 20GB). This patch adds the new overcommit_kbytes sysctl variable that allow a much finer grain.

mm: create a separate slab for page->ptl allocation
If DEBUG_SPINLOCK and DEBUG_LOCK_ALLOC are enabled spinlock_t on x86_64 is 72 bytes. For page->ptl they will be allocated from kmalloc-96 slab, so we loose 24 on each. An average system can easily allocate few tens thousands of page->ptl and overhead is significant. Let's create a separate slab for page->ptl allocation to solve this. To make sure that it really works this time, some numbers from my test machine (just booted, no load): Before: # grep '^\(kmalloc-96\|page->ptl\)' /proc/slabinfo kmalloc-96 31987 32190 128 30 1 : tunables 120 60 8 : slabdata 1073 1073 92 After: # grep '^\(kmalloc-96\|page->ptl\)' /proc/slabinfo page->ptl 27516 28143 72 53 1 : tunables 120 60 8 : slabdata 531 531 9 kmalloc-96 3853 5280 128 30 1 : tunables 120 60 8 : slabdata 176 176 0 Note that the patch is useful not only for debug case, but also for PREEMPT_RT, where spinlock_t is always bloated.

mm: get rid of unnecessary pageblock scanning in setup_zone_migrate_reserve
Yasuaki Ishimatsu reported memory hot-add spent more than 5 _hours_ on 9TB memory machine since onlining memory sections is too slow. And we found out setup_zone_migrate_reserve spent >90% of the time. The problem is, setup_zone_migrate_reserve scans all pageblocks unconditionally, but it is only necessary if the number of reserved block was reduced (i.e. memory hot remove). Moreover, maximum MIGRATE_RESERVE per zone is currently 2. It means that the number of reserved pageblocks is almost always unchanged. This patch adds zone->nr_migrate_reserve_block to maintain the number of MIGRATE_RESERVE pageblocks and it reduces the overhead of setup_zone_migrate_reserve dramatically. The following table shows time of onlining a memory section.

mm: tail page refcounting optimization for slab and hugetlbfs
This skips the _mapcount mangling for slab and hugetlbfs pages. The main trouble in doing this is to guarantee that PageSlab and PageHeadHuge remains constant for all get_page/put_page run on the tail of slab or hugetlbfs compound pages. Otherwise if they're set during get_page but not set during put_page, the _mapcount of the tail page would underflow. PageHeadHuge will remain true until the compound page is released and enters the buddy allocator so it won't risk to change even if the tail page is the last reference left on the page. PG_slab instead is cleared before the slab frees the head page with put_page, so if the tail pin is released after the slab freed the page, we would have a problem. But in the slab case the tail pin cannot be the last reference left on the page. This is because the slab code is free to reuse the compound page after a kfree/kmem_cache_free without having to check if there's any tail pin left. In turn all tail pins must be always released while the head is still pinned by the slab code and so we know PG_slab will be still set too.

mm: thp: optimize compound_trans_huge
Currently we don't clobber page_tail->first_page during split_huge_page, so compound_trans_head can be set to compound_head without adverse effects, and this mostly optimizes away a smp_rmb. It looks worthwhile to keep around the implementation that doesn't relay on page_tail->first_page not to be clobbered, because it would be necessary if we'll decide to enforce page->private to zero at all times whenever PG_private is not set, also for anonymous pages. For anonymous pages enforcing such an invariant doesn't matter as anonymous pages don't use page->private so we can get away with this microoptimization.

fsnotify: do not share events between notification groups
Currently fsnotify framework creates one event structure for each notification event and links this event into all interested notification groups. This is done so that we save memory when several notification groups are interested in the event. However the need for event structure shared between inotify & fanotify bloats the event structure so the result is often higher memory consumption. Another problem is that fsnotify framework keeps path references with outstanding events so that fanotify can return open file descriptors with its events. This has the undesirable effect that filesystem cannot be unmounted while there are outstanding events - a regression for inotify compared to a situation before it was converted to fsnotify framework. For fanotify this problem is hard to avoid and users of fanotify should kind of expect this behavior when they ask for file descriptors from notified files. This patch changes fsnotify and its users to create separate event structure for each group. This allows for much simpler code (~400 lines removed by this patch) and also smaller event structures. For example on 64-bit system original struct fsnotify_event consumes 120 bytes, plus additional space for file name, additional 24 bytes for second and each subsequent group linking the event, and additional 32 bytes for each inotify group for private data. After the conversion inotify event consumes 48 bytes plus space for file name which is considerably less memory unless file names are long and there are several groups interested in the events (both of which are uncommon). Fanotify event fits in 56 bytes after the conversion (fanotify doesn't care about file names so its events don't have to have it allocated). A win unless there are four or more fanotify groups interested in the event. The conversion also solves the problem with unmount when only inotify is used as we don't have to grab path references for inotify events.

sound updates for 3.14-rc1
It was holiday season, so no wonder that there are little changes in framework level, although diffstat shows quite many changes spreaded over sound/* directories. Most of changes are cleanups, code refactoring and fixes. Some highlights: - Removal of OSS sleep_on usages by Arnd - Simplified memalloc helper codes, drop obsoleted features; now it's built into PCM driver instead of an individual module - Warn if PCM buffer preallocation fails, which will show page allocation issues more clearly - Compress offload API updates for sample rates by Vinod - PCM glitch workaround on ctxfi emu20k1 by Sarah - Drop cs46xx DSP blobs, using firmware loader now - USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and Focusrite Saffire 6 HD-audio specifics: - Standardize Kconfigs of HD-audio codec drivers; now "make localmodconfig" recognizes configs properly (finally!) - Parallel PM implementation by Mengdong - BayleyBay/ValleyView2 board fixups - Broadwell audio support - Runtime PM improvement (PantherPoint, etc) - Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell AiO click noise fixes, Dell headset mic fixes, etc - Automatic bind with HDMI codec parser without generic parser - More AD codec fixes (since 3.12 regression) including the automatic stereo mix support - Common Thinkpad ACPI helper for Realtek and Conexant codecs ASoC specifics: - Update to the generic DMA code to support deferred probe and managed resources - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090 and Analog Devices AXI I2S and S/PDIF controller IPs - Device tree support for the simple card, max98090 and cs42l52 - Conversion of the Samsung drivers to native dmaengine, making them multiplatform compatible and hopefully helping keep them more modern and up to date. - More regmap conversions, including a very welcome one for twl6040 from Peter Ujfalusi - A big overhaul of the DaVinci drivers also from Peter Ujfalusi - Lots of DMA updates from Lars-Peter - Improvements to the constraints handling code from Lars-Peter - A very helpful conversion of the TWL4030 driver to regmap from Peter - A new driver for the Freescale ESAI controller from Nicolin Chen - Conversion of some of the drivers to use params_width() - Extensions to DPCM for use with compressed audio from Liam -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJS3ocNAAoJEGwxgFQ9KSmkZEcP/3ImC7SrUC8NbCJF51tm31jk Ed6eKNEJPcVEbUkZ6QN215w8OkgGCXnxMge1Mhu5VGFJiIjmdtls297DqJAXUL3d l3/icCeYK7BN7ocMyaFRnwUipRtSiI0YuuU5cIcdbAoSrI8gtc+yZES82ivjOY4i cFs/owDc5nqTNtx414N14a0NQOTJU5gMNjOVqCno8VLsUUUlg3nEY0kyHKiBNe4O EqYmHHS2L4xu3tqxmh8pvd82OUnO53rMJXRntU6nuw1sgY7o+4pjmi3k10l1SHpH Rv0dB8PunY72AnxPMPORISKHJ3isKPz0QdZVtdj0+WrFUwD1vrFE3Yktq3hYQvwd NrOcMoEosQQhDcD74SSt1xfKVpW+gJazN4154VK/O2PKdNHLdc3/4rw95tYA8ywO /jnDH+qNlzHSrAdq2Fj21FfTKOYvow8RBB+Rp05RymKESwJ9sk0yLLN1QgDoJXwW kNBH6SxMxhaHOch0PzXidErydxnB2+j59i485DmJlI1GsjJTMFZvm8f85OlNstrn ad5OsXKfBkS78oT5vBeDkp5uH56hPiyP89lhnd+cE/MgjBHHnQliJ8thLumgUjN+ vf6VGnpJywacH/VYrA2v8xKj514Q0CgsEydYtq5Z4J6WQVKrECOYlgYgpbJt6dsC WE9DYZECRVCp74N8WB+z =IWy2 -----END PGP SIGNATURE----- Merge tag 'sound-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "It was holiday season, so no wonder that there are little changes in framework level, although diffstat shows quite many changes spreaded over sound/* directories.

GPIO tree bulk changes for v3.14
A big set this merge window, as we have much going on in this subsystem. Major changes this time: - Some core improvements and cleanups to the new GPIO descriptor API. This seems to be working now so we can start the exodus to this API, moving gradually away from the global GPIO numberspace. - Incremental improvements to the ACPI GPIO core, and move the few GPIO ACPI clients we have to the GPIO descriptor API right *now* before we go any further. We actually managed to contain this *before* we started to litter the kernel with yet another hackish global numberspace for the ACPI GPIOs, which is a big win. - The RFkill GPIO driver and all platforms using it have been migrated to use the GPIO descriptors rather than fixed number assignments. Tegra machine has been migrated as part of this. - New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x. Those should be really good examples of how I expect a nice GPIO driver to look these days. - Do away with custom GPIO implementations on a major part of the ARM machines: ks8695, lpc32xx, mv78xx0. Make a first step towards the same in the horribly convoluted Samsung S3C include forest. We expect to continue to clean this up as we move forward. - Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and lynxpoint. This makes the GPIOlib core aware that a certain GPIO line is used for IRQs and can then enforce some semantics such as disallowing a GPIO line marked as in use for IRQ to be switched to output mode. - Drop all use of irq_set_chip_and_handler_name(). The name provided in these cases were just unhelpful tags like "mux" or "demux". - Extend the MCP23s08 driver to handle interrupts. - Minor incremental improvements for rcar, lynxpoint, em 74x164 and msm drivers. - Some non-urgent bug fixes here and there, duplicate #includes and that usual kind of cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJS3i/MAAoJEEEQszewGV1zVB8P/Rjzgx8To0gQPn49M4u/A1Mk mAzpUoKa05ILTKBm/bpWPYZPpg9PDqUxOYPsIDEAkc70BKMPTXxrYiE+LSfIzwaJ a8IRwOzNL7Iwc+zPNS/GrmRJyxymb4lmMD/fypk/YaumZ6j4Hbo+9R8Zct9gbZ5Q ZbKtz6kLhbkbNCc71bVMgk6yacSBx1ak8Xpd12HlW85NgOCoBj7/DI1Lb61x1ImY NYpSpmtfGGTkQLtBl5dTLefZOvL1dKSct9TMOsA2jzNqf3zA1YA6XOxPGHK/qtjq 3s9cN1sIVF/g7sm1+qoKXe0OTQrXHT7SX8BH9/tb3MiKO8ItactlQUJlYNR3WFSN zm1PNe5zWr+GWzV0iUrqoMN4XX8nThiFDOxZpOwBTZcUD6qtDFIZp41M3qxwFTbJ hCtSQ8gUO1Ce+xtOQYYOwEkRS7FZa1Z+p/lendTFuGDh6DcXy97SrKkTktM4Q98B LhqrwUzCdES0ecNDi2+P5y4Fc7M0cMMn9SnFvbSBObLB89TF9uzMIn8jUBCZMvrM eAeZlRBYk8F+6F12higaWqZyiBKIEubXo/Z8T0L2KEDm/z/ddJvhQgBKvWlf3rqi RToD446rda+RhFBnxLZ3mTui5nZ2WyKTOqhVqeBuriJhE/cTUaQHUBUrbOwx20kE Xb9mQ2n3GRk2157n1CLY =lW2i -----END PGP SIGNATURE----- Merge tag 'gpio-v3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO tree bulk changes from Linus Walleij: "A big set this merge window, as we have much going on in this subsystem.

The name provided in these cases were just unhelpful tags like "mux" or "demux". - Extend the MCP23s08 driver to handle interrupts. - Minor incremental improvements for rcar, lynxpoint, em 74x164 and msm drivers. - Some non-urgent bug fixes here and there, duplicate #includes and that usual kind of cleanups" Fix up broken Kconfig file manually to make this all compile. * tag 'gpio-v3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (71 commits) gpio: mcp23s08: fix casting caused build warning gpio: mcp23s08: depend on OF_GPIO gpio: mcp23s08: Add irq functionality for i2c chips ARM: S5P[v210|c100|64x0]: Fix build error gpio: pxa: clamp gpio get value to [0,1] ARM: s3c24xx: explicit dependency on <plat/gpio-cfg.h> ARM: S3C[24|64]xx: move includes back under <mach/> scope Documentation / ACPI: update to GPIO descriptor API gpio / ACPI: get rid of acpi_gpio.h gpio / ACPI: register to ACPI events automatically mmc: sdhci-acpi: convert to use GPIO descriptor API ARM: s3c24xx: fix build error gpio: f7188x: set can_sleep attribute gpio: samsung: Update documentation gpio: samsung: Remove hardware.h inclusion gpio: xtensa: depend on HAVE_XTENSA_GPIO32 gpio: clps711x: Enable driver compilation with COMPILE_TEST gpio: clps711x: Use of_match_ptr() net: rfkill: gpio: convert to descriptor-based GPIO interface leds: s3c24xx: Fix build failure ... |

mfd: Add LP3943 MFD driver
LP3943 has 16 output pins which can be used as GPIO expander and PWM generator. * Regmap I2C interface for R/W LP3943 registers * Atomic operations for output pin assignment The driver should check whether requested pin is available or not. If the pin is already used, pin request returns as a failure. A driver data, 'pin_used' is checked when gpio_request() and pwm_request() are called. If the pin is available, then pin_used is set. And it is cleared when gpio_free() and pwm_free(). * Device tree support Compatible strings for GPIO and PWM driver. LP3943 platform data is PWM related, so parsing the device tree is implemented in the PWM driver. Signed-off-by: Milo Kim <milo.kim@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> |

Driver core / sysfs patches for 3.14-rc1
Here's the big driver core and sysfs patch set for 3.14-rc1. There's a lot of work here moving sysfs logic out into a "kernfs" to allow other subsystems to also have a virtual filesystem with the same attributes of sysfs (handle device disconnect, dynamic creation / removal as needed / unneeded, etc. This is primarily being done for the cgroups filesystem, but the goal is to also move debugfs to it when it is ready, solving all of the known issues in that filesystem as well. The code isn't completed yet, but all should be stable now (there is a big section that was reverted due to problems found when testing.) There's also some other smaller fixes, and a driver core addition that allows for a "collection" of objects, that the DRM people will be using soon (it's in this tree to make merges after -rc1 easier.)
