IOMMU Updates for Linux v3.19
This time with: * A new IOMMU-API call: iommu_map_sg() to map multiple non-contiguous pages into an IO address space with only one API call. This allows certain optimizations in the IOMMU driver. * DMAR device hotplug in the Intel VT-d driver. It is now possible to hotplug the IOMMU itself. * A new IOMMU driver for the Rockchip ARM platform. * Couple of cleanups and improvements in the OMAP IOMMU driver. * Nesting support for the ARM-SMMU driver. * Various other small cleanups and improvements. Please note that this time some branches were also pulled into other trees, like the DRI and the Tegra tree. The VT-d branch was also pulled into tip/x86/apic. Some patches for the AMD IOMMUv2 driver are not in the IOMMU tree but were merged by Andrew (or finally ended up in the DRI tree). -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJUiwktAAoJECvwRC2XARrjweAP/Rr4igltfUFjfSp7iQBoQxQP qmFv3/A6f0gxfJ2IhA8ZnmJwoNAxYnqCEl+vA0FYDnXxO6CCHXWkeO5NprwU+fuG BZDn4lmg+GhpTCXS5668l+MZxtqZCMaCQbK5pm+b+uk8qkXznlVs2Nb00BBL/TTo 4WhyLPbNnAfQkBGTFf47QqSi5YYPmJ44TvIcHPsFBz0dTesO7JKg9c4HpyxUmnMs 7VDPWJmiuTJ+/UISkFzxHVw9GcL6XXhdu70XEFrVo6wnXRDTqbDtBUP8vnghnqwG kOIYrY+7HO3iEDaiiSGqxeMH5Uac2yIlQi4W4TXWg7WpKenZPqnwZusD50vO3HyB 9L4VIL14gbgV6s+/9YNDYR494d9+xRjGMO4FAIIWnVFmE98+zqHpc8OaF0azY4N7 3vxlM6VGvWytTmTpU/J/VMhwFPo/6QHdGpBa0k0+ACMQ8LTPt+Q7o+fTBcDCgnJW SAa5AGruMBFgZ2RtN9bgAGxAhuSPmh7pD+va5vUzvAngY0o6tamblh9G6Sk26nka y0RZVJ+vplP3jvLXMy9SByxGgBv3/iNF8YUd7Zp0rpZyW8KElRm4m9xuvxzu9cIW 3SR+/pEhvqqXo48XS040FScD65QjGbKWGuiH+Zs+6Ij4MY6xxCAlf7EV+8DIiTO5 LcI66Fk6oFzFKz2BRBpn =x7Ei -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "This time with: - A new IOMMU-API call: iommu_map_sg() to map multiple non-contiguous pages into an IO address space with only one API call.

powerpc updates for 3.19
Some nice cleanups like removing bootmem, and removal of __get_cpu_var(). There is one patch to mm/gup.c. This is the generic GUP implementation, but is only used by us and arm(64). We have an ack from Steve Capper, and although we didn't get an ack from Andrew he told us to take the patch through the powerpc tree. There's one cxl patch. This is in drivers/misc, but Greg said he was happy for us to manage fixes for it. There is an infrastructure patch to support an IPMI driver for OPAL. That patch also appears in Corey Minyard's IPMI tree, you may see a conflict there. There is also an RTC driver for OPAL. We weren't able to get any response from the RTC maintainer, Alessandro Zummo, so in the end we just merged the driver. The usual batch of Freescale updates from Scott. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJUiSTSAAoJEFHr6jzI4aWAirQP/3rIEng0LzLu5kW2zkGylIaM SNDum1vze3mHiTFl+CFcSIGpC1UEULoB49HA+2oE/ExKpIceG6lpL2LP+wNh2FW5 mozjMjS6mZt4w1Fu1D2ZtgQc3O1T1pxkqsnZmPa8gVf5k5d5IQNPY6yB0pgVWwbV gwBKxe4VwPAzJjppE9i9MDhNTJwmHZq0lI8XuoTXOOU/f+4G1WxmjrbyveQ7cRP5 i/sq2cKjxpWA+KDeIXo0GR0DpXR7qMeAvFX5xXY7oKuUJIFDM4kSHfmMYP6qLf5c 2vlsJqHVqfOgQdve41z1ooaPzNtg7ezVo+VqqguSgtSgwy2JUo/uHpnzz3gD1Olo AP5+6xj8LZac0rTPxF4n4Hoyrp7AaaFjEFt1zqT9PWniZW4B41wtia0QORBNUf1S UEmKAC9T3WZJ47mH7WMSadtOPF9E3Yd/zuiPD4udtptCNKPbr6/k1MpJPIW2D4Rn BJ0QZTRd7V0yRofXxZtHxaMxq8pWd/Tip7J/zr/ghz+ulnH8BuFamuhCCLuJlESU +A2PMfuseyTMpH9sMAmmTwSGPDKjaUFWvmFvY/n88NZL7r2LlomNrDWFSSQOIHUP FxjYmjUMpZeexsfyRdgFV/INhYC3o3cso2fRGO45YK6nkxNnjNFEBS6WhQLvNLBu sknd1WjXkuJtoMC15SrQ =jvyT -----END PGP SIGNATURE----- Merge tag 'powerpc-3.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux Pull powerpc updates from Michael Ellerman: "Some nice cleanups like removing bootmem, and removal of __get_cpu_var().

Pull networking updates from David Miller: 1) New offloading infrastructure and example 'rocker' driver for offloading of switching and routing to hardware. This work was done by a large group of dedicated individuals, not limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend, Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu 2) Start making the networking operate on IOV iterators instead of modifying iov objects in-situ during transfers. Thanks to Al Viro and Herbert Xu. 3) A set of new netlink interfaces for the TIPC stack, from Richard Alpe. 4) Remove unnecessary looping during ipv6 routing lookups, from Martin KaFai Lau. 5) Add PAUSE frame generation support to gianfar driver, from Matei Pavaluca. 6) Allow for larger reordering levels in TCP, which are easily achievable in the real world right now, from Eric Dumazet. 7) Add a variable of napi_schedule that doesn't need to disable cpu interrupts, from Eric Dumazet. 8) Use a doubly linked list to optimize neigh_parms_release(), from Nicolas Dichtel. 9) Various enhancements to the kernel BPF verifier, and allow eBPF programs to actually be attached to sockets.

pstore-ram: Allow optional mapping with pgprot_noncached
On some ARMs the memory can be mapped pgprot_noncached() and still be working for atomic operations. As pointed out by Colin Cross <ccross@android.com>, in some cases you do want to use pgprot_noncached() if the SoC supports it to see a debug printk just before a write hanging the system. On ARMs, the atomic operations on strongly ordered memory are implementation defined. So let's provide an optional kernel parameter for configuring pgprot_noncached(), and use pgprot_writecombine() by default.

sound updates for 3.19-rc1
This became a fairly large pull request. In addition to the usual driver updates / fixes, there have been a high amount of cleanups in ASoC area, as well as control API helpers and kernel documentations fixes touching through the whole tree. In the driver side, the biggest changes are the support for new Intel SoC found on new x86 machines, and the updates of FireWire dice and oxfw drivers. Some remarkable items are below: * ALSA core - PCM mmap code cleanup, removal of arch-dependent codes - PCM xrun injection support - PCM hwptr tracepoint support - Refactoring of snd_pcm_action(), simplification of PCM locking - Robustified sequecner auto-load functionality - New control API helpers and lots of cleanups along with them - Lots of kerneldoc fixes and cleanups * USB-audio - The mixer resume code was largely rewritten, and the devices with quirks are resumed properly. - New hardware support: Focusrite Scarlett, Digidesign Mbox1, Denon/Marantz DACs, Zoom R16/24 * FireWire - DICE driver updates with better duplex and sync support, including MIDI support - New OXFW driver for Oxford Semiconductor FW970/971 chipset, including the previous LaCie Speakers device. Fullduplex and MIDI support included as well as DICE driver. * HD-audio - Refactoring the driver-caps quirk handling in snd-hda-intel - More consistent control names representing the topology better - Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic fix, ASUS Z99He laptop EAPD * ASoC - Conversion of AC'97 drivers to use regmap, bringing us closer to the removal of the ASoC level I/O code - Clean up a lot of old drivers that were open coding things that have subsequently been implemented in the core - Some DAPM performance improvements - Removal of the now seldom used CODEC mutex - Lots of updates for the newer Intel SoC support, including support for the DSP and some Cherrytrail and Braswell machine drivers - Support for Samsung boards using rt5631 as the CODEC - Removal of the obsolete AFEB9260 machine driver - Driver support for the TI TS3A227E headset driver used in some Chrombeooks * Others - ASIHPI driver update and cleanups - Lots of dev_*() printk conversions - Lots of trivial cleanups for the codes spotted by Coccinelle -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJUiYaqAAoJEGwxgFQ9KSmkeo0P/2aDx2w8iVi8n7Og/7VBubkm VZkk08IOpP3h1ojyQRsBQPI0H5AquqQTZN1TJUDcy+6PD9vckYYcag9JWhA+0RBr I+BfTMLB3E4umIkzOjxeoyOzheL7GoZ+eZYEm8DkAhaue+cFhjNJz+S6g8ENkxJ9 lSjErXQxyiowc39I0v1WBZcuq6glX1psEsVup9U8m7KhNx6lexj28A2MkqicW4hs DZE6pYrk57W7y3+/NWxaBiglrItvScBAPpPqoyDm9zuDNTmAtGjf1uMRmRyHe30Z iunHXki8Fc2yBBapmfYrcLC2jyIyZykcxniF8Hd4nXUvddisFUEFFhNmB6v392d0 4/NXSqTnsq48vm0Ezjia2LySWKZZVQtam8t9262BKHcosKYObxirekD6vijSoWO8 ZWoXa+U1oWSFEoOAFDsu6GFqFHFRi5VhqBgIaPEIxrT2MQGHL3KU1bp8CJi/5CTU pNh0wC9SMtnSJJXBIP/nYH81WQxaik3c4eiHFPN4+0McBZQiIaIqMG6x+iiVNvPB MNLLVAzk0QiWeCmSo8OBdjOV0/T+pfQ7lrTCn2B1jdJi1CkAO8m2SwQrG4PpRx8k lUTBd4zTx5DYR+yPF69OyoCQg0XKjW9g62Qo5rmxrQreiidROZOBS1bljWzIPeft otupLmK5kz67n3eB2eto =sB6v -----END PGP SIGNATURE----- Merge tag 'sound-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This became a fairly large pull request.

Devicetree changes for v3.19
Lots of activity in the devicetree code for v3.18. Most of it is related to getting all of the overlay support code in place, but there are other important things in there. There are a few trivial merge conflicts. They shouldn't give you any trouble. Highlights: - OF_RECONFIG notifiers for SPI, I2C and Platform devices. Those subsystems can now respond to live changes to the device tree. - CONFIG_OF_OVERLAY method for applying live changes to the device tree - Removal of the of_allnodes list. This used to be used to iterate over all the nodes in the device tree, but it is unnecessary because the same thing can be done by iterating over the list of child pointers. Getting rid of of_allnodes saves some memory and avoids the possibility of of_allnodes being sorted differently from the child lists. - Support for retrieving original DTB blob via sysfs. Needed by kexec. - More unittests - Documentation and minor bug fixes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJUiaTJAAoJEMWQL496c2LNdKkP/1rk20JXzJc948Z3VFZPXkzf TUKXC+Qn0FmVjQhESkx6LxLDrMDTQlQLlWBmFuWRB87Fk5E32FEf5zzW7I9oQPS4 msIqJoYf5T7EPlmJ/85156xjK5ezc0OyoKEizn23mcKrJE4bmXQEbVw99UUFhq4R Oz1a1ZPQQSSaMteKftOoRBiE3bJut3tJ3dfufNjwOuXi5rALJ0DVxuOeU/Hba13d t05qlImwocKXGBDd/B4psBI5fZl4Tf4AmGOD9aU7YHxrLg4jOCbvqies3DQQ0q3D o9YZBnuBw7A3tzJJ3F5KajRnFLazJBOV5BKGo7eYuTzT56mpZW/HF6eS9b1DbP9x 4q71Vd5qhIuU9JsQAStfZ6pdx3FBXRNGpIXXfwzbCSdaePIuOKS17zvA/Iy5bWeA 2TyqgMuKZwnXOXxQesMZJYIw2IEnIyobzh0A1wAnvReyos/nHF/tha/SA/Jutq1s +0gOkMlPW2EdpADmlfLPRSHgSqO8bfCPeNPihn672MS2dAv9H+XRLcoKuSNErhdl 1gYtnR7IK+Sl0KmMC5YoMvXPchkV5YS2qEp1f3p+ZmgcMSWyHHKMtf8VwjNTaSBU e1AshH6HvmYEPt0cnntSMAxbw+N596QjkVp4RbHsLpyj7qeUVVY56/K/aiM7M69P BvJkuewrhsAxyM2X2OsD =ak0A -----END PGP SIGNATURE----- Merge tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux Pull devicetree changes from Grant Likely: "Lots of activity in the devicetree code for v3.18.

ACPI and power management updates for 3.19-rc1
This time we have some more new material than we used to have during the last couple of development cycles. The most important part of it to me is the introduction of a unified interface for accessing device properties provided by platform firmware. It works with Device Trees and ACPI in a uniform way and drivers using it need not worry about where the properties come from as long as the platform firmware (either DT or ACPI) makes them available. It covers both devices and "bare" device node objects without struct device representation as that turns out to be necessary in some cases. This has been in the works for quite a few months (and development cycles) and has been approved by all of the relevant maintainers. On top of that, some drivers are switched over to the new interface (at25, leds-gpio, gpio_keys_polled) and some additional changes are made to the core GPIO subsystem to allow device drivers to manipulate GPIOs in the "canonical" way on platforms that provide GPIO information in their ACPI tables, but don't assign names to GPIO lines (in which case the driver needs to do that on the basis of what it knows about the device in question). That also has been approved by the GPIO core maintainers and the rfkill driver is now going to use it. Second is support for hardware P-states in the intel_pstate driver. It uses CPUID to detect whether or not the feature is supported by the processor in which case it will be enabled by default. However, it can be disabled entirely from the kernel command line if necessary. Next is support for a platform firmware interface based on ACPI operation regions used by the PMIC (Power Management Integrated Circuit) chips on the Intel Baytrail-T and Baytrail-T-CR platforms. That interface is used for manipulating power resources and for thermal management: sensor temperature reporting, trip point setting and so on. Also the ACPI core is now going to support the _DEP configuration information in a limited way. Basically, _DEP it supposed to reflect off-the-hierarchy dependencies between devices which may be very indirect, like when AML for one device accesses locations in an operation region handled by another device's driver (usually, the device depended on this way is a serial bus or GPIO controller). The support added this time is sufficient to make the ACPI battery driver work on Asus T100A, but it is general enough to be able to cover some other use cases in the future. Finally, we have a new cpufreq driver for the Loongson1B processor. In addition to the above, there are fixes and cleanups all over the place as usual and a traditional ACPICA update to a recent upstream release. As far as the fixes go, the ACPI LPSS (Low-power Subsystem) driver for Intel platforms should be able to handle power management of the DMA engine correctly, the cpufreq-dt driver should interact with the thermal subsystem in a better way and the ACPI backlight driver should handle some more corner cases, among other things. On top of the ACPICA update there are fixes for race conditions in the ACPICA's interrupt handling code which might lead to some random and strange looking failures on some systems. In the cleanups department the most visible part is the series of commits targeted at getting rid of the CONFIG_PM_RUNTIME configuration option. That was triggered by a discussion regarding the generic power domains code during which we realized that trying to support certain combinations of PM config options was painful and not really worth it, because nobody would use them in production anyway. For this reason, we decided to make CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and that lead to the conclusion that the latter became redundant and CONFIG_PM could be used instead of it. The material here makes that replacement in a major part of the tree, but there will be at least one more batch of that in the second part of the merge window. Specifics: - Support for retrieving device properties information from ACPI _DSD device configuration objects and a unified device properties interface for device drivers (and subsystems) on top of that. As stated above, this works with Device Trees and ACPI and allows device drivers to be written in a platform firmware (DT or ACPI) agnostic way. The at25, leds-gpio and gpio_keys_polled drivers are now going to use this new interface and the GPIO subsystem is additionally modified to allow device drivers to assign names to GPIO resources returned by ACPI _CRS objects (in case _DSD is not present or does not provide the expected data). The changes in this set are mostly from Mika Westerberg, Rafael J Wysocki, Aaron Lu, and Darren Hart with some fixes from others (Fabio Estevam, Geert Uytterhoeven). - Support for Hardware Managed Performance States (HWP) as described in Volume 3, section 14.4, of the Intel SDM in the intel_pstate driver. CPUID is used to detect whether or not the feature is supported by the processor. If supported, it will be enabled automatically unless the intel_pstate=no_hwp switch is present in the kernel command line. From Dirk Brandewie. - New Intel Broadwell-H ID for intel_pstate (Dirk Brandewie). - Support for firmware interface based on ACPI operation regions used by the PMIC chips on the Intel Baytrail-T and Baytrail-T-CR platforms for power resource control and thermal management (Aaron Lu). - Limited support for retrieving off-the-hierarchy dependencies between devices from ACPI _DEP device configuration objects and deferred probing support for the ACPI battery driver based on the _DEP information to make that driver work on Asus T100A (Lan Tianyu). - New cpufreq driver for the Loongson1B processor (Kelvin Cheung). - ACPICA update to upstream revision 20141107 which only affects tools (Bob Moore). - Fixes for race conditions in the ACPICA's interrupt handling code and in the ACPI code related to system suspend and resume (Lv Zheng and Rafael J Wysocki). - ACPI core fix for an RCU-related issue in the ioremap() regions management code that slowed down significantly after CPUs had been allowed to enter idle states even if they'd had RCU callbakcs queued and triggered some problems in certain proprietary graphics driver (and elsewhere). The fix replaces synchronize_rcu() in that code with synchronize_rcu_expedited() which makes the issue go away. From Konstantin Khlebnikov. - ACPI LPSS (Low-Power Subsystem) driver fix to handle power management of the DMA engine included into the LPSS correctly. The problem is that the DMA engine doesn't have ACPI PM support of its own and it simply is turned off when the last LPSS device having ACPI PM support goes into D3cold. To work around that, the PM domain used by the ACPI LPSS driver is redesigned so at least one device with ACPI PM support will be on as long as the DMA engine is in use. From Andy Shevchenko. - ACPI backlight driver fix to avoid using it on "Win8-compatible" systems where it doesn't work and where it was used by default by mistake (Aaron Lu). - Assorted minor ACPI core fixes and cleanups from Tomasz Nowicki, Sudeep Holla, Huang Rui, Hanjun Guo, Fabian Frederick, and Ashwin Chaugule (mostly related to the upcoming ARM64 support). - Intel RAPL (Running Average Power Limit) power capping driver fixes and improvements including new processor IDs (Jacob Pan). - Generic power domains modification to power up domains after attaching devices to them to meet the expectations of device drivers and bus types assuming devices to be accessible at probe time (Ulf Hansson). - Preliminary support for controlling device clocks from the generic power domains core code and modifications of the ARM/shmobile platform to use that feature (Ulf Hansson). - Assorted minor fixes and cleanups of the generic power domains core code (Ulf Hansson, Geert Uytterhoeven). - Assorted minor fixes and cleanups of the device clocks control code in the PM core (Geert Uytterhoeven, Grygorii Strashko). - Consolidation of device power management Kconfig options by making CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and removing the latter which is now redundant (Rafael J Wysocki and Kevin Hilman). That is the first batch of the changes needed for this purpose. - Core device runtime power management support code cleanup related to the execution of callbacks (Andrzej Hajda). - cpuidle ARM support improvements (Lorenzo Pieralisi). - cpuidle cleanup related to the CPUIDLE_FLAG_TIME_VALID flag and a new MAINTAINERS entry for ARM Exynos cpuidle (Daniel Lezcano and Bartlomiej Zolnierkiewicz). - New cpufreq driver callback (->ready) to be executed when the cpufreq core is ready to use a given policy object and cpufreq-dt driver modification to use that callback for cooling device registration (Viresh Kumar). - cpufreq core fixes and cleanups (Viresh Kumar, Vince Hsu, James Geboski, Tomeu Vizoso). - Assorted fixes and cleanups in the cpufreq-pcc, intel_pstate, cpufreq-dt, pxa2xx cpufreq drivers (Lenny Szubowicz, Ethan Zhao, Stefan Wahren, Petr Cvek). - OPP (Operating Performance Points) framework modification to allow OPPs to be removed too and update of a few cpufreq drivers (cpufreq-dt, exynos5440, imx6q, cpufreq) to remove OPPs (added during initialization) on driver removal (Viresh Kumar). - Hibernation core fixes and cleanups (Tina Ruchandani and Markus Elfring). - PM Kconfig fix related to CPU power management (Pankaj Dubey). - cpupower tool fix (Prarit Bhargava). / -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJUhj6JAAoJEILEb/54YlRxTM4P/j5g5SfqvY0QKsn7sR7MGZ6v nsgCBhJAqTw3ocNC7EAs8z9h2GWy1KbKpakKYWAh9Fs1yZoey7tFSlcv/Rgjlp70 uU5sDQHtpE9mHKiymdsowiQuWgpl962L4k+k8hUslhlvgk1PvVbpajR6OqG8G+pD asuIW9eh1APNkLyXmRJ3ZPomzs0VmRdZJ0NEs0lKX9mJskqEvxPIwdaxq3iaJq9B Fo0J345zUDcJnxWblDRdHlOigCimglElfN5qJwaC4KpwUKuBvLRKbp4f69+wfT0c kYFiR29X5KjJ2kLfP/wKsLyuDCYYXRq3tCia5M1tAqOjZ+UA89H/GDftx/5lntmv qUlBa35VfdS1SX4HyApZitOHiLgo+It/hl8Z9bJnhyVw66NxmMQ8JYN2imb8Lhqh XCLR7BxLTah82AapLJuQ0ZDHPzZqMPG2veC2vAzRMYzVijict/p4Y2+qBqONltER 4rs9uRVn+hamX33lCLg8BEN8zqlnT3rJFIgGaKjq/wXHAU/zpE9CjOrKMQcAg9+s t51XMNPwypHMAYyGVhEL89ImjXnXxBkLRuquhlmEpvQchIhR+mR3dLsarGn7da44 WPIQJXzcsojXczcwwfqsJCR4I1FTFyQIW+UNh02GkDRgRovQqo+Jk762U7vQwqH+ LBdhvVaS1VW4v+FWXEoZ =5dox -----END PGP SIGNATURE----- Merge tag 'pm+acpi-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "This time we have some more new material than we used to have during the last couple of development cycles.

There was a lot of clean ups and minor fixes. One of those clean ups was
to the trace_seq code. It also removed the return values to the trace_seq_*() functions and use trace_seq_has_overflowed() to see if the buffer filled up or not. This is similar to work being done to the seq_file code as well in another tree. Some of the other goodies include: o Added some "!" (NOT) logic to the tracing filter. o Fixed the frame pointer logic to the x86_64 mcount trampolines o Added the logic for dynamic trampolines on !CONFIG_PREEMPT systems.

kernel: add panic_on_warn
There have been several times where I have had to rebuild a kernel to cause a panic when hitting a WARN() in the code in order to get a crash dump from a system. Sometimes this is easy to do, other times (such as in the case of a remote admin) it is not trivial to send new images to the user. A much easier method would be a switch to change the WARN() over to a panic. This makes debugging easier in that I can now test the actual image the WARN() was seen on and I do not have to engage in remote debugging. This patch adds a panic_on_warn kernel parameter and /proc/sys/kernel/panic_on_warn calls panic() in the warn_slowpath_common() path. The function will still print out the location of the warning. An example of the panic_on_warn output: The first line below is from the WARN_ON() to output the WARN_ON()'s location. After that the panic() output is displayed. WARNING: CPU: 30 PID: 11698 at /home/prarit/dummy_module/dummy-module.c:25 init_dummy+0x1f/0x30 [dummy_module]() Kernel panic - not syncing: panic_on_warn set ...

mm: embed the memcg pointer directly into struct page
Memory cgroups used to have 5 per-page pointers. To allow users to disable that amount of overhead during runtime, those pointers were allocated in a separate array, with a translation layer between them and struct page. There is now only one page pointer remaining: the memcg pointer, that indicates which cgroup the page is associated with when charged. The complexity of runtime allocation and the runtime translation overhead is no longer justified to save that *potential* 0.19% of memory. With CONFIG_SLUB, page->mem_cgroup actually sits in the doubleword padding after the page->private member and doesn't even increase struct page, and then this patch actually saves space. Remaining users that care can still compile their kernels without CONFIG_MEMCG. text data bss dec hex filename 8828345 1725264 983040 11536649 b00909 vmlinux.old 8827425 1725264 966656 11519345 afc571 vmlinux.new [mhocko@suse.cz: update Documentation/cgroups/memory.txt] Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Michal Hocko <mhocko@suse.cz> Acked-by: Vladimir Davydov <vdavydov@parallels.com> Acked-by: David S.

mm: memcontrol: lockless page counters
Memory is internally accounted in bytes, using spinlock-protected 64-bit counters, even though the smallest accounting delta is a page. The counter interface is also convoluted and does too many things. Introduce a new lockless word-sized page counter API, then change all memory accounting over to it. The translation from and to bytes then only happens when interfacing with userspace. The removed locking overhead is noticable when scaling beyond the per-cpu charge caches - on a 4-socket machine with 144-threads, the following test shows the performance differences of 288 memcgs concurrently running a page fault benchmark: vanilla: 18631648.500498 task-clock (msec) # 140.643 CPUs utilized ( +- 0.33% ) 1,380,638 context-switches # 0.074 K/sec ( +- 0.75% ) 24,390 cpu-migrations # 0.001 K/sec ( +- 8.44% ) 1,843,305,768 page-faults # 0.099 M/sec ( +- 0.00% ) 50,134,994,088,218 cycles # 2.691 GHz ( +- 0.33% ) <not supported> stalled-cycles-frontend <not supported> stalled-cycles-backend 8,049,712,224,651 instructions # 0.16 insns per cycle ( +- 0.04% ) 1,586,970,584,979 branches # 85.176 M/sec ( +- 0.05% ) 1,724,989,949 branch-misses # 0.11% of all branches ( +- 0.48% ) 132.474343877 seconds time elapsed ( +- 0.21% ) lockless: 12195979.037525 task-clock (msec) # 133.480 CPUs utilized ( +- 0.18% ) 832,850 context-switches # 0.068 K/sec ( +- 0.54% ) 15,624 cpu-migrations # 0.001 K/sec ( +- 10.17% ) 1,843,304,774 page-faults # 0.151 M/sec ( +- 0.00% ) 32,811,216,801,141 cycles # 2.690 GHz ( +- 0.18% ) <not supported> stalled-cycles-frontend <not supported> stalled-cycles-backend 9,999,265,091,727 instructions # 0.30 insns per cycle ( +- 0.10% ) 2,076,759,325,203 branches # 170.282 M/sec ( +- 0.12% ) 1,656,917,214 branch-misses # 0.08% of all branches ( +- 0.55% ) 91.369330729 seconds time elapsed ( +- 0.45% ) On top of improved scalability, this also gets rid of the icky long long types in the very heart of memcg, which is great for 32 bit and also makes the code a lot more readable. Notable differences between the old and new API: - res_counter_charge() and res_counter_charge_nofail() become page_counter_try_charge() and page_counter_charge() resp. to match the more common kernel naming scheme of try_do()/do() - res_counter_uncharge_until() is only ever used to cancel a local counter and never to uncharge bigger segments of a hierarchy, so it's replaced by the simpler page_counter_cancel() - res_counter_set_limit() is replaced by page_counter_limit(), which expects its callers to serialize against themselves - res_counter_memparse_write_strategy() is replaced by page_counter_limit(), which rounds down to the nearest page size - rather than up. This is more reasonable for explicitely requested hard upper limits. - to keep charging light-weight, page_counter_try_charge() charges speculatively, only to roll back if the result exceeds the limit. Because of this, a failing bigger charge can temporarily lock out smaller charges that would otherwise succeed. The error is bounded to the difference between the smallest and the biggest possible charge size, so for memcg, this means that a failing THP charge can send base page charges into reclaim upto 2MB (4MB) before the limit would have been reached. This should be acceptable.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull VFS changes from Al Viro: "First pile out of several (there _definitely_ will be more). Stuff in this one: - unification of d_splice_alias()/d_materialize_unique() - iov_iter rewrite - killing a bunch of ->f_path.dentry users (and f_dentry macro).

Merge branch 'irq-irqdomain-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq domain updates from Thomas Gleixner: "The real interesting irq updates: - Support for hierarchical irq domains: For complex interrupt routing scenarios where more than one interrupt related chip is involved we had no proper representation in the generic interrupt infrastructure so far. That made people implement rather ugly constructs in their nested irq chip implementations. The main offenders are x86 and arm/gic. To distangle that mess we have now hierarchical irqdomains which seperate the various interrupt chips and connect them via the hierarchical domains. That keeps the domain specific details internal to the particular hierarchy level and removes the criss/cross referencing of chip internals. The resulting hierarchy for a complex x86 system will look like this: vector mapped: 74 msi-0 mapped: 2 dmar-ir-1 mapped: 69 ioapic-1 mapped: 4 ioapic-0 mapped: 20 pci-msi-2 mapped: 45 dmar-ir-0 mapped: 3 ioapic-2 mapped: 1 pci-msi-1 mapped: 2 htirq mapped: 0 Neither ioapic nor pci-msi know about the dmar interrupt remapping between themself and the vector domain. If interrupt remapping is disabled ioapic and pci-msi become direct childs of the vector domain. In hindsight we should have done that years ago, but in hindsight we always know better :) - Support for generic MSI interrupt domain handling We have more and more non PCI related MSI interrupts, so providing a generic infrastructure for this is better than having all affected architectures implementing their own private hacks. - Support for PCI-MSI interrupt domain handling, based on the generic MSI support. This part carries the pci/msi branch from Bjorn Helgaas pci tree to avoid a massive conflict. The PCI/MSI parts are acked by Bjorn. I have two more branches on top of this.

asm-generic: asm/io.h rewrite
While there normally is no reason to have a pull request for asm-generic but have all changes get merged through whichever tree needs them, I do have a series for 3.19. There are two sets of patches that change significant portions of asm/io.h, and this branch contains both in order to resolve the conflicts: - Will Deacon has done a set of patches to ensure that all architectures define {read,write}{b,w,l,q}_relaxed() functions or get them by including asm-generic/io.h. These functions are commonly used on ARM specific drivers to avoid expensive L2 cache synchronization implied by the normal {read,write}{b,w,l,q}, but we need to define them on all architectures in order to share the drivers across architectures and to enable CONFIG_COMPILE_TEST configurations for them - Thierry Reding has done an unrelated set of patches that extends the asm-generic/io.h file to the degree necessary to make it useful on ARM64 and potentially other architectures. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVIdwNmCrR//JCVInAQJWuw/9FHt2ThMnI1J1Jqy4CVwtyjWTSa6Y/uVj xSytS7AOvmU/nw1quSoba5mN9fcUQUtK9kqjqNcq71WsQcDE6BF9SFpi9cWtjWcI ZfWsC+5kqry/mbnuHefENipem9RqBrLbOBJ3LARf5M8rZJuTz1KbdZs9r9+1QsCX ou8jeqVvNKUn9J1WyekJBFSrPOtZ4bCUpeyh23JHRfPtJeAHNOuPuymj6WceAz98 uMV1icRaCBMySsf9HgsHRYW5HwuCm3MrrYj6ukyPpgxYz7FRq4hJLDs6GnlFtAGb 71g87NpFdB32qbW+y1ntfYaJyUryMHMVHBWcV5H9m0btdHTRHYZjoOGOPuyLHHO8 +l4/FaOQhnDL8cNDj0HKfhdlyaFylcWgs1wzj68nv31c1dGjcJcQiyCDwry9mJhr erh4EewcerUvWzbBMQ4JP1f8syKMsKwbo1bVU61a1RQJxEqVCzJMLweGSOFmqMX2 6E4ZJVWv81UFLoFTzYx+7+M45K4NWywKNQdzwKmqKHc4OQyvq4ALJI0A7SGFJdDR HJ7VqDiLaSdBitgJcJUxNzKcyXij6wE9jE1fBe3YDFE4LrnZXFVLN+MX6hs7AIFJ vJM1UpxRxQUMGIH2m7rbDNazOAsvQGxINOjNor23cNLuf6qLY1LrpHVPQDAfJVvA 6tROM77bwIQ= =xUv6 -----END PGP SIGNATURE----- Merge tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic asm/io.h rewrite from Arnd Bergmann: "While there normally is no reason to have a pull request for asm-generic but have all changes get merged through whichever tree needs them, I do have a series for 3.19.

John W. Linville says: ==================== pull request: wireless-next 2014-12-08 Please pull this last batch of pending wireless updates for the 3.19 tree... For the wireless bits, Johannes says: "This time I have Felix's no-status rate control work, which will allow drivers to work better with rate control even if they don't have perfect status reporting. In addition to this, a small hwsim fix from Patrik, one of the regulatory patches from Arik, and a number of cleanups and fixes I did myself. Of note is a patch where I disable CFG80211_WEXT so that compatibility is no longer selectable - this is intended as a wake-up call for anyone who's still using it, and is still easily worked around (it's a one-line patch) before we fully remove the code as well in the future." For the Bluetooth bits, Johan says: "Here's one more bluetooth-next pull request for 3.19: - Minor cleanups for ieee802154 & mac802154 - Fix for the kernel warning with !TASK_RUNNING reported by Kirill A. Shutemov - Support for another ath3k device - Fix for tracking link key based security level - Device tree bindings for btmrvl + a state update fix - Fix for wrong ACL flags on LE links" And... "In addition to the previous one this contains two more cleanups to mac802154 as well as support for some new HCI features from the Bluetooth 4.2 specification. From the original request: 'Here's what should be the last bluetooth-next pull request for 3.19. It's rather large but the majority of it is the Low Energy Secure Connections feature that's part of the Bluetooth 4.2 specification. The specification went public only this week so we couldn't publish the corresponding code before that. The code itself can nevertheless be considered fairly mature as it's been in development for over 6 months and gone through several interoperability test events. Besides LE SC the pull request contains an important fix for command complete events for mgmt sockets which also fixes some leaks of hci_conn objects when powering off or unplugging Bluetooth adapters. A smaller feature that's part of the pull request is service discovery support. This is like normal device discovery except that devices not matching specific UUIDs or strong enough RSSI are filtered out. Other changes that the pull request contains are firmware dump support to the btmrvl driver, firmware download support for Broadcom BCM20702A0 variants, as well as some coding style cleanups in 6lowpan & ieee802154/mac802154 code.'" For the NFC bits, Samuel says: "With this one we get: - NFC digital improvements for DEP support: Chaining, NACK and ATN support added. - NCI improvements: Support for p2p target, SE IO operand addition, SE operands extensions to support proprietary implementations, and a few fixes. - NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support, and SE IO operand addition. - A bunch of minor improvements and fixes for STMicro st21nfcb and st21nfca" For the iwlwifi bits, Emmanuel says: "Major works are CSA and TDLS. On top of that I have a new firmware API for scan and a few rate control improvements. Johannes find a few tricks to improve our CPU utilization and adds support for a new spin of 7265 called 7265D. Along with this a few random things that don't stand out." And... "I deprecate here -8.ucode since -9 has been published long ago. Along with that I have a new activity, we have now better a infrastructure for firmware debugging. This will allow to have configurable probes insides the firmware. Luca continues his work on NetDetect, this feature is now complete. All the rest is minor fixes here and there." For the Atheros bits, Kalle says: "Only ath10k changes this time and no major changes. Most visible are: o new debugfs interface for runtime firmware debugging (Yanbo) o fix shared WEP (Sujith) o don't rebuild whenever kernel version changes (Johannes) o lots of refactoring to make it easier to add new hw support (Michal) There's also smaller fixes and improvements with no point of listing here." In addition, there are a few last minute updates to ath5k, ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210. Also included is a pull of the wireless tree to pick-up the fixes originally included in "pull request: wireless 2014-12-03"... Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

ARM: SoC DT updates for 3.19
The DT branch adds a lot of new stuff for additional SoC and board support. The branch is the largest one and contains 513 out of the total 972 non-merge arm-soc changesets for 3.19. Most of the changes are about enabling additional on-chip devices for existing machines, but there are also an unusual number of new SoC types being added this time: * AMLogic Meson8 * ARM Realview in DT mode * Allwinner A80 * Broadcom BCM47081 * Broadcom Cygnus * Freescale LS1021A * Freescale Vybrid 500 series * Mediatek MT6592, MT8127, MT8135 * STMicroelectronics STiH410 * Samsung Exynos4415 The level of support for the above differs widely, some are just stubs with nothing more than CPU, memory and a UART, but others are fairly complete. As usual, these get extended over time. There are also many new boards getting added, this is the list of model strings that are showing up in new dts files: * ARM RealView PB1176 * Altera SOCFPGA Arria 10 * Asus RT-N18U (BCM47081) * Buffalo WZR-1750DHP (BCM4708) * Buffalo WZR-600DHP2 (BCM47081) * Cygnus Enterprise Phone (BCM911360_ENTPHN) * D-Link DIR-665 * Google Spring * IGEP COM MODULE Rev.

There are also many new boards getting added, this is the list of model strings that are showing up in new dts files: - ARM RealView PB1176 - Altera SOCFPGA Arria 10 - Asus RT-N18U (BCM47081) - Buffalo WZR-1750DHP (BCM4708) - Buffalo WZR-600DHP2 (BCM47081) - Cygnus Enterprise Phone (BCM911360_ENTPHN) - D-Link DIR-665 - Google Spring - IGEP COM MODULE Rev.

ARM: SoC driver updates for 3.19
These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree. The largest single change here this time around is the Tegra iommu/memory controller driver, which gets updated to the new iommu DT binding. More drivers like this are likely to follow for the following merge window, but we should be able to do those through the iommu maintainer. Other notable changes are: * reset controller drivers from the reset maintainer (socfpga, sti, berlin) * fixes for the keystone navigator driver merged last time * at91 rtc driver changes related to the at91 cleanups * ARM perf driver changes from Will Deacon * updates for the brcmstb_gisb driver -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVIcj4mCrR//JCVInAQIvWg//WD72+2q0RmEvu8r/YN4SDfg5iY7OMzgy Jyt6rN1IhXBY5GJL5Hil1q2JP/7o8vypekllohmBYWzXO3ZJ2VK6NPIXEMuzaiCz D9gmb+N6FdR2L2iYPv7B/3uOf55pHjBu525+vLspCTOgcWBrLgCnA9e9Yg462AEf VP3x+kV0AH25lovEi3mPrc2e46jnl0Mzp3f3PCkPqRSEMn7sxu9ipii+elxvArYp jYYCB03ZEBFa7T0e4HD38gnVLbC6dTj47AcSCWYP9WhxJ2RmCQKRBEnJre02hgar NPg8z+OrUACIAkvJHzg3WccmXdi0aqQ2JDsl46Tkl7pA6NdyMLfizT3OiZnMRmgc 34H0ZSxclW+j25aI8OmDpv2ypZev+UAzkbRobcvF+aV/zJeAX88tPgcshfCUVZll ZIqO7oJB73nCl1XBLv2ZrLV2tcOox6jL/5LQt0WYA5Szg5upo7D1fZl8v5jXX7eJ C62ychuABs6hsmH5jEy+73kdpHbYft7dZfGZxdgq1AIOkdWoynCze/R7Vj24xoXR 118cTNN9ZTPHmN5yxUvuGoqA3FWOqkJXaTS4W0hRD6OxOGTsTV4FIlRnD+K7feOW ng1yfIcvKR1Dx7tsySTHQK+bZGNnovA/ENPK6VDuhbwE62Lx7N5hcbsSIKKwRI9C D1m1fC+AIcQ= =MwMG -----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 updates from Arnd Bergmann: "These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree.
