- Some refactoring, cleanups and small improvements from Sjur Brændeland. The improvements are mainly about better supporting varios virtio properties (such as virtio's config space, status and features). I now see that I messed up while commiting one of Sjur's patches and erroneously put myself as the author, as well as letting a nasty typo sneak in. I will not fix this in order to avoid rebasing the patches.

ARM: late Exynos multiplatform changes
These continue the multiplatform support for exynos, adding support for building most of the essential drivers (clocksource, clk, irqchip) when combined with other platforms. As a result, it should become really easy to add full multiplatform exynos support in 3.11, although we don't yet enable it for 3.10. The changes were not included in the earlier multiplatform series in order to avoid clashes with the other Exynos updates. This also includes work from Tomasz Figa to fix the pwm clocksource code on Exynos, which is not strictly required for multiplatform, but related to the other patches in this set and needed as a bug fix for at least one board. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUYgmgWCrR//JCVInAQIp6A//cb87A7biCHo0hd64v7RtX2dIvYTc8ZDh 7O9yH7NuAtbSI7FF7cVQGGK6nCRqmwO2SM/KLFgbt2MF36FLgQKKZhJIDM/qB4jb 3DCHHH814eqExf4MFfZL4Yxl4FaMqxzSwYX8fD28GmpeVxLeHjh0yQCKmPejz5MW WgkMcBJS3IPqbhhKMcMZmXteLrEzEm43Uj6dxkZP7RbinyuWzHvx3IWWv4gQ6ITz 3jcCvZC5JWBo9MEPH43vlmOd8qsAn0OvkbtbYiy2Tre5VerqOgbEEXU2U0A2zUSj YTmRvwIGsIylL2EkVsJTkMj8KJ8TAHZjHyNUY8m2UzWuS+9EdZjf6rXeKIdUz9Wa 0dmiWJEOEvejk0RnHEJm7anmKp7a9YHFkFSRnHbLOAXAMkUZWWcVAMZ4UbDK8RtF RX6R+ga9tR8R7aBLIzqYyfSHaZ7xUpF6nSBOM4GNVNKtViJv3PENWVQrm2GHcQ9w +4IMUqXO/5IRvuHW93l+oN8tENDTF0cR0+S7t0R6Vuuh7OebRt9TAE421Hrvt+7p gI5tvhEeV3o1CMmXWod8X1jxY/1OrONG7wX/x07ymiRnXSd+sZ0CPkYyWultKNw8 bCAsnOP2aFpO1RB0XEC5y8FZ5uSfcQ7Ngu2kyAP7mEXV6qbSHgmb+lyxf2G8ftL2 Rn0M7nbLcz4= =FY7+ -----END PGP SIGNATURE----- Merge tag 'multiplatform-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull late ARM Exynos multiplatform changes from Arnd Bergmann: "These continue the multiplatform support for exynos, adding support for building most of the essential drivers (clocksource, clk, irqchip) when combined with other platforms.

ARM: arm-soc: late cleanups
These are cleanups and smaller changes that either depend on earlier feature branches or came in late during the development cycle. We normally try to get all cleanups early, so these are the exceptions: - A follow-up on the clocksource reworks, hopefully the last time we need to merge clocksource subsystem changes through arm-soc. A first set of patches was part of the original 3.10 arm-soc cleanup series because of interdependencies with timer drivers now moved out of arch/arm. - Migrating the SPEAr13xx platform away from using auxdata for DMA channel descriptions towards using information in device tree, based on the earlier SPEAr multiplatform series - A few follow-ups on the Atmel SAMA5 support and other changes for Atmel at91 based on the larger at91 reworks. - Moving the armada irqchip implementation to drivers/irqchip - Several OMAP cleanups following up on the larger series already merged in 3.10. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUYj5U2CrR//JCVInAQLNIRAAvsCtYOmXTxkRBxdtNEUUbkEjx71Se7q0 h9PR8vqlkbYwONkJ8a6j8pKq/WJDmLpHQWg/moBsvlGc6uEVBPBFhCWHs1+yGUzX GhnJOaIKh3+651hIoXccS+/YZ16e1EAzdCM7+1QegPTldsRGkTOiwXgmR51kmPrz 6cZ8P5MFqMrWIy4XqWhOBbMDCY/An05IHMpniGIamUg2/uB921Z0wNFvDrnsg97u DsVEwimyCJ0j7aO4TH+fkvsjoGWnIhxPtpaIm8iff6TPRI49deRb3zYpnIONm+oG /cQrRf3BNW+aiTuRCTEjdBNGtcrYgN6CLWWjzgMhv1itSlX8swBcOhuNJRCGNQRI v3wL4aEBxUpPGGL8erc2GIW7pe29YC2UEYI2z1X/5MEzYO589zkkG2k+/3HQVUwp dnYpQxhjRMvh4mcodBJFRjzH1Z7agKUwtoKalAHRRH7r5gJDkpL3zLoMhYPTG5IZ OwU+aYf+dDxh2kKW0zs8a/qL97UTHjlTRUC9LPoumvJ7LlKeDfzEn7DHUm2gggiu dO9ye/NF/xEXoDXTl0Qp2wJ6/sbPSLyCYCIMdP/gJjWUiDDqqZ0VRaKL7vE/JWrd NJ7k5yunX8/kRgfqgRFLDdFnPj1JeYHlmexsq4l9TPbPstoIcbw8u1v9sr8aZF+Z agh9u4e7QU8= =HWfp -----END PGP SIGNATURE----- Merge tag 'cleanup-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC late cleanups from Arnd Bergmann: "These are cleanups and smaller changes that either depend on earlier feature branches or came in late during the development cycle.

ARM: arm-soc platform updates for 3.10, part 3
This is the third and smallest of the SoC specific updates. Changes include: * SMP support for the Xilinx zynq platform * Smaller imx changes * LPAE support for mvebu * Moving the orion5x, kirkwood, dove and mvebu platforms to a common "mbus" driver for their internal devices. It would be good to get feedback on the location of the "mbus" driver. Since this is used on multiple platforms may potentially get shared with other architectures (powerpc and arm64), it was moved to drivers/bus/. We expect other similar drivers to get moved to the same place in order to avoid creating more top-level directories under drivers/ or cluttering up the messy drivers/misc/ even more. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUYgifmCrR//JCVInAQLZ6A//VD38ocUx9RPC8rOgrkzQxcMTh3wFghoA BVvS8fcAmhZYA5+GpTYBm+5XH2Jvu6Pv0hrba8TOeEhyZJxiWA6vg0cWWmnvZLDC Q0uubhqIhv32I2Oq4uJb/VyzcCrQFrnjhw9HHphy7YlGKKBUFWrbgTaOypwbgXr9 DnB7u04DvaKcUjZb4Y0HaUDM7qWMFDPbKKF5WMZPqjocnjsiBQ2JMw+2KByliWR3 mCI+FdickpDYSVp9V9iRM6F73cItknjZIzQs1RYg/GSuPSWkWTdfzE1Blk/561Fo QDrNDhnXHlt+bmQRKGWel2gDWBZW47Wj+XkjGpWDFh+e/l3vNJq0hrzXizuRCLSw /2VefXyd3jNj8UWL3+GCA4dnw8fx14dgfNJ2iu7kg6l4ggwpJ05ToxabkLFlTRwy LloDFjswiTBi75YdQRQCV/95NIxvIQIkbytPrk5zQWVwg8ZXoicgzRRUL5gifLh+ WE+zaY/A5e1fXN/XS70hvbp2ROZtfGOdunUR9XFR8KNqDoJDlqtrlV3Pjh75YY8G JUmCKQjzfubr5WHskPBGCtsSb1455MEIFVANEtlJyOEKp6ytXfpVvrrZtAvmD6Ep 07dOqOgflnuZPk7H0JOf7mTf9L+fmNp4ubjRqcs9ZfPsEGoQFqBtpLF6JQbxUYGd j69lW3jEM3o= =rQsu -----END PGP SIGNATURE----- Merge tag 'soc-for-linus-3' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates (part 3) from Arnd Bergmann: "This is the third and smallest of the SoC specific updates.

ARM: arm-soc platform updates for 3.10, part 2
These patches are all for Renesas shmobile, and depend on the earlier pinctrl updates. Remarkably, this adds support for three new SoCs: r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is for pinctrl (using the new subsystem) and for clocks (not yet using the common clock subsystem). The latter will have to get converted in one of the upcoming releases, but shmobile is not ready for that yet. The series also contains Renesas shmobile board changes, adding one board file for each of the three new SoCs. These boards are using a mix of classic and device-tree based probing, as there is still a lot of infrastructure in shmobile that has not been converted to DT yet. Once those are resolved to the degree that no board specific setup code is needed, they can get folded into the respective SoC setup files. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUYghoGCrR//JCVInAQIS0hAAoTaH/IgTmKMsKuP1fS/zhsXNSioO77GR 5KnEigaprC7JJK4k+Ahl6xVY/6/RmjWA3aLJ6eqBHHsupE1c5AOgDxIB78PtY8gn vS+oKPqUlYi9bMJRp6LDsr23filt1Ri6woVYnW7htFsfXZIqxf+x6OlMKGULC4Zv 469rx/mgUB7IH/uwp8Jasr7xtE4hnjtgoUIqAKRmE10dLUTAuCN5+SABhlKMZIbl W5VimdiDK6pNm2ENPcJQhTCMK1pFuChgrzpqOGSxsAiYIQgshuAuJJLb0RvEMppu zuDQIxjfmJrwzytyGpxC4c9YVhNajppnWuenpAyaqaPuAi5sGkNFzdJ5NNWokZZ7 g6PfKLr9SAnuvfpTTX/JVuVYHysj18wEGVlLklLFDX8l9Bt6RZ17DARZ+4P8RLgN 0NI5j/IWwCesrsbS000NT7vi+mK/cWW22Z7oXa8aIQYPDod2aV5SxImmfXWx0xvf vDOkzeNxJb5Tpp6WN1A715ZYdWfEuCJT3D6jX5Gsv6Ggri0+zwbsm/NglCCcqe0X slO/74Kn9nknK85p5rm51KIaHvP4POPR/pZP9mQvDDKIqs3qQSjhBgozk0gWbara Wg6k2yeRPxmdj+tsGQMxmT2iLWCWx/uhAilW83oOUiFtTPnC6HkBF5AdXXI08Yt8 /d19O715i/g= =xaLf -----END PGP SIGNATURE----- Merge tag 'soc-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates (part 2) from Arnd Bergmann: "These patches are all for Renesas shmobile, and depend on the earlier pinctrl updates.

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.

Btrfs: rescan for qgroups
If qgroup tracking is out of sync, a rescan operation can be started. It iterates the complete extent tree and recalculates all qgroup tracking data. This is an expensive operation and should not be used unless required. A filesystem under rescan can still be umounted. The rescan continues on the next mount.

Btrfs: allow omitting stream header and end-cmd for btrfs send
Two new flags are added to allow omitting the stream header and the end command for btrfs send streams. This is used in cases where you send multiple snapshots back-to-back in one stream. This used to be encoded like this (with 2 snapshots in this example): <stream header> + <sequence of commands> + <end cmd> + <stream header> + <sequence of commands> + <end cmd> + EOF The new format (if the two new flags are used) is this one: <stream header> + <sequence of commands> + <sequence of commands> + <end cmd> Note that the currently existing receivers treat <end cmd> only as an indication that a new <stream header> is following. This means, you can just skip the sequence <end cmd> <stream header> without loosing compatibility. As long as an EOF is following, the currently existing receivers handle the new format (if the two new flags are used) exactly as the old one. So what is the benefit of this change? The goal is to be able to use a single stream (one TCP connection) to multiplex a request/response handshake plus Btrfs send streams, all in the same stream. In this case you cannot evaluate an EOF condition as an end of the Btrfs send stream. You need something else, and the <end cmd> is just perfect for this purpose. The summary is: The format change is driven by the need to send several Btrfs send streams over a single TCP connections, with the ability for a repeated request/response handshake in the middle. And this format change does not break any existing tool, it is completely compatible. You could compare the old behaviour of the Btrfs send stream to the one of ftp where you need a seperate request/response channel and newly opened data transfer channels for each file, while the new behaviour is more like http using a single stream for everything.

net: frag, fix race conditions in LRU list maintenance
This patch fixes race between inet_frag_lru_move() and inet_frag_lru_add() which was introduced in commit 3ef0eb0db4bf92c6d2510fe5c4dc51852746f206 ("net: frag, move LRU list maintenance outside of rwlock") One cpu already added new fragment queue into hash but not into LRU. Other cpu found it in hash and tries to move it to the end of LRU. This leads to NULL pointer dereference inside of list_move_tail(). Another possible race condition is between inet_frag_lru_move() and inet_frag_lru_del(): move can happens after deletion.

HID: debug: fix RCU preemption issue
Commit 2353f2bea ("HID: protect hid_debug_list") introduced mutex locking around debug_list access to prevent SMP races when debugfs nodes are being operated upon by multiple userspace processess. mutex is not a proper synchronization primitive though, as the hid-debug callbacks are being called from atomic contexts. We also have to be careful about disabling IRQs when taking the lock to prevent deadlock against IRQ handlers. Benjamin reports this has also been reported in RH bugzilla as bug #958935. =============================== [ INFO: suspicious RCU usage. ] 3.9.0+ #94 Not tainted ------------------------------- include/linux/rcupdate.h:476 Illegal context switch in RCU read-side critical section! other info that might help us debug this: rcu_scheduler_active = 1, debug_locks = 0 4 locks held by Xorg/5502: #0: (&evdev->mutex){+.+...}, at: [<ffffffff81512c3d>] evdev_write+0x6d/0x160 #1: (&(&dev->event_lock)->rlock#2){-.-...}, at: [<ffffffff8150dd9b>] input_inject_event+0x5b/0x230 #2: (rcu_read_lock){.+.+..}, at: [<ffffffff8150dd82>] input_inject_event+0x42/0x230 #3: (&(&usbhid->lock)->rlock){-.....}, at: [<ffffffff81565289>] usb_hidinput_input_event+0x89/0x120 stack backtrace: CPU: 0 PID: 5502 Comm: Xorg Not tainted 3.9.0+ #94 Hardware name: Dell Inc.

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.

fs: Fix hang with BSD accounting on frozen filesystem
When BSD process accounting is enabled and logs information to a filesystem which gets frozen, system easily becomes unusable because each attempt to account process information blocks. Thus e.g. every task gets blocked in exit. It seems better to drop accounting information (which can already happen when filesystem is running out of space) instead of locking system up. So we just skip the write if the filesystem is frozen.

sched: Keep at least 1 tick per second for active dynticks tasks
The scheduler doesn't yet fully support environments with a single task running without a periodic tick. In order to ensure we still maintain the duties of scheduler_tick(), keep at least 1 tick per second. This makes sure that we keep the progression of various scheduler accounting and background maintainance even with a very low granularity. Examples include cpu load, sched average, CFS entity vruntime, avenrun and events such as load balancing, amongst other details handled in sched_class::task_tick(). This limitation will be removed in the future once we get these individual items to work in full dynticks CPUs.

sound updates for v3.10-rc1
Mostly many small changes spread as seen in diffstat in sound/* directory by this update. A significant change in the subsystem level is the introduction of snd_soc_component, which will help more generic handling of SoC and off-SoC components. Also, snd_BUG_ON() macro is enabled unconditionally now due to its misuses, so people might hit kernel warnings (it's a good thing for us). - compress-offload: support for capture by Charles Keepax - HD-audio: codec delay support by Dylan Reid - HD-audio: improvements/fixes in generic parser: better headphone mic and headset mic support, jack_modes hint consolidation, proper beep attach/detachment, generalized power filter controls by David Henningsson, et al - HD-audio: Improved management of HDMI codec pins/converters - HD-audio: Better pin/DAC assignment for VIA codecs - HD-audio: Haswell HDMI workarounds - HD-audio: ALC268 codec support, a few new quirks for Chromebooks - USB: regression fixes: USB-MIDI autopm fix, the recent ISO latency fix by Clemens Ladisch - USB: support for DSD formats by Daniel Mack - USB: A few UAC2 device endian/cock fixes by Eldad Zack - USB: quirks for Emu 192kHz support, Novation Twitch DJ controller, Yamaha THRxx devices - HDSPM: updates for TCO controls by Adrian Knoth - ASoC: Add a snd_soc_component object type for generic handling of SoC and off-SoC components by Kuninori Morimoto, - dmaengine: a large set of cleanups and conversions by Lars-Peter Clausen - ASoC DAPM: performance optimizations from Ryo Tsutsui - ASoC DAPM: support for mixer control sharing by Stephen Warren - ASoC: multiplatform ARM cleanups from Arnd Bergmann - ASoC: new codec drivers for AK5385 and TAS5086 from Daniel Mack -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIcBAABAgAGBQJRg2bUAAoJEGwxgFQ9KSmksasQAIq1ypbylrLA3vf7PUXmL7Jb hMtC5tzasZqJsIZ2fyhiZL8J5yQ78Z5dhjehFWlCbJEaKhsjZVyb67RpuK597b6K Ypa30OghbWuCoKjmaXK9AFTuijTxdefmewIJfgwVMYtgA5rBU70qt96NC/b/UQXk gEPI740i7EFJL2wfcqRpGoKGO1o80yMuKzIj3gHUZMFHYYhPgvVuGt9cCe3cXwLV IBT77PjMoGt1Q7iJQkX4DGlB5n526l1G8a6VptdCou0qyEWfhgSik5I3msNuAXte 1KYE4zj0Rq4xqN28/D/eAF1o3q+X9aiLttGpG0sJLiwGagdWVFaXLyJDMhZxCbwz 1F4k+B8UCucojw3HtNzoIQJezoRX2aHMjlAZ50b416hITkg5VQe5+sJBxpjIJo4I GSmizUiNahDk9jtI/PEGo7yr8CdRTY3v38mdZRGYxyWgJ1a8sNwQwqUdH6A0D/w6 3wMp4Y9Zt8AK/kiWLLWvsDVvwRptqplrXistTvv4v2xVJgvU+klDsDpa5Lz7kG7Z q43RA4o+yWdG6d1hTgMXp7FGwUkcer7WKWEmAZsQmX03Q0zjZqMhfUwVUtaHIx9c 6YipHdVMAJ0sz/dYrKnZ92hbZcXNj/A9zfqYWeFlA/18FCO6u4BXODBup8BLwyUm hfOv+M/q6haNA98GDHS9 =sYiI -----END PGP SIGNATURE----- Merge tag 'sound-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "Mostly many small changes spread as seen in diffstat in sound/* directory by this update.
