Pull MMC updates from Ulf Hansson: "There are two major achievements for MMC in this release, which deserves to be specially highlighted. First, we have converted the MMC block device from using the legacy blk interface into using the modern blkmq interface. Not only do we get all the nice effects from using blkmq, but it also means that new fresh nice code replaces old rusty code. Great news to everybody that cares about MMC/SD! It should also be noted that converting to blkmq has not been trivial, mostly because of that we have been carrying too much of MMC specific optimizations for the I/O request path, rather than striving to move these to the generic blk layer. Hopefully we won't be doing that mistake, ever again. Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro), who both have been working on this for quite some time! Second, on top of the blkmq deployment, we have enabled full support the eMMC command queuing feature, introduced in the eMMC v.5.1 spec. This also includes an implementation of a host driver library, supporting the corresponding CQHCI HW. Ideally, those controllers that supports CQHCI should only need some minor adaptations to make this play. So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan driver used on Rockchip RK3399, have enabled support for eMMC command queueing. Worth to highlight is also that, implementing the eMMC command queuing support has been a collaborative effort, as several people from Codeaurora, Rockchip, Intel and Linaro have been involved. However, the work has been driven by Adrian Hunter (Intel). In some shadow of the above, here are the rest of the highlights: MMC core: - Don't remove non-removable cards during system suspend - Add a slot-gpio helper to check capability of GPIO WP detection MMC host: - sdhci: Cleanups and improvements of some wakeup related code - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400 - sdhci_f_sdh30: Add ACPI support - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume - sdhci-of-esdhc: A few minor fixes - mmci: Add support for new STM32 variant - renesas_sdhi: enable R-Car D3 (r8a77995) support - tmio/renesas_sdhi: Re-structuring, cleanups and modernizations" * tag 'mmc-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: (96 commits) mmc: mmci: fix error return code in mmci_probe() mmc: davinci: suppress error message on EPROBE_DEFER mmc: davinci: dont' use module_platform_driver_probe() mmc: tmio: hide unused tmio_mmc_clk_disable/tmio_mmc_clk_enable functions mmc: mmci: Add STM32 variant mmc: mmci: Add support for setting pad type via pinctrl mmc: mmci: Don't pretend all variants to have OPENDRAIN bit mmc: mmci: Don't pretend all variants to have MCI_STARBITERR flag mmc: mmci: Don't pretend all variants to have MMCIMASK1 register mmc: tmio: refactor .get_ro hook mmc: slot-gpio: add a helper to check capability of GPIO WP detection mmc: tmio: remove dma_ops from tmio_mmc_host_probe() argument mmc: tmio: move {tmio_}mmc_of_parse() to tmio_mmc_host_alloc() mmc: tmio: move clk_enable/disable out of tmio_mmc_host_probe() mmc: tmio: ioremap memory resource in tmio_mmc_host_alloc() mmc: sh_mmcif: remove redundant initialization of 'opc' mmc: sdhci: Rework sdhci_enable_irq_wakeups() mmc: sdhci: Handle failure of enable_irq_wake() mmc: sdhci: Stop exporting sdhci_enable_irq_wakeups() mmc: sdhci-pci: Use device wakeup capability to determine MMC_PM_WAKE_SDIO_IRQ capability ...

Pull power management updates from Rafael Wysocki: "This includes some infrastructure changes in the PM core, mostly related to integration between runtime PM and system-wide suspend and hibernation, plus some driver changes depending on them and fixes for issues in that area which have become quite apparent recently. Also included are changes making more x86-based systems use the Low Power Sleep S0 _DSM interface by default, which turned out to be necessary to handle power button wakeups from suspend-to-idle on Surface Pro3. On the cpufreq front we have fixes and cleanups in the core, some new hardware support, driver updates and the removal of some unused code from the CPU cooling thermal driver. Apart from this, the Operating Performance Points (OPP) framework is prepared to be used with power domains in the future and there is a usual bunch of assorted fixes and cleanups. Specifics: - Define a PM driver flag allowing drivers to request that their devices be left in suspend after system-wide transitions to the working state if possible and add support for it to the PCI bus type and the ACPI PM domain (Rafael Wysocki). - Make the PM core carry out optimizations for devices with driver PM flags set in some cases and make a few drivers set those flags (Rafael Wysocki). - Fix and clean up wrapper routines allowing runtime PM device callbacks to be re-used for system-wide PM, change the generic power domains (genpd) framework to stop using those routines incorrectly and fix up a driver depending on that behavior of genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven). - Fix and clean up the PM core's device wakeup framework and re-factor system-wide PM core code related to device wakeup (Rafael Wysocki, Ulf Hansson, Brian Norris). - Make more x86-based systems use the Low Power Sleep S0 _DSM interface by default (to fix power button wakeup from suspend-to-idle on Surface Pro3) and add a kernel command line switch to tell it to ignore the system sleep blacklist in the ACPI core (Rafael Wysocki). - Fix a race condition related to cpufreq governor module removal and clean up the governor management code in the cpufreq core (Rafael Wysocki). - Drop the unused generic code related to the handling of the static power energy usage model in the CPU cooling thermal driver along with the corresponding documentation (Viresh Kumar). - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng). - Add a new operating point to the imx6ul and imx6q cpufreq drivers and switch the latter to using clk_bulk_get() (Anson Huang, Dong Aisheng). - Add support for multiple regulators to the TI cpufreq driver along with a new DT binding related to that and clean up that driver somewhat (Dave Gerlach). - Fix a powernv cpufreq driver regression leading to incorrect CPU frequency reporting, fix that driver to deal with non-continguous P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat). - Add support for frequency scaling on Armada 37xx SoCs through the generic DT cpufreq driver (Gregory CLEMENT). - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT). - Fix a transition delay setting regression in the longhaul cpufreq driver (Viresh Kumar). - Add Skylake X (server) support to the intel_pstate cpufreq driver and clean up that driver somewhat (Srinivas Pandruvada). - Clean up the cpufreq statistics collection code (Viresh Kumar). - Drop cluster terminology and dependency on physical_package_id from the PSCI driver and drop dependency on arm_big_little from the SCPI cpufreq driver (Sudeep Holla). - Add support for system-wide suspend and resume to the RAPL power capping driver and drop a redundant semicolon from it (Zhen Han, Luis de Bethencourt). - Make SPI domain validation (in the SCSI SPI transport driver) and system-wide suspend mutually exclusive as they rely on the same underlying mechanism and cannot be carried out at the same time (Bart Van Assche). - Fix the computation of the amount of memory to preallocate in the hibernation core and clean up one function in there (Rainer Fiebig, Kyungsik Lee). - Prepare the Operating Performance Points (OPP) framework for being used with power domains and clean up one function in it (Viresh Kumar, Wei Yongjun). - Clean up the generic sysfs interface for device PM (Andy Shevchenko). - Fix several minor issues in power management frameworks and clean them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven, Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker, Sergey Senozhatsky, gaurav jindal). - Make it easier to disable PM via Kconfig (Mark Brown). - Clean up the cpupower and intel_pstate_tracer utilities (Doug Smythies, Laura Abbott)" * tag 'pm-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (89 commits) PCI / PM: Remove spurious semicolon cpufreq: scpi: remove arm_big_little dependency drivers: psci: remove cluster terminology and dependency on physical_package_id powercap: intel_rapl: Fix trailing semicolon dmaengine: rcar-dmac: Make DMAC reinit during system resume explicit PM / runtime: Allow no callbacks in pm_runtime_force_suspend|resume() PM / hibernate: Drop unused parameter of enough_swap PM / runtime: Check ignore_children in pm_runtime_need_not_resume() PM / runtime: Rework pm_runtime_force_suspend/resume() PM / genpd: Stop/start devices without pm_runtime_force_suspend/resume() cpufreq: powernv: Dont assume distinct pstate values for nominal and pmin cpufreq: intel_pstate: Add Skylake servers support cpufreq: intel_pstate: Replace bxt_funcs with core_funcs platform/x86: surfacepro3: Support for wakeup from suspend-to-idle ACPI / PM: Use Low Power S0 Idle on more systems PM / wakeup: Print warn if device gets enabled as wakeup source during sleep PM / domains: Don't skip driver's ->suspend|resume_noirq() callbacks PM / core: Propagate wakeup_path status flag in __device_suspend_late() PM / core: Re-structure code for clearing the direct_complete flag powercap: add suspend and resume mechanism for SOC power limit ...

Pull init_task initializer cleanups from David Howells: "It doesn't seem useful to have the init_task in a header file rather than in a normal source file. We could consolidate init_task handling instead and expand out various macros. Here's a series of patches that consolidate init_task handling: (1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and openrisc. (2) Alter the INIT_TASK_DATA linker script macro to set init_thread_union and init_stack rather than defining these in C. Insert init_task and init_thread_into into the init_stack area in the linker script as appropriate to the configuration, with different section markers so that they end up correctly ordered. We can then get merge ia64's init_task.c into the main one. We then have a bunch of single-use INIT_*() macros that seem only to be macros because they used to be used per-arch. We can then expand these in place of the user and get rid of a few lines and a lot of backslashes. (3) Expand INIT_TASK() in place. (4) Expand in place various small INIT_*() macros that are defined conditionally. Expand them and surround them by #if[n]def/#endif in the .c file as it takes fewer lines. (5) Expand INIT_SIGNALS() and INIT_SIGHAND() in place. (6) Expand INIT_STRUCT_PID in place. These macros can then be discarded" * tag 'init_task-20180117' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: Expand INIT_STRUCT_PID and remove Expand the INIT_SIGNALS and INIT_SIGHAND macros and remove Expand various INIT_* macros and remove Expand INIT_TASK() in init/init_task.c and remove Construct init thread stack in the linker script rather than by union openrisc: Make THREAD_SIZE available to vmlinux.lds hexagon: Make THREAD_SIZE available to vmlinux.lds cris: Make THREAD_SIZE available to vmlinux.lds

Pull x86 fixes from Thomas Gleixner: "A set of small fixes for 4.15: - Fix vmapped stack synchronization on systems with 4-level paging and a large amount of memory caused by a missing 5-level folding which made the pgd synchronization logic to fail and causing double faults. - Add a missing sanity check in the vmalloc_fault() logic on 5-level paging systems. - Bring back protection against accessing a freed initrd in the microcode loader which was lost by a wrong merge conflict resolution. - Extend the Broadwell micro code loading sanity check. - Add a missing ENDPROC annotation in ftrace assembly code which makes ORC unhappy. - Prevent loading the AMD power module on !AMD platforms. The load itself is uncritical, but an unload attempt results in a kernel crash. - Update Peter Anvins role in the MAINTAINERS file" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/ftrace: Add one more ENDPROC annotation x86: Mark hpa as a "Designated Reviewer" for the time being x86/mm/64: Tighten up vmalloc_fault() sanity checks on 5-level kernels x86/mm/64: Fix vmapped stack syncing on very-large-memory 4-level systems x86/microcode: Fix again accessing initrd after having been freed x86/microcode/intel: Extend BDW late-loading further with LLC size check perf/x86/amd/power: Do not load AMD power module on !AMD platforms

Calling fan related SMM functions implemented by Dell BIOS firmware on Dell Vostro 3360 freeze kernel for about 500ms. Unfortunately, it is unlikely for Dell to fix this since the machine is pretty old, so this commit just disables fan support to make the system usable again. Via "force" module param fan support can be enabled.

The hrtimer interrupt code contains a hang detection and mitigation mechanism, which prevents that a long delayed hrtimer interrupt causes a continous retriggering of interrupts which prevent the system from making progress. If a hang is detected then the timer hardware is programmed with a certain delay into the future and a flag is set in the hrtimer cpu base which prevents newly enqueued timers from reprogramming the timer hardware prior to the chosen delay. The subsequent hrtimer interrupt after the delay clears the flag and resumes normal operation. If such a hang happens in the last hrtimer interrupt before a CPU is unplugged then the hang_detected flag is set and stays that way when the CPU is plugged in again. At that point the timer hardware is not armed and it cannot be armed because the hang_detected flag is still active, so nothing clears that flag. As a consequence the CPU does not receive hrtimer interrupts and no timers expire on that CPU which results in RCU stalls and other malfunctions. Clear the flag along with some other less critical members of the hrtimer cpu base to ensure starting from a clean state when a CPU is plugged in. Thanks to Paul, Sebastian and Anna-Maria for their help to get down to the root cause of that hard to reproduce heisenbug. Once understood it's trivial and certainly justifies a brown paperbag.

Due to some unfortunate events, I have not been directly involved in the x86 kernel patch flow for a while now. I have also not been able to ramp back up by now like I had hoped to, and after reviewing what I will need to work on both internally at Intel and elsewhere in the near term, it is clear that I am not going to be able to ramp back up until late 2018 at the very earliest. It is not acceptable to not recognize that this load is currently taken by Ingo and Thomas without my direct participation, so I mark myself as R: (designated reviewer) rather than M: (maintainer) until further notice. This is in fact recognizing the de facto situation for the past few years. I have obviously no intention of going away, and I will do everything within my power to improve Linux on x86 and x86 for Linux. This, however, puts credit where it is due and reflects a change of focus. This patch also removes stale entries for portions of the x86 architecture which have not been maintained separately from arch/x86 for a long time. If there is a reason to re-introduce them then that can happen later. Signed-off-by: H.

Merge tag 'riscv-for-linus-4.15-maintainers' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V update from Palmer Dabbelt: "RISC-V: We have a new mailing list and git repo! Sorry to send something essentially as late as possible (Friday after an rc9), but we managed to get a mailing list for the RISC-V Linux port. We've been using patches@groups.riscv.org for a while, but that list has some problems (it's Google Groups and it's shared over all RISC-V software projects). The new infaread.org list is much better. We just got it on Wednesday but I used it a bit on Thursday to shake out all the configuration problems and it appears to be in working order. When I updated the mailing list I noticed that the MAINTAINERS file was pointing to our github repo, but now that we have a kernel.org repo I'd like to point to that instead so I changed that as well. We'll be centralizing all RISC-V Linux related development here as that seems to be the saner way to go about it. I can understand if it's too late to get this into 4.15, but given that it's not a code change I was hoping it'd still be OK. It would be nice to have the new mailing list and git repo in the release tarballs so when people start to find bugs they'll get to the right place" * tag 'riscv-for-linus-4.15-maintainers' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux: Update the RISC-V MAINTAINERS file

Pull networking fixes from David Miller: 1) The per-network-namespace loopback device, and thus its namespace, can have its teardown deferred for a long time if a kernel created TCP socket closes and the namespace is exiting meanwhile. The kernel keeps trying to finish the close sequence until it times out (which takes quite some time). Fix this by forcing the socket closed in this situation, from Dan Streetman. 2) Fix regression where we're trying to invoke the update_pmtu method on route types (in this case metadata tunnel routes) that don't implement the dst_ops method. Fix from Nicolas Dichtel. 3) Fix long standing memory corruption issues in r8169 driver by performing the chip statistics DMA programming more correctly. From Francois Romieu. 4) Handle local broadcast sends over VRF routes properly, from David Ahern. 5) Don't refire the DCCP CCID2 timer endlessly, otherwise the socket can never be released. From Alexey Kodanev. 6) Set poll flags properly in VSOCK protocol layer, from Stefan Hajnoczi. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: VSOCK: set POLLOUT | POLLWRNORM for TCP_CLOSING dccp: don't restart ccid2_hc_tx_rto_expire() if sk in closed state net: vrf: Add support for sends to local broadcast address r8169: fix memory corruption on retrieval of hardware statistics. net: don't call update_pmtu unconditionally net: tcp: close sock if net namespace is exiting
