git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk由 Linus Torvalds 提交于
Pull printk updates from Petr Mladek: - Add Petr Mladek, Sergey Senozhatsky as printk maintainers, and Steven Rostedt as the printk reviewer. This idea came up after the discussion about printk issues at Kernel Summit. It was formulated and discussed at lkml[1]. - Extend a lock-less NMI per-cpu buffers idea to handle recursive printk() calls by Sergey Senozhatsky[2]. It is the first step in sanitizing printk as discussed at Kernel Summit. The change allows to see messages that would normally get ignored or would cause a deadlock. Also it allows to enable lockdep in printk(). This already paid off. The testing in linux-next helped to discover two old problems that were hidden before[3][4]. - Remove unused parameter by Sergey Senozhatsky. Clean up after a past change.

Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for direct mapped LPC on POWER9, giving Linux direct access to devices that may be on there such as a UART. - Memory hotplug support for the Power9 Radix MMU. - Add new AUX vectors describing the processor's cache geometry, to be used by glibc. - The ability for a guest to ask the hypervisor to resize the guest's hash table, and in addition support for doing so automatically when memory is hotplugged into/out-of the guest. This allows the hash table to be sized based on the current memory usage of the guest, rather than the maximum possible memory usage. - Implementation of optprobes (kprobe optimisation) for powerpc. In addition there's the topic branch shared with the KVM tree, which includes support for guests to use the Radix MMU on Power9.

Pull pin control updates from Linus Walleij: "Pin control bulk changes for the v4.11 kernel cycle. Core changes: - Switch the generic pin config argument from 16 to 24 bits, only use 8 bits for the configuration type. We might need to encode more information about a certain setting than we need to encode different generic settings. - Add a cross-talk API to the pin control GPIO back-end, utilizing pinctrl_gpio_set_config() from GPIO drivers that want to set up a certain pin configuration in the back-end. This also includes the .set_config() refactoring of the GPIO chips, so that they pass a generic configuration for things like debouncing and single ended (typically open drain). This change has also been merged in an immutable branch to the GPIO tree. - Take hogs with a delayed work, so that we finalize probing a pin controller before trying to get any hogs. - For pin controllers putting all group and function definitions into the device tree, we now have generic code to deal with this and it is used in two drivers so far. - Simplifications of the pin request conflict check. - Make dt_free_map() optional. Updates to drivers: - pinctrl-single now use the generic helpers to generate dynamic group and function tables from the device tree. - Texas Instruments IOdelay configuration driver add-on to pinctrl-single. - i.MX: use radix trees to store groups and functions, use the new generic group and function helpers to manage them. - Intel: add support for hardware debouncing and 1K pull-down. New subdriver for the Gemini Lake SoC. - Renesas SH-PFC: drive strength and bias support, CAN bus muxing, MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791. - Aspeed: use syscon cross-dependencies to set up related bits in the LPC host controller and display controller. - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs. Add banks Y, Z, AA, AB and AC. - AMD: support additional GPIO. - STM32: set this controller to strict muxing mode. STM32H743 MCU support. - Allwinner sunxi: deep simplifications on how to support subvariants of SoCs without adding to much SoC-specific data for each subvariant, especially for sun5i variants. New driver for V3s SoCs. New driver for the H5 SoC. Support A31/A31s variants with the new variant framework. - Mvebu: simplifications to use a MMIO and regmap abstraction. New subdrivers for the 98DX3236, 98DX5241 SoCs. - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC driver to access regmaps. Add infrastructure for pin-bank retention control. Clean out the pin retention control from arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in the Samsung pin control driver(s). - Meson: add HDMI HPD/DDC pins.

Commit 279967a6 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi") unconditionally switches over handling of all Synaptics touchpads to hid-rmi (to make use of extended features of the HW); in case CONFIG_HID_RMI is disabled though this renders the touchpad unusable, as the HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID) match doesn't exist and generic/multitouch doesn't bind to it either (due to hid group mismatch). Fix this by switching over to hid-rmi only if it has been actually built.

Pull block layer updates from Jens Axboe: - blk-mq scheduling framework from me and Omar, with a port of the deadline scheduler for this framework. A port of BFQ from Paolo is in the works, and should be ready for 4.12. - Various fixups and improvements to the above scheduling framework from Omar, Paolo, Bart, me, others. - Cleanup of the exported sysfs blk-mq data into debugfs, from Omar. This allows us to export more information that helps debug hangs or performance issues, without cluttering or abusing the sysfs API. - Fixes for the sbitmap code, the scalable bitmap code that was migrated from blk-mq, from Omar. - Removal of the BLOCK_PC support in struct request, and refactoring of carrying SCSI payloads in the block layer. This cleans up the code nicely, and enables us to kill the SCSI specific parts of struct request, shrinking it down nicely. From Christoph mainly, with help from Hannes. - Support for ranged discard requests and discard merging, also from Christoph. - Support for OPAL in the block layer, and for NVMe as well. Mainly from Scott Bauer, with fixes/updates from various others folks. - Error code fixup for gdrom from Christophe. - cciss pci irq allocation cleanup from Christoph. - Making the cdrom device operations read only, from Kees Cook. - Fixes for duplicate bdi registrations and bdi/queue life time problems from Jan and Dan. - Set of fixes and updates for lightnvm, from Matias and Javier. - A few fixes for nbd from Josef, using idr to name devices and a workqueue deadlock fix on receive. Also marks Josef as the current maintainer of nbd. - Fix from Josef, overwriting queue settings when the number of hardware queues is updated for a blk-mq device. - NVMe fix from Keith, ensuring that we don't repeatedly mark and IO aborted, if we didn't end up aborting it. - SG gap merging fix from Ming Lei for block. - Loop fix also from Ming, fixing a race and crash between setting loop status and IO. - Two block race fixes from Tahsin, fixing request list iteration and fixing a race between device registration and udev device add notifiations. - Double free fix from cgroup writeback, from Tejun. - Another double free fix in blkcg, from Hou Tao. - Partition overflow fix for EFI from Alden Tondettar. * tag 'for-4.11/linus-merge-signed' of git://git.kernel.dk/linux-block: (156 commits) nvme: Check for Security send/recv support before issuing commands. block/sed-opal: allocate struct opal_dev dynamically block/sed-opal: tone down not supported warnings block: don't defer flushes on blk-mq + scheduling blk-mq-sched: ask scheduler for work, if we failed dispatching leftovers blk-mq: don't special case flush inserts for blk-mq-sched blk-mq-sched: don't add flushes to the head of requeue queue blk-mq: have blk_mq_dispatch_rq_list() return if we queued IO or not block: do not allow updates through sysfs until registration completes lightnvm: set default lun range when no luns are specified lightnvm: fix off-by-one error on target initialization Maintainers: Modify SED list from nvme to block Move stack parameters for sed_ioctl to prevent oversized stack with CONFIG_KASAN uapi: sed-opal fix IOW for activate lsp to use correct struct cdrom: Make device operations read-only elevator: fix loading wrong elevator type for blk-mq devices cciss: switch to pci_irq_alloc_vectors block/loop: fix race between I/O and set_status blk-mq-sched: don't hold queue_lock when calling exit_icq block: set make_request_fn manually in blk_mq_update_nr_hw_queues ...

Commit 004172bd ("sched/core: Remove unnecessary #include headers") removed the inclusion of asm/paravirt.h which is used to get declarations of paravirt_steal_rq_enabled and paravirt_steal_clock. It is implicitly included on x86 but not on arm and arm64 breaking the build if paravirtualization is used. Since things from that header are used directly fix the build by putting the direct inclusion back.

Commit 34b88a68 ("net: Fix use after free in the recvmmsg exit path"), changed the exit path of recvmmsg to always return the datagrams variable and modified the error paths to set the variable to the error code returned by recvmsg if necessary. However in the case sock_error returned an error, the error code was then ignored, and recvmmsg returned 0. Change the error path of recvmmsg to correctly return the error code of sock_error. The bug was triggered by using recvmmsg on a CAN interface which was not up. Linux 4.6 and later return 0 in this case while earlier releases returned -ENETDOWN.
