Pull device mapper updates from Mike Snitzer: - Update bio-based DM core to always call blk_queue_split() and update DM targets to properly advertise discard limits that blk_queue_split() looks at when dtermining to split discard. Whereby allowing DM core's own 'split_discard_bios' to be removed. - Improve DM cache target to provide support for discard passdown to the origin device. - Introduce support to directly boot to a DM mapped device from init by using dm-mod.create= module param. This eliminates the need for an elaborate initramfs that is otherwise needed to create DM devices. This feature's implementation has been worked on for quite some time (got up to v12) and is of particular interest to Android and other more embedded platforms (e.g. ARM). - Rate limit errors from the DM integrity target that were identified as the cause for recent NMI hangs due to console limitations. - Add sanity checks for user input to thin-pool and external snapshot creation. - Remove some unused leftover kmem caches from when old .request_fn request-based support was removed. - Various small cleanups and fixes to targets (e.g. typos, needless unlikely() annotations, use struct_size(), remove needless .direct_access method from dm-snapshot) * tag 'for-5.1/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm integrity: limit the rate of error messages dm snapshot: don't define direct_access if we don't support it dm cache: add support for discard passdown to the origin device dm writecache: fix typo in name for writeback_wq dm: add support to directly boot to a mapped device dm thin: add sanity checks to thin-pool and external snapshot creation dm block manager: remove redundant unlikely annotation dm verity fec: remove redundant unlikely annotation dm integrity: remove redundant unlikely annotation dm: always call blk_queue_split() in dm_process_bio() dm: fix to_sector() for 32bit dm switch: use struct_size() in kzalloc() dm: remove unused _rq_tio_cache and _rq_cache dm: eliminate 'split_discard_bios' flag from DM target interface dm: update dm_process_bio() to split bio if in ->make_request_fn()

Pull io_uring IO interface from Jens Axboe: "Second attempt at adding the io_uring interface. Since the first one, we've added basic unit testing of the three system calls, that resides in liburing like the other unit tests that we have so far. It'll take a while to get full coverage of it, but we're working towards it. I've also added two basic test programs to tools/io_uring. One uses the raw interface and has support for all the various features that io_uring supports outside of standard IO, like fixed files, fixed IO buffers, and polled IO. The other uses the liburing API, and is a simplified version of cp(1). This adds support for a new IO interface, io_uring. io_uring allows an application to communicate with the kernel through two rings, the submission queue (SQ) and completion queue (CQ) ring. This allows for very efficient handling of IOs, see the v5 posting for some basic numbers: https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/ Outside of just efficiency, the interface is also flexible and extendable, and allows for future use cases like the upcoming NVMe key-value store API, networked IO, and so on. It also supports async buffered IO, something that we've always failed to support in the kernel. Outside of basic IO features, it supports async polled IO as well. This particular feature has already been tested at Facebook months ago for flash storage boxes, with 25-33% improvements. It makes polled IO actually useful for real world use cases, where even basic flash sees a nice win in terms of efficiency, latency, and performance. These boxes were IOPS bound before, now they are not. This series adds three new system calls. One for setting up an io_uring instance (io_uring_setup(2)), one for submitting/completing IO (io_uring_enter(2)), and one for aux functions like registrating file sets, buffers, etc (io_uring_register(2)). Through the help of Arnd, I've coordinated the syscall numbers so merge on that front should be painless. Jon did a writeup of the interface a while back, which (except for minor details that have been tweaked) is still accurate. Find that here: https://lwn.net/Articles/776703/ Huge thanks to Al Viro for helping getting the reference cycle code correct, and to Jann Horn for his extensive reviews focused on both security and bugs in general. There's a userspace library that provides basic functionality for applications that don't need or want to care about how to fiddle with the rings directly. It has helpers to allow applications to easily set up an io_uring instance, and submit/complete IO through it without knowing about the intricacies of the rings. It also includes man pages (thanks to Jeff Moyer), and will continue to grow support helper functions and features as time progresses. Find it here: git://git.kernel.dk/liburing Fio has full support for the raw interface, both in the form of an IO engine (io_uring), but also with a small test application (t/io_uring) that can exercise and benchmark the interface" * tag 'io_uring-2019-03-06' of git://git.kernel.dk/linux-block: io_uring: add a few test tools io_uring: allow workqueue item to handle multiple buffered requests io_uring: add support for IORING_OP_POLL io_uring: add io_kiocb ref count io_uring: add submission polling io_uring: add file set registration net: split out functions related to registering inflight socket files io_uring: add support for pre-mapped user IO buffers block: implement bio helper to add iter bvec pages to bio io_uring: batch io_kiocb allocation io_uring: use fget/fput_many() for file references fs: add fget_many() and fput_many() io_uring: support for IO polling io_uring: add fsync support Add io_uring IO interface

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.1 cycle: Core changes: - The big change this time around is the irqchip handling in the qualcomm pin controllers, closely coupled with the gpiochip. This rework, in a classic fall-between-the-chairs fashion has been sidestepped for too long. The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms have been rewritten to use hierarchical irqchip. This creates the base from which I intend to gradually pull support for hierarchical irqchips into the gpiolib irqchip helpers to cut down on duplicate code. We have too many hacks in the kernel because people have been working around the missing hierarchical irqchip for years, and once it was there, noone understood it for a while. We are now slowly adapting to using it. This is why this pull requests include changes to MFD, SPMI, IRQchip core and some ARM Device Trees pertaining to the Qualcomm chip family. Since Qualcomm have so many chips and such large deployments it is paramount that this platform gets this right, and now it (hopefully) does. - Core support for pull-up and pull-down configuration, also from the device tree. When a simple GPIO chip supports an "off or on" pull-up or pull-down resistor, we provide a way to set this up using machine descriptors or device tree. If more elaborate control of pull up/down (such as resistance shunt setting) is required, drivers should be phased over to use pin control. We do not yet provide a userspace ABI for this pull up-down setting but I suspect the makers are going to ask for it soon enough. PCA953x is the first user of this new API. - The GPIO mockup driver has been revamped after some discussion improving the IRQ simulator in the process. The idea is to make it possible to use the mockup for both testing and virtual prototyping, e.g. when you do not yet have a GPIO expander to play with but really want to get something to develop code around before hardware is available. It's neat. The blackbox testing usecase is currently making its way into kernelci. - ACPI GPIO core preserves non direction flags when updating flags. - A new device core helper for devm_platform_ioremap_resource() is funneled through the GPIO tree with Greg's ACK. New drivers: - TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O) - Gateworks PLD GPIO driver (vaccumed up from OpenWrt) - AMD G-Series PCH (Platform Controller Hub) GPIO driver. - Fintek F81804 & F81966 subvariants. - PCA953x now supports NXP PCAL6416. Driver improvements: - IRQ support on the Nintendo Wii (Hollywood) GPIO. - get_direction() support for the MVEBU driver. - Set the right output level on SAMA5D2. - Drop the unused irq trigger setting on the Spreadtrum driver. - Wakeup support for PCA953x. - A slew of cleanups in the various Intel drivers" * tag 'gpio-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (110 commits) gpio: gpio-omap: fix level interrupt idling gpio: amd-fch: Set proper output level for direction_output x86: apuv2: remove unused variable gpio: pca953x: Use PCA_LATCH_INT platform/x86: fix PCENGINES_APU2 Kconfig warning gpio: pca953x: Fix dereference of irq data in shutdown gpio: amd-fch: Fix type error found by sparse gpio: amd-fch: Drop const from resource gpio: mxc: add check to return defer probe if clock tree NOT ready gpio: ftgpio: Register per-instance irqchip gpio: ixp4xx: Add DT bindings x86: pcengines apuv2 gpio/leds/keys platform driver gpio: AMD G-Series PCH gpio driver drivers: depend on HAS_IOMEM for devm_platform_ioremap_resource() gpio: tqmx86: Set proper output level for direction_output gpio: sprd: Change to use SoC compatible string gpio: sprd: Use SoC compatible string instead of wildcard string gpio: of: Handle both enable-gpio{,s} gpio: of: Restrict enable-gpio quirk to regulator-gpio gpio: davinci: use devm_platform_ioremap_resource() ...

2019-03-08gfs2: Fix missed wakeups in find_insert_glockAndreas Gruenbacher1-1/+1
Mark Syms has reported seeing tasks that are stuck waiting in find_insert_glock. It turns out that struct lm_lockname contains four padding bytes on 64-bit architectures that function glock_waitqueue doesn't skip when hashing the glock name. As a result, we can end up waking up the wrong waitqueue, and the waiting tasks may be stuck forever. Fix that by using ht_parms.key_len instead of sizeof(struct lm_lockname) for the key length.

2019-03-08gpio: gpio-omap: fix level interrupt idlingRussell King1-6/+8
Tony notes that the GPIO module does not idle when level interrupts are in use, as the wakeup appears to get stuck. After extensive investigation, it appears that the wakeup will only be cleared if the interrupt status register is cleared while the interrupt is enabled. However, we are currently clearing it with the interrupt disabled for level-based interrupts. It is acknowledged that this observed behaviour conflicts with a statement in the TRM: CAUTION After servicing the interrupt, the status bit in the interrupt status register (GPIOi.GPIO_IRQSTATUS_0 or GPIOi.GPIO_IRQSTATUS_1) must be reset and the interrupt line released (by setting the corresponding bit of the interrupt status register to 1) before enabling an interrupt for the GPIO channel in the interrupt-enable register (GPIOi.GPIO_IRQSTATUS_SET_0 or GPIOi.GPIO_IRQSTATUS_SET_1) to prevent the occurrence of unexpected interrupts when enabling an interrupt for the GPIO channel. However, this does not appear to be a practical problem. Further, as reported by Grygorii Strashko <grygorii.strashko@ti.com>, the TI Android kernel tree has an earlier similar patch as "GPIO: OMAP: Fix the sequence to clear the IRQ status" saying: if the status is cleared after disabling the IRQ then sWAKEUP will not be cleared and gates the module transition When we unmask the level interrupt after the interrupt has been handled, enable the interrupt and only then clear the interrupt. If the interrupt is still pending, the hardware will re-assert the interrupt status. Should the caution note in the TRM prove to be a problem, we could use a clear-enable-clear sequence instead.

Since commit ad67b74d2469 ("printk: hash addresses printed with %p"), the virtual memory layout printed during boot up contains "ptrval" instead of actual addresses. Instead of changing the printing to "%px", and leaking virtual memory layout information again, just remove the printing completely, cfr. e.g. commits 071929dbdd86 ("arm64: Stop printing the virtual memory layout") and 31833332f798 ("m68k/mm: Stop printing the virtual memory layout"). All interesting information (actual section sizes) is already printed by mem_init_print_info() just above anyway.

2019-03-07mm: create the new vm_fault_t typeSouptick Joarder3-48/+73
Page fault handlers are supposed to return VM_FAULT codes, but some drivers/file systems mistakenly return error numbers. Now that all drivers/file systems have been converted to use the vm_fault_t return type, change the type definition to no longer be compatible with 'int'. By making it an unsigned int, the function prototype becomes incompatible with a function which returns int. Sparse will detect any attempts to return a value which is not a VM_FAULT code. VM_FAULT_SET_HINDEX and VM_FAULT_GET_HINDEX values are changed to avoid conflict with other VM_FAULT codes.
