2017-10-20x86/kasan: Use the same shadow offset for 4- and 5-level pagingAndrey Ryabinin1-1/+1
We are going to support boot-time switching between 4- and 5-level paging. For KASAN it means we cannot have different KASAN_SHADOW_OFFSET for different paging modes: the constant is passed to gcc to generate code and cannot be changed at runtime. This patch changes KASAN code to use 0xdffffc0000000000 as shadow offset for both 4- and 5-level paging. For 5-level paging it means that shadow memory region is not aligned to PGD boundary anymore and we have to handle unaligned parts of the region properly. In addition, we have to exclude paravirt code from KASAN instrumentation as we now use set_pgd() before KASAN is fully ready.

David Howells says: ==================== rxrpc: Add bits for kernel services Here are some patches that add a few things for kernel services to use: (1) Allow service upgrade to be requested and allow the resultant actual service ID to be obtained. (2) Allow the RTT time of a call to be obtained. (3) Allow a kernel service to find out if a call is still alive on a server between transmitting a request and getting the reply. (4) Allow data transmission to ignore signals if transmission progress is being made in reasonable time. This is also usable by userspace by passing MSG_WAITALL to sendmsg()[*].

2017-10-20dt-bindings: net: sh_eth: add R-Car Gen[12] fallback compatibility stringsSimon Horman1-2/+12
Add fallback compatibility strings for R-Car Gen 1 and 2. In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme is being adopted for drivers for Renesas SoCs. Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The approach that has been consistently taken for other IP blocks is to name common code, compatibility strings and so on after R-Car Gen2.

2017-10-20powerpc/tm: Add commandline option to disable hardware transactional memoryCyril Bur1-0/+4
Currently the kernel relies on firmware to inform it whether or not the CPU supports HTM and as long as the kernel was built with CONFIG_PPC_TRANSACTIONAL_MEM=y then it will allow userspace to make use of the facility. There may be situations where it would be advantageous for the kernel to not allow userspace to use HTM, currently the only way to achieve this is to recompile the kernel with CONFIG_PPC_TRANSACTIONAL_MEM=n. This patch adds a simple commandline option so that HTM can be disabled at boot time.

Pull "more soc changes for omaps for v4.15 merge window" from Tony Lindgren: Drop omap legacy platform data for IRQ, DMA and IO resources. With the dts files fixed up to contain the necessary data for basic resources, we can drop the related platform data. Note that this branch depends on the "omap-for-v4.15/fixes-dt-signed" branch and the patches with dependencies are based on a merge with that branch. These patches first ensure things keep working for the legacy "ti,hwmods" property when we start making it optional, then adds a minimal TI sysc interconnect target device driver to handle the new generic "ti,sysc" compatible property. And then we can finally drop the legacy platform data for IRQ, DMA and IO resources as seen in the diffstats. * tag 'omap-for-v4.15/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (25 commits) bus: ti-sysc: Fix unbalanced pm_runtime_enable by adding remove bus: ti-sysc: mark PM functions as __maybe_unused ARM: OMAP2+: omap_device: fix error return code in omap_device_copy_resources() ARM: OMAP2+: Drop legacy struct omap_hwmod_addr_space ARM: OMAP2+: Drop omap_hwmod_dma_info ARM: OMAP2+: Drop omap_hwmod_irq_info ARM: OMAP4: Remove legacy IRQ for PRM ARM: OMAP3: Remove legacy IRQ for PRM bus: ti-sysc: Add minimal TI sysc interconnect target driver ARM: OMAP2+: Populate legacy resources for dma and smartreflex ARM: OMAP2+: Parse module IO range from dts for legacy "ti,hwmods" support ARM: dts: Configure SmartReflex only to idle the interconnect target module ARM: dts: Add nodes for missing omap4 interconnect target modules dt-bindings: bus: Minimal TI sysc interconnect target module binding ARM: dts: Add missing hwmod related properties for dra7 ARM: dts: Add missing hwmod related nodes for am33xx ARM: dts: Add missing dma hwmod property for omap5 ARM: dts: Add missing wdt3 node for omap4 ARM: dts: Add missing hsi node for omap4 ARM: dts: Add missing onewire node for omap4 ...

Pull "non-urgent device tree fixes for omaps for v4.15 merge window" from Tony Lindgren Non-urgent device tree fixes for omaps that can all wait for v4.15 merge window. Turns out that we have many devices working just because we have the legacy platform data still around. This is mostly an issue for omap4, other SoCs just have minimal fixes needed. As many of the missing device tree nodes and properties are for devices that have no drivers in the mainline kernel, such as slimbus, iss, mcasp, aess, fdif and gpu, we might as well start using the new "ti,sysc" interconnect target module binding for them so we can get the devices with no child device drivers idled. This also makes it possible to drop unnecessary platform data in later patches. * tag 'omap-for-v4.15/fixes-dt-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Fix typo for omap4 mcasp rx path ARM: dts: Configure SmartReflex only to idle the interconnect target module ARM: dts: Add nodes for missing omap4 interconnect target modules dt-bindings: bus: Minimal TI sysc interconnect target module binding ARM: dts: Add missing hwmod related properties for dra7 ARM: dts: Add missing hwmod related nodes for am33xx ARM: dts: Add missing dma hwmod property for omap5 ARM: dts: Add missing wdt3 node for omap4 ARM: dts: Add missing hsi node for omap4 ARM: dts: Add missing onewire node for omap4 ARM: dts: Add missing smartreflex node and binding for omap4 ARM: dts: Add missing hwmods property for omap4 dma ARM: dts: Add missing properties for omap4 control modules ARM: dts: Configure pmu without interrupt for omap4430 ARM: dts: Add missing dma hwmods property for omap3

Many serially-attached GPIO and IIO devices are daisy-chainable. Examples for GPIO devices are Maxim MAX3191x and TI SN65HVS88x: https://datasheets.maximintegrated.com/en/ds/MAX31913.pdf http://www.ti.com/lit/ds/symlink/sn65hvs880.pdf Examples for IIO devices are TI DAC128S085 and TI DAC161S055: http://www.ti.com/lit/ds/symlink/dac128s085.pdf http://www.ti.com/lit/ds/symlink/dac161s055.pdf We already have drivers for daisy-chainable devices in the tree but their devicetree bindings are somewhat inconsistent and ill-named: The gpio-74x164.c driver uses "registers-number" to convey the number of devices in the daisy-chain. (Sans vendor prefix, multiple vendors sell compatible versions of this chip.) The gpio-pisosr.c driver takes a different approach and calculates the number of devices in the daisy-chain by dividing the common "ngpios" property (Documentation/devicetree/bindings/gpio/gpio.txt) by 8 (which assumes that each chip has 8 inputs). Let's standardize on a common "#daisy-chained-devices" property. That name was chosen because it's the term most frequently used in datasheets. (A less frequently used synonym is "cascaded devices".)

2017-10-19gpio: Introduce ->get_multiple callbackLukas Wunner1-11/+30
SPI-attached GPIO controllers typically read out all inputs in one go. If callers desire the values of multipe inputs, ideally a single readout should take place to return the desired values. However the current driver API only offers a ->get callback but no ->get_multiple (unlike ->set_multiple, which is present). Thus, to read multiple inputs, a full readout needs to be performed for every single value (barring driver-internal caching), which is inefficient. In fact, the lack of a ->get_multiple callback has been bemoaned repeatedly by the gpio subsystem maintainer: http://www.spinics.net/lists/linux-gpio/msg10571.html http://www.spinics.net/lists/devicetree/msg121734.html Introduce the missing callback. Add corresponding consumer functions such as gpiod_get_array_value(). Amend linehandle_ioctl() to take advantage of the newly added infrastructure. Update the documentation.

2017-10-19documentation: kernel-api: add more info on bitmap functionsRandy Dunlap1-0/+12
There are some good comments about bitmap operations in lib/bitmap.c and include/linux/bitmap.h, so format them for document generation and pull them into core-api/kernel-api.rst. I converted the "tables" of functions from using tabs to using spaces so that they are more readable in the source file and in the generated output.

2017-10-19irqchip/gic-v3-its: Workaround HiSilicon Hip07 redistributor addressingMarc Zyngier1-0/+1
The ITSes on the Hip07 (as present in the Huawei D05) are broken when it comes to addressing the redistributors, and need to be explicitely told to address the VLPI page instead of the redistributor base address. So let's add yet another quirk, fixing up the target address in the command stream. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2017-10-19irqchip/gic-v3: Add workaround for Synquacer pre-ITSArd Biesheuvel1-0/+4
The Socionext Synquacer SoC's implementation of GICv3 has a so-called 'pre-ITS', which maps 32-bit writes targeted at a separate window of size '4 << device_id_bits' onto writes to GITS_TRANSLATER with device ID taken from bits [device_id_bits + 1:2] of the window offset. Writes that target GITS_TRANSLATER directly are reported as originating from device ID #0. So add a workaround for this. Given that this breaks isolation, clear the IRQ_DOMAIN_FLAG_MSI_REMAP flag as well.

2017-10-19livepatch: add (un)patch callbacksJoe Lawrence1-0/+605
Provide livepatch modules a klp_object (un)patching notification mechanism. Pre and post-(un)patch callbacks allow livepatch modules to setup or synchronize changes that would be difficult to support in only patched-or-unpatched code contexts. Callbacks can be registered for target module or vmlinux klp_objects, but each implementation is klp_object specific. - Pre-(un)patch callbacks run before any (un)patching transition starts. - Post-(un)patch callbacks run once an object has been (un)patched and the klp_patch fully transitioned to its target state. Example use cases include modification of global data and registration of newly available services/handlers. See Documentation/livepatch/callbacks.txt for details and samples/livepatch/ for examples.

This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME] (R8A7743/5) usbhs is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,rcar-gen2-usbhs". Adding the SoC-specific compatible values here has two purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values.
