2019-11-28i2c: replace i2c_new_probed_device with an ERR_PTR variantWolfram Sang1-6/+19
In the general move to have i2c_new_*_device functions which return ERR_PTR instead of NULL, this patch converts i2c_new_probed_device(). There are only few users, so this patch converts the I2C core and all users in one go. The function gets renamed to i2c_new_scanned_device() so out-of-tree users will get a build failure to understand they need to adapt their error checking code.

2019-11-28Merge branch 'vmwgfx-coherent' of ↵Dave Airlie14-116/+1543
git://people.freedesktop.org/~thomash/linux into drm-next Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver to provide coherent graphics memory, meaning that the GPU sees any content written to the coherent memory on the next GPU operation that touches that memory, and the CPU sees any content written by the GPU to that memory immediately after any fence object trailing the GPU operation is signaled. Paravirtual drivers that otherwise require explicit synchronization needs to do this by hooking up dirty tracking to pagefault handlers and buffer object validation. Provide mm helpers needed for this and that also allow for huge pmd- and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7). The code has been tested and exercised by a tailored version of mesa where we disable all explicit synchronization and assume graphics memory is coherent. The performance loss varies of course; a typical number is around 5%.

2019-11-27net: wireless: intel: iwlwifi: fix GRO_NORMAL packet stallingAlexander Lobakin1-2/+11
Commit 6570bc79c0df ("net: core: use listified Rx for GRO_NORMAL in napi_gro_receive()") has applied batched GRO_NORMAL packets processing to all napi_gro_receive() users, including mac80211-based drivers. However, this change has led to a regression in iwlwifi driver [1][2] as it is required for NAPI users to call napi_complete_done() or napi_complete() and the end of every polling iteration, whilst iwlwifi doesn't use NAPI scheduling at all and just calls napi_gro_flush(). In that particular case, packets which have not been already flushed from napi->rx_list stall in it until at least next Rx cycle. Fix this by adding a manual flushing of the list to iwlwifi driver right before napi_gro_flush() call to mimic napi_complete() logics. I prefer to open-code gro_normal_list() rather than exporting it for 2 reasons: * to prevent from using it and napi_gro_flush() in any new drivers, as it is the *really* bad way to use NAPI that should be avoided; * to keep gro_normal_list() static and don't lose any CC optimizations. I also don't add the "Fixes:" tag as the mentioned commit was only a trigger that only exposed an improper usage of NAPI in this particular driver.

That work has been happening for the past few kernel releases and will continue over time, it's a long-term project/goal The driver core device link support missed 5.4 by just a bit, so it's been sitting and baking for many months now. It's from Saravana Kannan to help resolve the problems that DT-based systems have at boot time with dependancy graphs and kernel modules. Turns out that no one has actually tried to build a generic arm64 kernel with loads of modules and have it "just work" for a variety of platforms (like a distro kernel). The big problem turned out to be a lack of dependency information between different areas of DT entries, and the work here resolves that problem and now allows devices to boot properly, and quicker than a monolith kernel.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for v5.5. It is pretty much business as usual, the most interesting thing I think is the pin controller for a new Intel chip called Lightning Mountain, which is according to news reports some kind of embedded network processor and what is surprising about it is that Intel have decided to use device tree to describe the system rather than ACPI that they have traditionally favored. Core changes: - Avoid taking direct references to device tree-supplied device names: these may changed at runtime under certain circumstances to kstrdup them. GPIO related: - Work is ongoing to move to passing the irqchip along as a templated struct gpio_irq_chip when adding a standard gpiolib-based irqchip to a GPIO controller, a few patches in this cycle switches a few pin control drivers over to using this method. New hardware support: - Intel Lightning Mountain SoC pin controller and GPIO support, a first Intel platform to use device tree rather than ACPI to configure the system. News reports says that this SoC is a network processor. - Qualcomm MSM8976 and MSM8956 - Qualcomm PMIC GPIO now also supports PM6150 and PM6150L - Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950 - Rockchip RK3308 - Renesas R8A77961 - Allwinner Meson-A1 Driver improvements: - get_multiple and set_multiple support for the AT91-PIO4 driver. - Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers in the GPIOlib irqchip" * tag 'pinctrl-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (93 commits) pinctrl: ingenic: Add OTG VBUS pin for the JZ4770 pinctrl: ingenic: Handle PIN_CONFIG_OUTPUT config pinctrl: Fix Kconfig indentation pinctrl: lewisburg: Update pin list according to v1.1v6 MAINTAINERS: Replace my email by one @kernel.org pinctrl: armada-37xx: Fix irq mask access in armada_37xx_irq_set_type() dt-bindings: pinctrl: intel: Add for new SoC pinctrl: Add pinmux & GPIO controller driver for a new SoC pinctrl: rza1: remove unnecessary static inline function pinctrl: meson: add pinctrl driver support for Meson-A1 SoC pinctrl: meson: add a new callback for SoCs fixup pinctrl: nomadik: db8500: Add mc0_a_2 pin group without direction control dt-bindings: pinctrl: Convert generic pin mux and config properties to schema pinctrl: cherryview: Missed type change to unsigned int pinctrl: intel: Missed type change to unsigned int pinctrl: use devm_platform_ioremap_resource() to simplify code pinctrl: just return if no valid maps dt-bindings: pinctrl: qcom-pmic-mpp: Add support for PM/PMI8950 pinctrl: qcom: spmi-mpp: Add PM/PMI8950 compatible strings dt-bindings: pinctrl: qcom-pmic-gpio: Add support for PM/PMI8950 ...

The load-balancing rework is the most intrusive change: it replaces the old heuristics that have become less meaningful after the introduction of the PELT metrics, with a grounds-up load-balancing algorithm. As such it's not really an iterative series, but replaces the old load-balancing logic with the new one. We hope there are no performance regressions left - but statistically it's highly probable that there *is* going to be some workload that is hurting from these chnages.
