And this adds the saturating size helpers and does a treewide replacement for the struct_size() usage. Additionally this adds the overflow testing modules to make sure everything works. I'm still working on the treewide replacements for allocators with "simple" multiplied arguments: *alloc(a * b, ...) -> *alloc_array(a, b, ...) and *zalloc(a * b, ...) -> *calloc(a, b, ...) as well as the more complex cases, but that's separable from this portion of the series. I expect to have the rest sent before -rc1 closes; there are a lot of messy cases to clean up. Summary: - Introduce arithmetic overflow test helper functions (Rasmus) - Use overflow helpers in 2-factor allocators (Kees, Rasmus) - Introduce overflow test module (Rasmus, Kees) - Introduce saturating size helper functions (Matthew, Kees) - Treewide use of struct_size() for allocators (Kees)" * tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: treewide: Use struct_size() for devm_kmalloc() and friends treewide: Use struct_size() for vmalloc()-family treewide: Use struct_size() for kmalloc()-family device: Use overflow helpers for devm_kmalloc() mm: Use overflow helpers in kvmalloc() mm: Use overflow helpers in kmalloc_array*() test_overflow: Add memory allocation overflow tests overflow.h: Add allocation size calculation helpers test_overflow: Report test failures test_overflow: macrofy some more, do more tests for free lib: add runtime test of check_*_overflow functions compiler.h: enable builtin overflow checkers and add fallback code

* | pinctrl: sunrisepoint: Align GPIO number space with WindowsMika Westerberg2018-05-021-3/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that the Windows GPIO driver for Sunrisepoint PCH-H uses similar bank structure than it does for Cannon Lake with the exception that here the bank size is always 24 pins. Starting from pad group E the BIOS/Windows GPIO numbering does not match the hardware anymore but instead there are gaps to make each pad group ("bank") consume exactly 24 pins. Because of this Linux does not use correct pins for GpioIo/GpioIo resources exposed by the BIOS. This patch aligns the GPIO number space with BIOS/Windows to make sure the same numbering scheme is used in Linux as well following what we did already for Intel Cannon Lake.

* | pinctrl: cherryview: Associate IRQ descriptors to irqdomainMika Westerberg2018-05-021-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we dropped the custom Linux GPIO translation it resulted that the IRQ numbers changed slightly as well. Normally this would be fine because everyone is expected to use controller relative GPIO numbers and ACPI GpioIo/GpioInt resources. However, there is a certain set of Intel_Strago based Chromebooks where i8042 keyboard controller IRQ number is hardcoded be 182 (this is corrected with newer coreboot but the older ones still have the hardcoded Linux IRQ number). Because of this hardcoded IRQ number keyboard on those systems accidentally broke again. Fix this by iteratively associating IRQ descriptors to the chip irqdomain so that there are no gaps on those systems. Other systems are not affected.

| * pinctrl: qcom: Don't allow protected pins to be requestedStephen Boyd2018-03-271-3/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some qcom platforms make some GPIOs or pins unavailable for use by non-secure operating systems, and thus reading or writing the registers for those pins will cause access control issues and reset the device. With a DT/ACPI property to describe the set of pins that are available for use, parse the available pins and set the irq valid bits for gpiolib to know what to consider 'valid'. This should avoid any issues with gpiolib. Furthermore, implement the pinmux_ops::request function so that pinmux can also make sure to not use pins that are unavailable.

This commit introduces support for the main pin controller on H6. The pin bank A and B are not wired out and hidden from the SoC's documents, however it's shown that the "ATE" (an AC200 chip co-packaged with the H6 die) is connected to the main SoC die via these pin banks. The information about these banks is just copied from the BSP pinctrl driver, but re-formatted to fit the mainline pinctrl driver format. The GPIO functions are dropped, as they're impossible to use -- except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In certain cases interrupt enablement will be delayed relative to when the InterruptEnable bits are written. One example of this is when a GPIO's "debounce" logice is first enabled. After enabling debounce, there is a 900 us "warm up" period during which InterruptEnable[0] (bit 11) will read as 0 despite being written 1. During this time InterruptSts will not be updated, nor will interrupts be delivered, even if the GPIO's interrupt configuration has been written to the register. To work around this delay, poll the InterruptEnable bits after setting them to ensure interrupts have truly been enabled in hardware before returning from the irq_enable handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The U8540 was an evolved version of the U8500, but it was never mass produced or put into products, only reference designs exist. The upstream support was never completed and it is unlikely that this will happen so drop the support for now to simplify maintenance of the U8500.

Add the missing pin to restore consistency. Note that technically TX_ER is an optional signal in the MII bus, and thus could have its own group, but this is currently not supported by any R-Car Gen2 pin controller driver.

On R8A77965 the INTC-EX hardware handles pins IRQ0 -> IRQ5 and this patch adds support for them to the PFC driver as "intc_ex_irqN".
