Ido Schimmel says: ==================== mlxsw: Various static checkers fixes Jakub told me he gets some warnings with W=1, so I decided to check with sparse, smatch and coccinelle as well. This patch set fixes all the issues found. None are actual bugs / regressions and therefore not targeted at net. Patches #1-#2 add missing kernel-doc comments. Patch #3 removes dead code. Patch #4 reworks the ACL code to avoid defining a static variable in a header file. Patch #5 removes unnecessary conversion to bool that coccinelle warns about. Patch #6 avoids false-positive uninitialized symbol errors emitted by smatch. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2020-03-27gpiolib: Introduce gpiod_set_config()Geert Uytterhoeven
The GPIO Aggregator will need a method to forward a .set_config() call to its parent gpiochip. This requires obtaining the gpio_chip and offset for a given gpio_desc. While gpiod_to_chip() is public, gpio_chip_hwgpio() is not, so there is currently no method to obtain the needed GPIO offset parameter. Hence introduce a public gpiod_set_config() helper, which invokes the .set_config() callback through a gpio_desc pointer, like is done for most other gpio_chip callbacks. Rewrite the existing gpiod_set_debounce() helper as a wrapper around gpiod_set_config(), to avoid duplication.

This causes most of the changed lines of the DT updates this time. - More Allwinner updates fixing the identification of the security system on sun8i/A33, a recent regression of the A83t ethernet, and a few board specific issues on the TBS-A711 macine. - Several bug fixes for OMAP dts files, most notably fixing the timings for the NAND flash on the Nokia N900 that regressed a while ago after the move to configuring them from DT. Some other OMAPs now set the correct dma limits on the L3 bus, and a regression fix addresses lost Ethernet on dm814x - One incorrect setting in the newly added Raspberry Pi Zero W that may cause issues with the SD card controller. - A missing property on the bcm2835 firmware node caused incorrect DMA settings. - An old bug on the oxnas platform causing spurious interrupts is finally addressed. - A regression on the Exynos Midas board broke the OLED panel power supply. - The i.MX6 phycore SoM specified the wrong voltage for the SoC, this is now set to the values from the datasheet. - Some 64-bit machines use a deprecated string to identify the PSCI firmware. There are also several small code fixes addressing mostly serious issues: - Fix the sunxi rsb bus access to no longer return incorrect data when mixing 8 and 16 bit I/O. - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing quirk in the ti-sysc driver - Fix a NULL pointer access from a race in the fsl dpio driver - Fix a v5.5 regression in the exynos-chipid driver that caused an invalid error code probing the device on non-exynos platforms - Fix an out-of-bounds access in the AMD TEE driver" * tag 'arm-soc-fixes-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (24 commits) soc: samsung: chipid: Fix return value on non-Exynos platforms arm64: dts: Fix leftover entry-methods for PSCI ARM: dts: exynos: Fix regulator node aliasing on Midas-based boards ARM: dts: oxnas: Fix clear-mask property ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations ARM: dts: omap5: Add bus_dma_limit for L3 bus ARM: dts: omap4-droid4: Fix lost touchscreen interrupts ARM: dts: dra7: Add bus_dma_limit for L3 bus ARM: bcm2835-rpi-zero-w: Add missing pinctrl name ARM: dts: sun8i: a33: add the new SS compatible dt-bindings: crypto: add new compatible for A33 SS ARM: dts: sun8i: r40: Move SPI device nodes based on address order ARM: dts: sun8i: r40: Fix register base address for SPI2 and SPI3 ARM: dts: sun8i: r40: Move AHCI device node based on address order ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage soc: fsl: dpio: register dpio irq handlers after dpio create tee: amdtee: out of bounds read in find_session() ARM: dts: N900: fix onenand timings bus: ti-sysc: Fix quirk flags for lcdc on am335x ARM: dts: Fix dm814x Ethernet by changing to use rgmii-id mode ...

2020-03-27ftrace: Make function trace pid filtering a bit more exactSteven Rostedt (VMware)
The set_ftrace_pid file is used to filter function tracing to only trace tasks that are listed in that file. Instead of testing the pids listed in that file (it's a bitmask) at each function trace event, the logic is done via a sched_switch hook. A flag is set when the next task to run is in the list of pids in the set_ftrace_pid file. But the sched_switch hook is not at the exact location of when the task switches, and the flag gets set before the task to be traced actually runs. This leaves a residue of traced functions that do not belong to the pid that should be filtered on. By changing the logic slightly, where instead of having a boolean flag to test, record the pid that should be traced, with special values for not to trace and always trace. Then at each function call, a check will be made to see if the function should be ignored, or if the current pid matches the function that should be traced, and only trace if it matches (or if it has the special value to always trace).
