2019-05-09nfp: bpf: fix static check error through tightening shift amount adjustmentJiong Wang1-1/+12
NFP shift instruction has something special. If shift direction is left then shift amount of 1 to 31 is specified as 32 minus the amount to shift. But no need to do this for indirect shift which has shift amount be 0. Even after we do this subtraction, shift amount 0 will be turned into 32 which will eventually be encoded the same as 0 because only low 5 bits are encoded, but shift amount be 32 will fail the FIELD_PREP check done later on shift mask (0x1f), due to 32 is out of mask range. Such error has been observed when compiling nfp/bpf/jit.c using gcc 8.3 + O3. This issue has started when indirect shift support added after which the incoming shift amount to __emit_shf could be 0, therefore it is at that time shift amount adjustment inside __emit_shf should have been tightened.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk framework updates from Stephen Boyd: "We have a couple new features and changes in the core clk framework this time around because we've finally gotten around to fixing some long standing issues. There's still work to do though, so this pull request is largely laying down the foundation for all the driver changes to come in the next merge window. The first problem we're alleviating is how parents of clks are specified. With the new method, we should see lots of drivers migrate away from the current design of string comparisons on the entire clk tree to a more direct method where they can use clk_hw pointers or more localized names specified in DT or via clkdev. This should reduce our reliance on string comparisons for all the topology description logic that we've been using for years and hopefully speed some things up while avoiding problems we have with generating clk names. Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't really helping anyone and we introduced big-endian versions of the basic clk types so that we can get rid of clk_{readl,writel}(). Both of these are things that driver developers have tried to use over the years that I typically bat away during code reviews because they're not useful. It's great to see these two things go away so maintainers can save time not worrying about these things. On the driver side we got the usual collection of new SoC support and non-critical fixes and updates to existing code. The big topics that stand out are the new driver support for Mediatek MT8183 and MT8516 SoCs, Amlogic Meson8b and G12a SoCs, and the SiFive FU540 SoC. The other patches in the driver pile are mostly fixes for things that are being used for the first time or additions for clks that couldn't be tested before because there wasn't a consumer driver that exercised them. Details are below and also in the sub-maintainer tags. Core: - Remove clk_readl() and introduce BE versions of basic clk types - Rewrite how clk parents can be specified to allow DT/clkdev lookups - Removal of the CLK_IS_BASIC clk flag - Framework documentation updates and fixes New Drivers: - Support for STM32F769 - AT91 sam9x60 PMC support - SiFive FU540 PRCI and PLL support - Qualcomm QCS404 CDSP clk support - Qualcomm QCS404 Turing clk support - Mediatek MT8183 clock support - Mediatek MT8516 clock support - Milbeaut M10V clk controller support - Support for Cirrus Logic Lochnagar clks Updates: - Rework AT91 sckc DT bindings - Fix slow RC oscillator issue on sama5d3 - Mark UFS clk as critical on Hi-Silicon hi3660 SoCs - Various static analysis fixes/finds and const markings - Video Engine (ECLK) support on Aspeed SoCs - Xilinx ZynqMP Versal platform support - Convert Xilinx ZynqMP driver to be struct oriented - Fixes for Rockchip rk3328 and rk3288 SoCs - Sub-type for Rockchip SoCs where mux and divider aren't a single register - Remove SNVS clock from i.MX7UPL clock driver and bindings - Improve i.MX5 clock driver for i.MX50 support - Addition of ADC clock definition for Exynos 5410 SoC (Odroid XU) - Export a new clock for the MBUS controller on the A13 - Allwinner H6 fixes to support a finer clocking of the video and VPU engines - Add g12a support in the Amlogic axg audio clock controller - Add missing PCI USB clock on Rensas RZ/N1 - Add Z2 (Cortex-A53) clocks on Rensas R-Car E3 and RZ/G2E - A new helper DIV64_U64_ROUND_CLOSEST() in <linux/math64.h> - VPU and Video Decoder clocks on Amlogic Meson8b - Finally remove the wrong ABP Meson8b clock id - Add Video Decoder, PCIe PLL, and CPU Clocks on Amlogic G12A - Re-expose SAR_ADC_SEL and CTS_OSCIN on Amlogic G12A AO clock controller - Un-expose some Amlogic AXG-Audio input clocks IDs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (172 commits) clk: Cache core in clk_fetch_parent_index() without names clk: imx: correct pfdv2 gate_bit/vld_bit operations clk: sifive: add a driver for the SiFive FU540 PRCI IP block clk: analogbits: add Wide-Range PLL library clk: imx: clk-pllv3: mark expected switch fall-throughs clk: imx8mq: Add dsi_ipg_div clk: imx: pllv4: add fractional-N pll support clk: sunxi-ng: Use the correct style for SPDX License Identifier clk: sprd: Use the correct style for SPDX License Identifier clk: renesas: Use the correct style for SPDX License Identifier clk: qcom: Use the correct style for SPDX License Identifier clk: davinci: Use the correct style for SPDX License Identifier clk: actions: Use the correct style for SPDX License Identifier clk: imx: keep uart clock on during system boot clk: imx: correct i.MX7D AV PLL num/denom offset dt-bindings: clk: add documentation for the SiFive PRCI driver clk: stm32mp1: Add ddrperfm clock clk: Remove CLK_IS_BASIC clk flag clock: milbeaut: Add Milbeaut M10V clock controller dt-bindings: clock: milbeaut: add Milbeaut clock description ...

2019-05-09PCI: pciehp: Replace pciehp_debug module param with dyndbgFrederick Lawler2-13/+6
Previously pciehp debug messages were enabled by the pciehp_debug module parameter, e.g., by booting with this kernel command line option: pciehp.pciehp_debug=1 Convert this mechanism to use the generic dynamic debug (dyndbg) feature. After this commit, pciehp debug messages are enabled by building the kernel with CONFIG_DYNAMIC_DEBUG=y and booting with this command line option: dyndbg="file pciehp* +p" The dyndbg facility is much more flexible: messages can be enabled at boot- or run-time based on the file name, function name, line number, message test, etc. See Documentation/admin-guide/dynamic-debug-howto.rst for more details.

2019-05-09tuntap: synchronize through tfiles array instead of tun->numqueuesJason Wang1-1/+6
When a queue(tfile) is detached through __tun_detach(), we move the last enabled tfile to the position where detached one sit but don't NULL out last position. We expect to synchronize the datapath through tun->numqueues. Unfortunately, this won't work since we're lacking sufficient mechanism to order or synchronize the access to tun->numqueues. To fix this, NULL out the last position during detaching and check RCU protected tfile against NULL instead of checking tun->numqueues in datapath.

2019-05-09pwm: meson: Add clock source configuration for Meson G12ANeil Armstrong1-0/+30
For the PWM controller in the Meson G12A SoC, the EE domain and AO domain have different clock sources. This patch tries to describe them in the DT compatible data. The two AO PWM controller has different clock source, but the first AO controller (A & B) can reuse the AXG parents name.

2019-05-09pwm: samsung: Don't uses devm_*() functions in ->request()Uwe Kleine-König1-2/+2
A call to ->request() is always paired by a call to ->free() before a given device is disposed. So the simplification that usually is possible when using devm_*() functions cannot be used here. So use plain kzalloc() and kfree() for improved runtime behaviour and reduced memory footprint.

2019-05-09pwm: meson: Use the spin-lock only to protect register modificationsMartin Blumenstingl1-8/+17
Holding the spin-lock for all of the code in meson_pwm_apply() can result in a "BUG: scheduling while atomic". This can happen because clk_get_rate() (which is called from meson_pwm_calc()) may sleep. Only hold the spin-lock when modifying registers to solve this. The reason why we need a spin-lock in the driver is because the REG_MISC_AB register is shared between the two channels provided by one PWM controller. The only functions where REG_MISC_AB is modified are meson_pwm_enable() and meson_pwm_disable() so the register reads/writes in there need to be protected by the spin-lock. The original code also used the spin-lock to protect the values in struct meson_pwm_channel. This could be necessary if two consumers can use the same PWM channel. However, PWM core doesn't allow this so we don't need to protect the values in struct meson_pwm_channel with a lock.
