2020-12-22kasan: inline kasan_reset_tag for tag-based modesAndrey Konovalov1-1/+4
Using kasan_reset_tag() currently results in a function call. As it's called quite often from the allocator code, this leads to a noticeable slowdown. Move it to include/linux/kasan.h and turn it into a static inline function. Also remove the now unneeded reset_tag() internal KASAN macro and use kasan_reset_tag() instead.

2020-12-22kasan, arm64: unpoison stack only with CONFIG_KASAN_STACKAndrey Konovalov1-4/+6
There's a config option CONFIG_KASAN_STACK that has to be enabled for KASAN to use stack instrumentation and perform validity checks for stack variables. There's no need to unpoison stack when CONFIG_KASAN_STACK is not enabled. Only call kasan_unpoison_task_stack[_below]() when CONFIG_KASAN_STACK is enabled. Note, that CONFIG_KASAN_STACK is an option that is currently always defined when CONFIG_KASAN is enabled, and therefore has to be tested with #if instead of #ifdef.

2020-12-22drm/dp_helper: Add support for link failure detectionSwati Sharma1-0/+17
There are specific DPCDs defined for detecting link failures between the PCON and HDMI sink and check the link status. In case of link failure, PCON will communicate the same using an IRQ_HPD to source. HDMI sink would have indicated the same to PCON using SCDC interrupt mechanism. While source can always read final HDMI sink's status using I2C over AUX, it is easier and faster to read the PCONs already read HDMI sink status registers. This patch adds the DPCDs required for link failure detection and provide a helper function for printing error count/lane which might help in debugging the link failure issues. v2: Addressed comments from Uma Shankar: -rephrased the commit message, as per the code. -fixed styling issues -added documentation for the helper function.

2020-12-21Merge tag 'clk-for-linus' of ↵Linus Torvalds14-14/+472
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The core framework got some nice improvements this time around. We gained the ability to get struct clk pointers from a struct clk_hw so that clk providers can consume the clks they provide, if they need to do something like that. This has been a long missing part of the clk provider API that will help us move away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are added for the clk_set_rate() "range" functions, similar to the tracepoints we already have for clk_set_rate() and we added a column to debugfs to help developers understand the hardware enable state of clks in case firmware or bootloader state is different than what is expected. Overall the core changes are mostly improving the clk driver writing experience. At the driver level, we have the usual collection of driver updates and new drivers for new SoCs. This time around the Qualcomm folks introduced a good handful of clk drivers for various parts of three or four SoCs. The SiFive folks added a new clk driver for their FU740 SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that for various new features. One last thing to note in the driver area is that the i.MX driver has gained a new binding to support SCU clks after being on the list for many months. It uses a two cell binding which is sort of rare in clk DT bindings. Beyond that we have the usual set of driver fixes and tweaks that come from more testing and finding out that some configuration was wrong or that a driver could support being built as a module. Summary: Core: - Add some trace points for clk_set_rate() "range" functions - Add hardware enable information to clk_summary debugfs - Replace clk-provider.h with of_clk.h when possible - Add devm variant of clk_notifier_register() - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw New Drivers: - Bindings for Canaan K210 SoC clks - Support for SiFive FU740 PRCI - Camera clks on Qualcomm SC7180 SoCs - GCC and RPMh clks on Qualcomm SDX55 SoCs - RPMh clks on Qualcomm SM8350 SoCs - LPASS clks on Qualcomm SM8250 SoCs Updates: - DVFS support for AT91 clk driver - Update git repo branch for Renesas clock drivers - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E - Stop using __raw_*() I/O accessors in Renesas clk drivers - One more conversion of DT bindings to json-schema - Make i.MX clk-gate2 driver more flexible - New two cell binding for i.MX SCU clks - Drop of_match_ptr() in i.MX8 clk drivers - Add arch dependencies for Rockchip clk drivers - Fix i2s on Rockchip rk3066 - Add MIPI DSI clks on Amlogic axg and g12 SoCs - Support modular builds of Amlogic clk drivers - Fix an Amlogic Video PLL clock dependency - Samsung Kconfig dependencies updates for better compile test coverage - Refactoring of the Samsung PLL clocks driver - Small Tegra driver cleanups - Minor fixes to Ingenic and VC5 clk drivers - Cleanup patches to remove unused variables and plug memory leaks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) dt-binding: clock: Document canaan,k210-clk bindings dt-bindings: Add Canaan vendor prefix clk: vc5: Use "idt,voltage-microvolt" instead of "idt,voltage-microvolts" clk: ingenic: Fix divider calculation with div tables clk: sunxi-ng: Make sure divider tables have sentinel clk: s2mps11: Fix a resource leak in error handling paths in the probe function clk: mvebu: a3700: fix the XTAL MODE pin to MPP1_9 clk: si5351: Wait for bit clear after PLL reset clk: at91: sam9x60: remove atmel,osc-bypass support clk: at91: sama7g5: register cpu clock clk: at91: clk-master: re-factor master clock clk: at91: sama7g5: do not allow cpu pll to go higher than 1GHz clk: at91: sama7g5: decrease lower limit for MCK0 rate clk: at91: sama7g5: remove mck0 from parent list of other clocks clk: at91: clk-sam9x60-pll: allow runtime changes for pll clk: at91: sama7g5: add 5th divisor for mck0 layout and characteristics clk: at91: clk-master: add 5th divisor for mck master clk: at91: sama7g5: allow SYS and CPU PLLs to be exported and referenced in DT dt-bindings: clock: at91: add sama7g5 pll defines clk: at91: sama7g5: fix compilation error ...

Register CPU clock as being the master clock prescaler. This would be used by DVFS. The block schema of SAMA7G5's PMC contains also a divider between master clock prescaler and CPU (PMC_CPU_RATIO.RATIO) but the frequencies supported by SAMA7G5 could be directly received from CPUPLL + master clock prescaler and the extra divider would do no work in case it would be enabled.

We can finally get rid of the old cruft. - Some refactoring and clean up of the core code. - Support edge event timestamps to be stamped using REALTIME (wall clock) timestamps. We have found solid use cases for this, so we support it. New drivers: - MStar MSC313 GPIO driver. - HiSilicon GPIO driver. Driver improvements: - The PCA953x driver now also supports the NXP PCAL9554B/C chips. - The mockup driver can now be probed from the device tree which is pretty useful for virtual prototyping of devices. - The Rcar driver now supports .get_multiple() - The MXC driver dropped some legacy and became a pure device tree client. - The Exar driver was moved over to the IDA interface for enumerating, and also switched over to using regmap for register access" * tag 'gpio-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (87 commits) MAINTAINERS: Remove reference to non-existing file gpio: hisi: Do not require ACPI for COMPILE_TEST MAINTAINERS: Add maintainer for HiSilicon GPIO driver gpio: gpio-hisi: Add HiSilicon GPIO support gpio: cs5535: Simplify the return expression of cs5535_gpio_probe() gpiolib: irq hooks: fix recursion in gpiochip_irq_unmask dt-bindings: mt7621-gpio: convert bindings to YAML format gpiolib: cdev: Flag invalid GPIOs as used gpio: put virtual gpio device into their own submenu drivers: gpio: amd8111: use SPDX-License-Identifier drivers: gpio: amd8111: prefer dev_err()/dev_info() over raw printk drivers: gpio: bt8xx: prefer dev_err()/dev_warn() over of raw printk gpio: Add TODO item for debugfs interface gpio: just plain warning when nonexisting gpio requested tools: gpio: add option to report wall-clock time to gpio-event-mon tools: gpio: add support for reporting realtime event clock to lsgpio gpiolib: cdev: allow edge event timestamps to be configured as REALTIME gpio: msc313: MStar MSC313 GPIO driver dt-bindings: gpio: Binding for MStar MSC313 GPIO controller dt-bindings: gpio: Add a binding header for the MSC313 GPIO driver ...

Pull cifs updates from Steve French: "The largest part are for support of the newer mount API which has been needed for cifs/smb3 mounts for a long time due to the new API's better handling of remount, and better error reporting. There are three additional small cleanup patches for this being tested, that are not included yet. This series also includes addition of support for the SMB3 witness protocol which can provide important notifications from the server to client on server address or export or network changes. This can be useful for example in order to be notified before the failure - when a server's IP address changes (in the future it will allow us to support server notifications of when a share is moved).

2020-12-17drm/i915/gt: Track the overall awake/busy timeChris Wilson1-0/+1
Since we wake the GT up before executing a request, and go to sleep as soon as it is retired, the GT wake time not only represents how long the device is powered up, but also provides a summary, albeit an overestimate, of the device runtime (i.e. the rc0 time to compare against rc6 time). v2: s/busy/awake/ v3: software-gt-awake-time and I915_PMU_SOFTWARE_GT_AWAKE_TIME Signed-off-by: Chris Wilson <[email protected]> Reviewed-by: Tvrtko Ursulin <[email protected]> Cc: Matthew Brost <[email protected]> Reported-by: kernel test robot <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "The major update to this release is that there's a new arch config option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it. All the ftrace callbacks now take a struct ftrace_regs instead of a struct pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will have enough information to read the arguments of the function being traced, as well as access to the stack pointer. This way, if a user (like live kernel patching) only cares about the arguments, then it can avoid using the heavier weight "regs" callback, that puts in enough information in the struct ftrace_regs to simulate a breakpoint exception (needed for kprobes). A new config option that audits the timestamps of the ftrace ring buffer at most every event recorded. Ftrace recursion protection has been cleaned up to move the protection to the callback itself (this saves on an extra function call for those callbacks). Perf now handles its own RCU protection and does not depend on ftrace to do it for it (saving on that extra function call). New debug option to add "recursed_functions" file to tracefs that lists all the places that triggered the recursion protection of the function tracer. This will show where things need to be fixed as recursion slows down the function tracer. The eval enum mapping updates done at boot up are now offloaded to a work queue, as it caused a noticeable pause on slow embedded boards.

git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux Pull modules updates from Jessica Yu: "Summary of modules changes for the 5.11 merge window: - Fix a race condition between systemd/udev and the module loader. The module loader was sending a uevent before the module was fully initialized (i.e., before its init function has been called). This means udev can start processing the module uevent before the module has finished initializing, and some udev rules expect that the module has initialized already upon receiving the uevent. This resulted in some systemd mount units failing if udev processes the event faster than the module can finish init. This is fixed by delaying the uevent until after the module has called its init routine. - Make the linker array sections for kernel params and module version attributes more robust by switching to use the alignment of the type in question. Namely, linker section arrays will be constructed using the alignment required by the struct (using __alignof__()) as opposed to a specific value such as sizeof(void *) or sizeof(long). This is less likely to cause breakages should the size of the type ever change (Johan Hovold) - Fix module state inconsistency by setting it back to GOING when a module fails to load and is on its way out (Miroslav Benes) - Some comment and code cleanups (Sergey Shtylyov)" * tag 'modules-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux: module: delay kobject uevent until after module init call module: drop semicolon from version macro init: use type alignment for kernel parameters params: clean up module-param macros params: use type alignment for kernel parameters params: drop redundant "unused" attributes module: simplify version-attribute handling module: drop version-attribute alignment module: fix comment style module: add more 'kernel-doc' comments module: fix up 'kernel-doc' comments module: only handle errors with the *switch* statement in module_sig_check() module: avoid *goto*s in module_sig_check() module: merge repetitive strings in module_sig_check() module: set MODULE_STATE_GOING state when a module fails to load
