Pull stream_open() updates from Kirill Smelkov: "This time on stream_open front it is only two small changes: - the first one converts stream_open.cocci to treat all functions that start with wait_.* as blocking. Previously it was only wait_event_.* functions that were considered as blocking, but this was falsely reporting several deadlock cases as only warning. This was picked by linux-kbuild and entered mainline as commit 0c4ab18f ("coccinelle: api/stream_open: treat all wait_.*() calls as blocking"), and already merged earlier. - the second one teaches stream_open.cocci to consider files as being stream-like even if they use noop_llseek.

Pull x86 platform driver updates from Andy Shevchenko: "Gathered a bunch of x86 platform driver changes. It's rather big, since includes two big refactors and completely new driver: - ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. - Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. - From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. - Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. - The OLPC XO-1.75 platform is now supported. - CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. - Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal.

This patch continues 10dce8af (fs: stream_open - opener for stream-like files so that read and write can run simultaneously without deadlock) and c5bf68fe (*: convert stream-like files from nonseekable_open -> stream_open) and teaches steam_open.cocci to consider files as being stream-like not only if they have .llseek=no_llseek, but also if they have .llseek=noop_llseek. This is safe to do: the comment about noop_llseek says This is an implementation of ->llseek useable for the rare special case when userspace expects the seek to succeed but the (device) file is actually not able to perform the seek. In this case you use noop_llseek() instead of falling back to the default implementation of ->llseek. and in general noop_llseek was massively added to drivers in 6038f373 (llseek: automatically add .llseek fop) when changing default for NULL .llseek from NOP to no_llseek with the idea to avoid breaking compatibility, if maybe some user-space program was using lseek on a device without caring about the result, but caring if it was an error or not. Amended semantic patch produces two changes when applied tree-wide: drivers/hid/hid-sensor-custom.c:690:8-24: WARNING: hid_sensor_custom_fops: .read() has stream semantic; safe to change nonseekable_open -> stream_open. drivers/input/mousedev.c:564:1-17: ERROR: mousedev_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.3 kernel cycle: Core changes: - Device links can optionally be added between a pin control producer and its consumers. This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...

But I think it does make sense to have certain core ops available directly, especially those that can support a "try this non-blocking" flag/mode. (me) - Handle generic short reads automatically. This can happen fairly easily if parts of the buffered read is cached. Since the application needs to issue another request for the remainder, just do this internally and save kernel/user roundtrip while providing a nicer more robust API. (me) - Support for linked SQEs. This allows SQEs to depend on each other, enabling an application to eg queue a read-from-this-file,write-to-that-file pair.

The stats variable nr_unused_locks is incremented every time a new lock class is register and decremented when the lock is first used in __lock_acquire(). And after all, it is shown and checked in lockdep_stats. However, under configurations that either CONFIG_TRACE_IRQFLAGS or CONFIG_PROVE_LOCKING is not defined: The commit: 09180651 ("locking/lockdep: Consolidate lock usage bit initialization") missed marking the LOCK_USED flag at IRQ usage initialization because as mark_usage() is not called. And the commit: 886532ae ("locking/lockdep: Move mark_lock() inside CONFIG_TRACE_IRQFLAGS && CONFIG_PROVE_LOCKING") further made mark_lock() not defined such that the LOCK_USED cannot be marked at all when the lock is first acquired. As a result, we fix this by not showing and checking the stats under such configurations for lockdep_stats. Reported-by:

If a user first sample a PEBS event on a fixed counter, then sample a non-PEBS event on the same fixed counter on Icelake, it will trigger spurious NMI. For example: perf record -e 'cycles:p' -a perf record -e 'cycles' -a The error message for spurious NMI: [June 21 15:38] Uhhuh. NMI received for unknown reason 30 on CPU 2. [ +0.000000] Do you have a strange power saving mode enabled? [ +0.000000] Dazed and confused, but trying to continue The bug was introduced by the following commit: commit 6f55967a ("perf/x86/intel: Fix race in intel_pmu_disable_event()") The commit moves the intel_pmu_pebs_disable() after intel_pmu_disable_fixed(), which returns immediately. The related bit of PEBS_ENABLE MSR will never be cleared for the fixed counter. Then a non-PEBS event runs on the fixed counter, but the bit on PEBS_ENABLE is still set, which triggers spurious NMIs. Check and disable PEBS for fixed counters after intel_pmu_disable_fixed(). Reported-by:

So far, we tried to disallow grouping exclusive events for the fear of complications they would cause with moving between contexts. Specifically, moving a software group to a hardware context would violate the exclusivity rules if both groups contain matching exclusive events. This attempt was, however, unsuccessful: the check that we have in the perf_event_open() syscall is both wrong (looks at wrong PMU) and insufficient (group leader may still be exclusive), as can be illustrated by running: $ perf record -e '{intel_pt//,cycles}' uname $ perf record -e '{cycles,intel_pt//}' uname ultimately successfully. Furthermore, we are completely free to trigger the exclusivity violation by: perf -e '{cycles,intel_pt//}' -e '{intel_pt//,instructions}' even though the helpful perf record will not allow that, the ABI will. The warning later in the perf_event_open() path will also not trigger, because it's also wrong. Fix all this by validating the original group before moving, getting rid of broken safeguards and placing a useful one to perf_install_in_context(). Signed-off-by:

The following commit: d7cbbe49 ("perf/x86/amd/uncore: Set ThreadMask and SliceMask for L3 Cache perf events") enables L3 PMC events for all threads and slices by writing 1's in 'ChL3PmcCfg' (L3 PMC PERF_CTL) register fields. Those bitfields overlap with high order event select bits in the Data Fabric PMC control register, however. So when a user requests raw Data Fabric events (-e amd_df/event=0xYYY/), the two highest order bits get inadvertently set, changing the counter select to events that don't exist, and for which no counts are read. This patch changes the logic to write the L3 masks only when dealing with L3 PMC counters. AMD Family 16h and below Northbridge (NB) counters were not affected. Signed-off-by:

Which is a 'fun' confluence of fail; copy_process() doing an unconditional free_task() and not respecting refcounts, and perf having creative locking. In particular: 82d94856 ("perf/core: Fix lock inversion between perf,trace,cpuhp") seems to have overlooked this 'fun' parade. Solve it by using the fact that detached events still have a reference count on their (previous) context. With this perf_event_free_task() can detect when events have escaped and wait for their destruction. Debugged-by:

Commit 0e5a610b ("ppp: mppe: switch to RC4 library interface"), which was merged through the crypto tree for v5.3, changed ppp_mppe.c to use the new arc4_crypt() library function rather than access RC4 through the dynamic crypto_skcipher API. Meanwhile commit aad1dcc4 ("ppp: mppe: Add softdep to arc4") was merged through the net tree and added a module soft-dependency on "arc4". The latter commit no longer makes sense because the code now uses the "libarc4" module rather than "arc4", and also due to the direct use of arc4_crypt(), no module soft-dependency is required.
