2019-07-04PM / QOS: Pass request type to dev_pm_qos_{add|remove}_notifier()Viresh Kumar
In order to use the same set of routines to register notifiers for different request types, update the existing dev_pm_qos_{add|remove}_notifier() routines with an additional parameter: request-type. For now, it only supports resume-latency request type but will be extended to frequency limit (min/max) constraints later on.

2019-07-04iommu/arm-smmu-v3: Invalidate ATC when detaching a deviceJean-Philippe Brucker
We make the invalid assumption in arm_smmu_detach_dev() that the ATC is clear after calling pci_disable_ats(). For one thing, only enabling the PCIe ATS capability constitutes an implicit invalidation event, so the comment was wrong. More importantly, the ATS capability isn't necessarily disabled by pci_disable_ats() in a PF, if the associated VFs have ATS enabled. Explicitly invalidate all ATC entries in arm_smmu_detach_dev(). The endpoint cannot form new ATC entries because STE.EATS is clear.

2019-07-04gpio: stp-xway: improve module clock error handlingMartin Blumenstingl
Three module clock error handling improvements: - use devm_clk_get() so the clock instance can be freed if devm_gpiochip_add_data() fails later on - switch to clk_prepare_enable() so the driver is ready whenever the lantiq target switches to the common clock framework - disable the clock again (using clk_disable_unprepare()) if devm_gpiochip_add_data() All of these are virtually no-ops with the current lantiq target. However, these will be relevant if we switch to the common clock framework.

2019-07-03net/mlx5: Refactor mlx5_esw_query_functions for modularityParav Pandit
Functions change event output data size changes when functions other than VFs will be enabled in HCA CAP. With current API, multiple callers needs to align, calculate accurate size of the output data depending on number on non VF functions enabled in the device. Instead of duplicating such math at multiple places, refactor mlx5_esw_query_functions() to return raw output allocated by itself. Caller must free the allocated memory using kvfree() as described in the function comment section. This hides calcuation within mlx5_esw_query_functions() and provides simpler API.

2019-07-03drm/amdkfd: Print a warning when the runlist becomes oversubscribedFelix Kuehling
Oversubscription of queues or processes results in poor performance mostly because HWS blinbly schedules busy and idle queues, resulting in poor occupancy if many queues are idle. Let users know with a warning message when transitioning from a non-oversubscribed to an oversubscribed runlist.

2019-07-03driver: core: Allow subsystems to continue deferring probeThierry Reding
Some subsystems, such as pinctrl, allow continuing to defer probe indefinitely. This is useful for devices that depend on resources provided by devices that are only probed after the init stage. One example of this can be seen on Tegra, where the DPAUX hardware contains pinmuxing controls for pins that it shares with an I2C controller. The I2C controller is typically used for communication with a monitor over HDMI (DDC). However, other instances of the I2C controller are used to access system critical components, such as a PMIC. The I2C controller driver will therefore usually be a builtin driver, whereas the DPAUX driver is part of the display driver that is loaded from a module to avoid bloating the kernel image with all of the DRM/KMS subsystem. In this particular case the pins used by this I2C/DDC controller become accessible very late in the boot process. However, since the controller is only used in conjunction with display, that's not an issue. Unfortunately the driver core currently outputs a warning message when a device fails to get the pinctrl before the end of the init stage. That can be confusing for the user because it may sound like an unwanted error occurred, whereas it's really an expected and harmless situation. In order to eliminate this warning, this patch allows callers of the driver_deferred_probe_check_state() helper to specify that they want to continue deferring probe, regardless of whether we're past the init stage or not. All of the callers of that function are updated for the new signature, but only the pinctrl subsystem passes a true value in the new persist parameter if appropriate.

2019-07-03drivers: base: cacheinfo: Ensure cpu hotplug work is done before Intel RDTJames Morse
The cacheinfo structures are alloced/freed by cpu online/offline callbacks. Originally these were only used by sysfs to expose the cache topology to user space. Without any in-kernel dependencies CPUHP_AP_ONLINE_DYN was an appropriate choice. resctrl has started using these structures to identify CPUs that share a cache. It updates its 'domain' structures from cpu online/offline callbacks. These depend on the cacheinfo structures (resctrl_online_cpu()->domain_add_cpu()->get_cache_id()-> get_cpu_cacheinfo()). These also run as CPUHP_AP_ONLINE_DYN. Now that there is an in-kernel dependency, move the cacheinfo work earlier so we know its done before resctrl's CPUHP_AP_ONLINE_DYN work runs.
