2020-12-11Revert "scsi: storvsc: Validate length of incoming packet in ↵Andrea Parri (Microsoft)
storvsc_on_channel_callback()" This reverts commit 3b8c72d076c42bf27284cda7b2b2b522810686f8. Dexuan reported a regression where StorVSC fails to probe a device (and where, consequently, the VM may fail to boot). The root-cause analysis led to a long-standing race condition that is exposed by the validation /commit in question. Let's put the new validation aside until a proper solution for that race condition is in place.

2020-12-11driver core: platform: Add devm_platform_get_irqs_affinity()John Garry
Drivers for multi-queue platform devices may also want managed interrupts for handling HW queue completion interrupts, so add support. The function accepts an affinity descriptor pointer, which covers all IRQs expected for the device. The function is devm class as the only current in-tree user will also use devm method for requesting the interrupts; as such, the function is made as devm as it can ensure ordering of freeing the irq and disposing of the mapping.

2020-12-11irqchip/gic-v3-its: Flag device allocation as proxied if behind a PCI bridgeMarc Zyngier

2020-12-11platform-msi: Track shared domain allocationMarc Zyngier
We have two flavours of platform-MSI: - MSIs generated by devices for themselves (the usual case) - MSIs generated on behalf of other devices, as the generating device is some form of bridge (either a wire-to-MSI bridge, or even a non-transparent PCI bridge that repaints the PCI requester ID). In the latter case, the underlying interrupt architecture may need to track this in order to keep the mapping alive even when no MSI are currently being generated. Add a set of flags to the generic msi_alloc_info_t structure, as well as the MSI_ALLOC_FLAGS_PROXY_DEVICE flag that will get advertized by the platform-MSI code when allocating an irqdomain for a device.

2020-12-11irqchip/ti-sci-intr: Fix freeing of irqsLokesh Vutla
ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in data->chip_data and uses it for calling ti_sci irq_free() and then mark the out_irq as available resource. But ti_sci_intr_irq_domain_alloc() is storing p_hwirq(parent's hardware irq) which is translated from out_irq. This is causing resource leakage and eventually out_irq resources might be exhausted. Fix ti_sci_intr_irq_domain_alloc() by storing the out_irq in data->chip_data.

2020-12-11irqchip/gic, gic-v3: Make SGIs use handle_percpu_devid_irq()Valentin Schneider
handle_percpu_devid_fasteoi_ipi() states: * The biggest difference with the IRQ version is that the interrupt is * EOIed early, as the IPI could result in a context switch, and we need to * make sure the IPI can fire again All that can actually happen scheduler-wise within the handling of an IPI is the raising of TIF_NEED_RESCHED (and / or folding thereof into preempt_count); see scheduler_ipi() or sched_ttwu_pending() for instance. Said flag / preempt_count is evaluated some time later before returning to whatever context was interrupted, and this gates a call to preempt_schedule_irq() (arm64_preempt_schedule_irq() in arm64). Per the above, SGI's do not need a different handler than PPI's, so make them use the same (handle_percpu_devid_irq).

2020-12-11thermal/core: Add critical and hot opsDaniel Lezcano
Currently there is no way to the sensors to directly call an ops in interrupt mode without calling thermal_zone_device_update assuming all the trip points are defined. A sensor may want to do something special if a trip point is hot or critical. This patch adds the critical and hot ops to the thermal zone device, so a sensor can directly invoke them or let the thermal framework to call the sensor specific ones.

2020-12-11thermal/core: Emit a warning if the thermal zone is updated without opsDaniel Lezcano
The actual code is silently ignoring a thermal zone update when a driver is requesting it without a get_temp ops set. That looks not correct, as the caller should not have called this function if the thermal zone is unable to read the temperature. That makes the code less robust as the check won't detect the driver is inconsistently using the thermal API and that does not help to improve the framework as these circumvolutions hide the problem at the source. In order to detect the situation when it happens, let's add a warning when the update is requested without the get_temp() ops set. Any warning emitted will have to be fixed at the source of the problem: the caller must not call thermal_zone_device_update if there is not get_temp callback set.

Register devfreq cooling device and attempt to register Energy Model. This will add the devfreq device to the Energy Model framework. It will create a dedicated and unified data structures used i.e. in thermal framework. It uses simplified Energy Model, created based on voltage, frequency and DT 'dynamic-power-coefficient'.

Remove old power model and use new Energy Model to calculate the power budget. It drops static + dynamic power calculations and power table in order to use Energy Model performance domain data. This model should be easy to use and could find more users. It is also less complicated to setup the needed structures.

Devfreq cooling needs to now the correct status of the device in order to operate. Devfreq framework can change the device status in the background. To mitigate issues make a copy of the status structure and use it for internal calculations. In addition this patch adds normalization function, which also makes sure that whatever data comes from the device, the load will be in range from 1 to 1024.

2020-12-11iommu/amd: Add sanity check for interrupt remapping table length macrosSuravee Suthikulpanit
Currently, macros related to the interrupt remapping table length are defined separately. This has resulted in an oversight in which one of the macros were missed when changing the length. To prevent this, redefine the macros to add built-in sanity check. Also, rename macros to use the name of the DTE[IntTabLen] field as specified in the AMD IOMMU specification. There is no functional change.
