2016-08-19thermal: cpu_cooling: Fix NULL dereference in cpufreq_state2powerBrendan Jackman
Currently all CPU cooling devices share a `struct thermal_cooling_device_ops` instance. The thermal core uses the presence of functions in this struct to determine if a cooling device has a power model (see cdev_is_power_actor). cpu_cooling.c adds the power model functions to the shared struct when a device is registered with a power model. Therefore, if a CPU cooling device is registered using [of_]cpufreq_power_cooling_register, _all_ devices will be determined to have a power model, including any registered with [of_]cpufreq_cooling_register. This can result in cpufreq_state2power being called on a device where dyn_power_table is NULL. With this commit, instead of having a shared thermal_cooling_device_ops which is mutated, we have two versions: one with the power functions and one without.

2016-08-19gpio: make any OF dependent driver depend on OF_GPIOLinus Walleij
The drivers that depend on OF but not OF_GPIO are wreaking havoc with the autobuilders for archs that have all requirements for OF but not for OF_GPIO, particularly the UM (Usermode) arch does not have iomem (NO_IOMEM) which result in configuring GPIOLIB but without OF_GPIO which is wrong if the driver is using the .of_node of the gpiochip, which only appears with OF_GPIO. After a brief look at the drivers just depending on OF it seems most if not all of them actually require stuff from gpiolib-of so the dependency is wrong in the first place. This simply patches the Kconfig so that all GPIO drivers using OF depend on OF_GPIO rather than just OF.

The disable_bypass cmdline option changes the SMMUv3 driver to put down faulting stream table entries by default, as opposed to bypassing transactions from unconfigured devices. In this mode of operation, it is entirely expected to see aborting entries in the stream table if and when we come to installing a valid translation, so don't trigger a BUG() as a result of misdiagnosing these entries as stream table corruption.

2016-08-19iommu/arm-smmu: Disable stalling faults for all endpointsWill Deacon
Enabling stalling faults can result in hardware deadlock on poorly designed systems, particularly those with a PCI root complex upstream of the SMMU. Although it's not really Linux's job to save hardware integrators from their own misfortune, it *is* our job to stop userspace (e.g. VFIO clients) from hosing the system for everybody else, even if they might already be required to have elevated privileges. Given that the fault handling code currently executes entirely in IRQ context, there is nothing that can sensibly be done to recover from things like page faults anyway, so let's rip this code out for now and avoid the potential for deadlock.

2016-08-19irqchip/gicv3-its: Disable the ITS before initializing itDavid Daney
When starting a kexec/kdump kernel, the GIC ITS will already have been enabled. According to the ARM Generic Interrupt Controller Architecture Specification (GIC architecture Version 3.0 and version 4.0), writing to GITS_BASER<n> or GITS_CBASER is "UNPREDICTABLE" when the ITS is enabled. On Cavium Thunder systems, this prevents the ITS from being initializing in the kexec/kdump kernel, resulting in failure to register/enable interrupts for all devices. The fix is to disable the ITS if it is not already in the disabled state. This allows the ITS to be properly initialized and then re-enabled in the kexec/kdump kernel.

2016-08-19iommu/arm-smmu: Fix CMDQ error handlingWill Deacon
In the unlikely event of a global command queue error, the ARM SMMUv3 driver attempts to convert the problematic command into a CMD_SYNC and resume the command queue. Unfortunately, this code is pretty badly broken: 1. It uses the index into the error string table as the CMDQ index, so we probably read the wrong entry out of the queue 2. The arguments to queue_write are the wrong way round, so we end up writing from the queue onto the stack. These happily cancel out, so the kernel is likely to stay alive, but the command queue will probably fault again when we resume. This patch fixes the error handling code to use the correct queue index and write back the CMD_SYNC to the faulting entry.

2016-08-19iommu/io-pgtable-arm-v7s: Fix attributes when splitting blocksRobin Murphy
Due to the attribute bits being all over the place in the different types of short-descriptor PTEs, when remapping an existing entry, e.g. splitting a section into pages, we take the approach of decomposing the PTE attributes back to the IOMMU API flags to start from scratch. On inspection, though, the existing code seems to have got the read-only bit backwards and ignored the XN bit. How embarrassing... Fortunately the primary user so far, the Mediatek IOMMU, both never splits blocks (because it only serves non-overlapping DMA API calls) and also ignores permissions anyway, but let's put things right before any future users trip up.

BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can be found in two packages (versions): BCM53573 and BCM47189. It shares some code with the Northstar family, but also requires some new quirks. First of all there can be up to 2 Ethernet cores on this SoC. If that is the case, they are connected to two different switch ports allowing some more complex/optimized setups. It seems the second unit doesn't come fully configured and requires some IRQ quirk. Other than that only the first core is connected to the PHY. For the second one we have to register fixed PHY (similarly to the Northstar), otherwise generic PHY driver would get some invalid info.

In the case where a descriptor is chained on a running channel, and as explained in the comment in the code 10 lines above, the success of the chaining is ensured either if : - the DMA is still running - or if the chained transfer is completed Unfortunately the transfer completness test was done on the descriptor to which the transfer was chained, and not the transfer being chained at the end, ie. hot-chained. This corner case is extremely hard to trigger, as usually the DMA chain is still running, and the first case takes care of returning success of the hot-chaining. It was seen by hot-chaining several "small transfers" to a running "big transfer", not in a real-life usecase but by testing the robustness of the driver.
