2017-06-29ftrace: Fix regression with module command in stack_trace_filterSteven Rostedt (VMware)
When doing the following command: # echo ":mod:kvm_intel" > /sys/kernel/tracing/stack_trace_filter it triggered a crash. This happened with the clean up of probes. It required all callers to the regex function (doing ftrace filtering) to have ops->private be a pointer to a trace_array. But for the stack tracer, that is not the case. Allow for the ops->private to be NULL, and change the function command callbacks to handle the trace_array pointer being NULL as well.

2017-06-29gpio: acpi: Skip _AEI entries without a handler rather then aborting the scanHans de Goede
acpi_walk_resources will stop as soon as the callback passed in returns an error status. On a x86 tablet I have the first GpioInt in the _AEI resource list has no handler defined in the DSDT, causing acpi_walk_resources to abort scanning the rest of the resource list, which does define valid ACPI GPIO events. This commit changes the return for not finding a handler from AE_BAD_PARAMETER to AE_OK so that the rest of the resource list will get scanned normally in case of missing event handlers.

2017-06-29Add USB quirk for HVR-950q to avoid intermittent device resetsDevin Heitmueller
The USB core and sysfs will attempt to enumerate certain parameters which are unsupported by the au0828 - causing inconsistent behavior and sometimes causing the chip to reset. Avoid making these calls. This problem manifested as intermittent cases where the au8522 would be reset on analog video startup, in particular when starting up ALSA audio streaming in parallel - the sysfs entries created by snd-usb-audio on streaming startup would result in unsupported control messages being sent during tuning which would put the chip into an unknown state.

2017-06-29EDAC, i5000, i5400: Fix definition of NRECMEMB registerJérémy Lefaure
In the i5000 and i5400 drivers, the NRECMEMB register is defined as a 16-bit value, which results in wrong shifts in the code, as reported by sparse. In the datasheets ([1], section 3.9.22.20 and [2], section 3.9.22.21), this register is a 32-bit register. A u32 value for the register fixes the wrong shifts warnings and matches the datasheet. Also fix the mask to access to the CAS bits [27:16] in the i5000 driver.

2017-06-29PM / Domains: Handle safely genpd_syscore_switch() call on non-genpd deviceKrzysztof Kozlowski
genpd_syscore_switch() had two problems: 1. It silently assumed that device, it is being called for, belongs to generic power domain and used container_of() on its power domain pointer. Such assumption might not be true always. 2. It iterated over list of generic power domains without holding gpd_list_lock mutex thus list could have been modified at the same time. Usage of genpd_lookup_dev() solves both problems as it is safe a call for non-generic power domains and uses mutex when iterating.

2017-06-29timers: Make the cpu base lock rawSebastian Andrzej Siewior
The timers cpu base lock could not be converted to a raw spinlock becaue the lock held time was non-deterministic due to cascading and long lasting timer wheel traversals. The rework of the timer wheel to the new non-cascading model removed also the wheel traversals and the lock held times are deterministic now. This allows to make the lock raw and thereby unbreaks NOHz* on preempt-RT.

The patch fixes the issue. HTX has been run with +60 hours without failure." Since __blkdev_direct_IO_simple() allocates the bio on the stack, it doesn't go through the regular bio free. This means that any ancillary data allocated with the bio through the stack is not freed. Hence, we can leak the integrity data associated with the bio, if the device is using DIF/DIX. Fix this by providing a bio_uninit() and export it, so that we can use it to free this data. Note that this is a minimal fix for this issue. Any current user of bio's that are allocated outside of bio_alloc_bioset() suffers from this issue, most notably some drivers. We will fix those in a more comprehensive patch for 4.13. This also means that the commit marked as being fixed by this isn't the real culprit, it's just the most obvious one out there.

2017-06-28regulator: core: Fix voltage change propagations to supply regulatorsTirupathi Reddy
Some regulators support get_voltage() and some support get_voltage_sel() operations but currently we only propagate changes if the regulator has a get_voltage() operation. Also do this if we've got get_voltage_sel() [Rewite commit message for clarity -- broonie] Signed-off-by: Tirupathi Reddy <tirupath@codeaurora.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-06-28spi: stm32: enhance DMA error managementAmelie Delaunay
This patch reworks DMA error management. In case the DMA callback is called while EOT (End Of Transfer) flag is not set, that means that DMA encountered an error. This error will result in an auto-suspend of SPI flow, which could also result in an overrun. So, in DMA mode, SUSP and OVR flags are a condition to stop the current transfer. Moreover, stm32_spi_can_dma doesn't care about the state of dma channels. During driver probe, master->can_dma is initialised if dma channel request is successful. That's why we must use master->can_dma to know if dma use is possible (dma channel are successfully requested and the transfer size is greater than fifo size).
