2019-01-02xprtrdma: Yet another double DMA-unmapChuck Lever
While chasing yet another set of DMAR fault reports, I noticed that the frwr recycler conflates whether or not an MR has been DMA unmapped with frwr->fr_state. Actually the two have only an indirect relationship. It's in fact impossible to guess reliably whether the MR has been DMA unmapped based on its fr_state field, especially as the surrounding code and its assumptions have changed over time. A better approach is to track the DMA mapping status explicitly so that the recycler is less brittle to unexpected situations, and attempts to DMA-unmap a second time are prevented.

Add a comment to perf_session__register_idle_thread() to bring attention to a pitfall with the idle task thread structure.

2019-01-02perf thread-stack: Fix thread stack processing for the idle taskAdrian Hunter
perf creates a single 'struct thread' to represent the idle task. That is because threads are identified by PID and TID, and the idle task always has PID == TID == 0. However, there are actually separate idle tasks for each CPU. That creates a problem for thread stack processing which assumes that each thread has a single stack, not one stack per CPU. Fix that by passing through the CPU number, and in the case of the idle "thread", pick the thread stack from an array based on the CPU number.

2019-01-02thermal: generic-adc: Fix adc to temp interpolationBjorn Andersson
First correct the edge case to return the last element if we're outside the range, rather than at the last element, so that interpolation is not omitted for points between the two last entries in the table. Then correct the formula to perform linear interpolation based the two points surrounding the read ADC value. The indices for temp are kept as "hi" and "lo" to pair with the adc indices, but there's no requirement that the temperature is provided in descendent order. mult_frac() is used to prevent issues with overflowing the int.

2019-01-02thermal: armada: add overheat interrupt supportMiquel Raynal
The IP can manage to trigger interrupts on overheat situation from all the sensors. However, the interrupt source changes along with the last selected source (ie. the last read sensor), which is an inconsistent behavior. Avoid possible glitches by always selecting back only one channel which will then be referenced as the "overheat_sensor" (arbitrarily: the first in the DT which has a critical trip point filled in). It is possible that the scan of all thermal zone nodes did not bring a critical trip point from which the overheat interrupt could be configured. In this case just complain but do not fail the probe. Also disable sensor switch during overheat situations because changing the channel while the system is too hot could clear the overheat state by changing the source while the temperature is still very high. Even if the overheat state is not declared, overheat interrupt must be cleared by reading the DFX interrupt cause _after_ the temperature has fallen down to the low threshold, otherwise future possible interrupts would not be served. A work polls the corresponding register until the overheat flag gets cleared in this case.

2019-01-01PCI: imx: Enable MSI from downstream componentsRichard Zhu
The MSI Enable bit in the MSI Capability (PCIe r4.0, sec 7.7.1.2) controls whether a Function can request service using MSI. i.MX6 Root Ports implement the MSI Capability and may use MSI to request service for events like PME, hotplug, AER, etc. In addition, on i.MX6, the MSI Enable bit controls delivery of MSI interrupts from components below the Root Port. Prior to f3fdfc4ac3a2 ("PCI: Remove host driver Kconfig selection of CONFIG_PCIEPORTBUS"), enabling CONFIG_PCI_IMX6 automatically also enabled CONFIG_PCIEPORTBUS, and when portdrv claimed the Root Ports, it set the MSI Enable bit so it could use PME, hotplug, AER, etc. As a side effect, that also enabled delivery of MSI interrupts from downstream components. The imx6q-pcie driver itself does not depend on portdrv, so set MSI Enable in imx6q-pcie so MSI from downstream components works even if nobody uses MSI for the Root Port events.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: - Page table code for AMD IOMMU now supports large pages where smaller page-sizes were mapped before. VFIO had to work around that in the past and I included a patch to remove it (acked by Alex Williamson) - Patches to unmodularize a couple of IOMMU drivers that would never work as modules anyway. - Work to unify the the iommu-related pointers in 'struct device' into one pointer. This work is not finished yet, but will probably be in the next cycle. - NUMA aware allocation in iommu-dma code - Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver - Scalable mode support for the Intel VT-d driver - PM runtime improvements for the ARM-SMMU driver - Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom - Various smaller fixes and improvements * tag 'iommu-updates-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (78 commits) iommu: Check for iommu_ops == NULL in iommu_probe_device() ACPI/IORT: Don't call iommu_ops->add_device directly iommu/of: Don't call iommu_ops->add_device directly iommu: Consolitate ->add/remove_device() calls iommu/sysfs: Rename iommu_release_device() dmaengine: sh: rcar-dmac: Use device_iommu_mapped() xhci: Use device_iommu_mapped() powerpc/iommu: Use device_iommu_mapped() ACPI/IORT: Use device_iommu_mapped() iommu/of: Use device_iommu_mapped() driver core: Introduce device_iommu_mapped() function iommu/tegra: Use helper functions to access dev->iommu_fwspec iommu/qcom: Use helper functions to access dev->iommu_fwspec iommu/of: Use helper functions to access dev->iommu_fwspec iommu/mediatek: Use helper functions to access dev->iommu_fwspec iommu/ipmmu-vmsa: Use helper functions to access dev->iommu_fwspec iommu/dma: Use helper functions to access dev->iommu_fwspec iommu/arm-smmu: Use helper functions to access dev->iommu_fwspec ACPI/IORT: Use helper functions to access dev->iommu_fwspec iommu: Introduce wrappers around dev->iommu_fwspec ...

git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux Pull kgdb updates from Daniel Thompson: "Mostly clean ups although while Doug's was chasing down a odd lockdep warning he also did some work to improved debugger resilience when some CPUs fail to respond to the round up request. The main changes are: - Fixing a lockdep warning on architectures that cannot use an NMI for the round up plus related changes to make CPU round up and all CPU backtrace more resilient. - Constify the arch ops tables - A couple of other small clean ups Two of the three patchsets here include changes that spill over into arch/. Changes in the arch space are relatively narrow in scope (and directly related to kgdb).
