2016-08-01virtio: new feature to detect IOMMU device quirkMichael S. Tsirkin
The interaction between virtio and IOMMUs is messy. On most systems with virtio, physical addresses match bus addresses, and it doesn't particularly matter which one we use to program the device. On some systems, including Xen and any system with a physical device that speaks virtio behind a physical IOMMU, we must program the IOMMU for virtio DMA to work at all. On other systems, including SPARC and PPC64, virtio-pci devices are enumerated as though they are behind an IOMMU, but the virtio host ignores the IOMMU, so we must either pretend that the IOMMU isn't there or somehow map everything as the identity. Add a feature bit to detect that quirk: VIRTIO_F_IOMMU_PLATFORM. Any device with this feature bit set to 0 needs a quirk and has to be passed physical addresses (as opposed to bus addresses) even though the device is behind an IOMMU. Note: it has to be a per-device quirk because for example, there could be a mix of passed-through and virtual virtio devices. As another example, some devices could be implemented by an out of process hypervisor backend (in case of qemu vhost, or vhost-user) and so support for an IOMMU needs to be coded up separately. It would be cleanest to handle this in IOMMU core code, but that needs per-device DMA ops. While we are waiting for that to be implemented, use a work-around in virtio core. Note: a "noiommu" feature is a quirk - add a wrapper to make that clear. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2016-08-01balloon: check the number of available pages in leak balloonKonstantin Neumoin
The balloon has a special mechanism that is subscribed to the oom notification which leads to deflation for a fixed number of pages. The number is always fixed even when the balloon is fully deflated. But leak_balloon did not expect that the pages to deflate will be more than taken, and raise a "BUG" in balloon_page_dequeue when page list will be empty. So, the simplest solution would be to check that the number of releases pages is less or equal to the number taken pages.

In 4.7-rc1 we introduced auto-probing for the ACPI DSM (device- specific-method) format that the platform firmware implements for nvdimm devices. We initially fixed a regression in probing the QEMU DSM implementation by making acpi_check_dsm() tolerant of the way QEMU reports the "0 DSMs supported" condition. However, that broke HPE platforms since that tolerance caused the driver to mistakenly match the 1-zero-byte response those platforms give to "unknown" commands. Instead, we simply make the driver tolerant of not finding any supported DSMs. This has been tested to work with both QEMU and HPE platforms.

2016-07-22gpio: tegra: don't auto-enable for COMPILE_TESTArnd Bergmann
I stumbled over a build error with COMPILE_TEST and CONFIG_OF disabled: drivers/gpio/gpio-tegra.c: In function 'tegra_gpio_probe': drivers/gpio/gpio-tegra.c:603:9: error: 'struct gpio_chip' has no member named 'of_node' The problem is that the newly added GPIO_TEGRA Kconfig symbol does not have a dependency on CONFIG_OF. However, there is another problem here as the driver gets enabled unconditionally whenever COMPILE_TEST is set. This fixes both problems, by making the symbol user-visible when COMPILE_TEST is set and default-enabled for ARCH_TEGRA=y. As a side-effect, it is now possible to compile-test a Tegra kernel with GPIO support disabled, which is harmless.

The size of individual keymap in drivers/tty/vt/keyboard.c is NR_KEYS, which is currently 256, whereas number of keys/buttons in input device (and therefor in key_down) is much larger - KEY_CNT - 768, and that can cause out-of-bound access when we do sym = U(key_maps[0][k]); with large 'k'. To fix it we should not attempt iterating beyond smaller of NR_KEYS and KEY_CNT. Also while at it let's switch to for_each_set_bit() instead of open-coding it.

This patch fixes the lost of Ethernet port on low memory system, when driver frees its resources and fails to allocate new resources. Issue could happen while changing number of channels, rings size or changing the timestamp configuration. This fix is necessary because of removing vmap use in the code. When vmap was in use driver could allocate non-contiguous memory and make it contiguous with vmap. Now it could fail to allocate a large chunk of contiguous memory and lose the port. Current code tries to allocate new resources and then upon success frees the old resources.

Commit 4995734e973a "acpi, nfit: fix acpi_check_dsm() vs zero functions implemented" attempted to fix a QEMU regression by supporting its usage of a zero-mask as a valid response to a DSM-family probe request. However, this behavior breaks HP platforms that return a zero-mask by default causing the probe to misidentify the DSM-family. Instead, the QEMU regression can be fixed by simply not requiring the DSM family to be identified. This effectively reverts commit 4995734e973a, and removes the DSM requirement from the init path.

2016-07-18drm/i915: add missing condition for committing planes on crtcLionel Landwerlin
The i915 driver checks for color management properties changes as part of a plane update. Therefore a color management update must imply a plane update, otherwise we never update the transformation matrixes and degamma/gamma LUTs. v2: add comment about moving the commit of color management registers to an async worker v3: Commit color management register right after vblank v4: Move back color management commit condition together with planes commit v5: Trigger color management commit through the planes commit (Daniel) v6: Make plane change update more readable Fixes: 20a34e78f0d7 (drm/i915: Update color management during vblank evasion.)

2016-07-18drm/i915: Treat eDP as always connected, againVille Syrjälä
eDP should be treated as connected even if doesn't have an EDID. In that case we'll use the timings from the VBT. That used to be the case until commit f21a21983ef1 ("drm/i915: Splitting intel_dp_detect") broke things by considering even eDP disconnected if we fail to get an EDID for it. Fix things up again by treating eDP as always connected.

2016-07-18mmc: pxamci: fix potential oopsRobert Jarzmik
As reported by Dan in his report in [1], there is a potential NULL pointer derefence if these conditions are met : - there is no platform_data provided, ie. host->pdata = NULL Fix this by only using the platform data ro_invert when a gpio for read-only is provided by the platform data. This doesn't appear yet as every pxa board provides a platform_data, and calls pxa_set_mci_info() with a non NULL pointer. [1] [bug report] mmc: pxamci: fix card detect with slot-gpio API. The commit fd546ee6a7dc ("mmc: pxamci: fix card detect with slot-gpio API") from Sep 26, 2015, leads to the following static checker warning: drivers/mmc/host/pxamci.c:809 pxamci_probe() warn: variable dereferenced before check 'host->pdata' (see line 798) Fixes: fd546ee6a7dc ("mmc: pxamci: fix card detect with slot-gpio API") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2016-07-16net: cavium: liquidio: Avoid dma_unmap_single on uninitialized ndataFlorian Fainelli
The label lio_xmit_failed is used 3 times through liquidio_xmit() but it always makes a call to dma_unmap_single() using potentially uninitialized variables from "ndata" variable. Out of the 3 gotos, 2 run after ndata has been initialized, and had a prior dma_map_single() call. Fix this by adding a new error label: lio_xmit_dma_failed which does this dma_unmap_single() and then processed with the lio_xmit_failed fallthrough.

2016-07-15mlxsw: spectrum: Prevent invalid ingress buffer mappingIdo Schimmel
Packets entering the switch are mapped to a Switch Priority (SP) according to their PCP value (untagged frames are mapped to SP 0). The packets are classified to a priority group (PG) buffer in the port's headroom according to their SP. The switch maintains another mapping (SP to IEEE priority), which is used to generate PFC frames for lossless PGs. This mapping is initialized to IEEE = SP % 8. Therefore, when mapping SP 'x' to PG 'y' we create a situation in which an IEEE priority is mapped to two different PGs: IEEE 'x' ---> SP 'x' ---> PG 'y' IEEE 'x' ---> SP 'x + 8' ---> PG '0' (default) Which is invalid, as a flow can use only one PG buffer. Fix this by mapping both SP 'x' and 'x + 8' to the same PG buffer.

When setting a new speed we need to disable and enable the port for the changes to take effect. We currently only do that if the operational state of the port is up. However, setting a new speed following link training failure will require us to explicitly set the port down and then up. Instead, disable and enable the port based on its administrative state.
