git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI fixes from Rafael Wysocki: "These fix a device enumeration problem related to _ADR matching and an IOMMU initialization issue related to the DMAR table missing, remove an excessive function call from the core ACPI code, update an error message in the ACPI WDAT watchdog driver and add a way to work around problems with unhandled GPE notifications. Specifics: - Fix a device enumeration issue leading to incorrect associations between ACPI device objects and platform device objects representing physical devices if the given device object has both _ADR and _HID (Rafael Wysocki). - Avoid passing NULL to acpi_put_table() during IOMMU initialization which triggers a (rightful) warning from ACPICA (Rafael Wysocki). - Drop an excessive call to acpi_dma_deconfigure() from the core code that binds ACPI device objects to device objects representing physical devices (Lorenzo Pieralisi). - Update an error message in the ACPI WDAT watchdog driver to make it provide more useful information (Mika Westerberg). - Add a mechanism to work around issues with unhandled GPE notifications that occur during system initialization and cannot be prevented by means of sysfs (Lv Zheng)" * tag 'acpi-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / DMAR: Avoid passing NULL to acpi_put_table() ACPI / scan: Prefer devices without _HID/_CID for _ADR matching ACPI / watchdog: Print out error number when device creation fails ACPI / sysfs: Provide quirk mechanism to prevent GPE flooding ACPI: Drop misplaced acpi_dma_deconfigure() call from acpi_bind_one()

2017-01-05ACPI / DMAR: Avoid passing NULL to acpi_put_table()Rafael J. Wysocki
Linus reported that commit 174cc7187e6f "ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel" added a new warning on his desktop system: ACPI Warning: Table ffffffff9fe6c0a0, Validation count is zero before decrement which turns out to come from the acpi_put_table() in detect_intel_iommu(). This happens if the DMAR table is not present in which case NULL is passed to acpi_put_table() which doesn't check against that and attempts to handle it regardless. For this reason, check the pointer passed to acpi_put_table() before invoking it. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Tested-by: Paul E.

2017-01-04net: systemport: Pad packet before inserting TSBFlorian Fainelli
Inserting the TSB means adding an extra 8 bytes in front the of packet that is going to be used as metadata information by the TDMA engine, but stripped off, so it does not really help with the packet padding. For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP) we can end-up padding them after the TSB insertion, thus making them 64 bytes, but with the TDMA stripping off the first 8 bytes, they could still be smaller than 64 bytes which is required to ingress the switch. Fix this by swapping the padding and TSB insertion, guaranteeing that the packets have the right sizes.

2017-01-03benet: stricter vxlan offloading check in be_features_checkSabrina Dubroca
When VXLAN offloading is enabled, be_features_check() tries to check if an encapsulated packet is indeed a VXLAN packet. The check is not strict enough, and considers any UDP-encapsulated ethernet frame with a 8-byte tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE have a 8-byte header, so they get through this check. Force the UDP destination port to be the one that has been offloaded to hardware. Without this, GENEVE-encapsulated packets can end up having an incorrect checksum when both a GENEVE and a VXLAN (offloaded) tunnel are configured.

2017-01-03drm/i915: Force VDD off on the new power seqeuencer before starting to use itVille Syrjälä
Apparently some VLV BIOSen like to leave the VDD force bit enabled even for power seqeuncers that aren't properly hooked up to any port. That will result in a imbalance in the AUX power domain refcount when we stat to use said power sequencer as edp_panel_vdd_on() will not grab the power domain reference if it sees that the VDD is already on. To fix this let's make sure we turn off the VDD force bit when we initialize the power sequencer registers. That is, unless it's being done from the init path since there we are actually initializing the registers for the current power sequencer and we don't want to turn VDD off needlessly as that would require waiting for the power cycle delay before we turn it back on. This fixes the following kind of warnings: WARNING: CPU: 0 PID: 123 at ../drivers/gpu/drm/i915/intel_runtime_pm.c:1455 intel_display_power_put+0x13a/0x170 [i915]() WARN_ON(!power_domains->domain_use_count[domain]) ... v2: Fix typos in comment (David) Cc: stable@vger.kernel.org Cc: Matwey V.

2017-01-02ACPI / scan: Prefer devices without _HID/_CID for _ADR matchingRafael J. Wysocki
The way acpi_find_child_device() works currently is that, if there are two (or more) devices with the same _ADR value in the same namespace scope (which is not specifically allowed by the spec and the OS behavior in that case is not defined), the first one of them found to be present (with the help of _STA) will be returned. This covers the majority of cases, but is not sufficient if some of the devices in question have a _HID (or _CID) returning some valid ACPI/PNP device IDs (which is disallowed by the spec) and the ASL writers' expectation appears to be that the OS will match devices without a valid ACPI/PNP device ID against a given bus address first. To cover this special case as well, modify find_child_checks() to prefer devices without ACPI/PNP device IDs over devices that have them.

While applying patch d443a0aa3a29: "HID: hid-sensor-hub: clear memory to avoid random data", there was some issues in applying correct version of the patch. This resulted in the breakage of sensor functions as all request like power-up will be reset by the memset() in the function sensor_hub_set_feature(). The reset of caller buffer should be in the function sensor_hub_get_feature(), not in the sensor_hub_set_feature().
