Most of these are relatively unimportant fixes for regressions introduced during the merge window, and about half of the changes are for mach-omap2.

Notable fixes include: - removing the skeleton.dtsi include broke a number of machines, and we have to put empty /chosen nodes back to be able to pass kernel command lines as before - enabling Samsung platforms no longer hardwires CONFIG_HZ to 200, as it had been for no good reason for a long time" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (46 commits) MAINTAINERS: extend PSCI entry to cover the newly add PSCI checker code drivers: psci: annotate timer on stack to silence odebug messages ARM64: defconfig: enable DRM_MESON as module ARM64: dts: meson-gx: Add Graphic Controller nodes ARM64: dts: meson-gxl: fix GPIO include ARM: dts: imx6: Disable "weim" node in the dtsi files ARM: dts: qcom: apq8064: Add missing scm clock ARM: davinci: da8xx: Fix sleeping function called from invalid context ARM: davinci: Make __clk_{enable,disable} functions public ARM: davinci: da850: don't add emac clock to lookup table twice ARM: davinci: da850: fix infinite loop in clk_set_rate() ARM: i.MX: remove map_io callback ARM: dts: vf610-zii-dev-rev-b: Add missing newline ARM: dts: imx6qdl-nitrogen6x: remove duplicate iomux entry ARM: dts: imx31: fix AVIC base address ARM: dts: am572x-idk: Add gpios property to control PCIE_RESETn arm64: dts: vexpress: Support GICC_DIR operations ARM: dts: vexpress: Support GICC_DIR operations firmware: arm_scpi: fix reading sensor values on pre-1.0 SCPI firmwares arm64: dts: msm8996: Add required memory carveouts ...

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. This is similar to commit a547224dceed ("mlx4e: Do not attempt to offload VXLAN ports that are unrecognized"). Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2016-12-30firmware: arm_scpi: fix reading sensor values on pre-1.0 SCPI firmwaresMartin Blumenstingl
The pre-1.0 SCPI firmwares are using single __le32 as sensor value, while the SCPI v1.0 protocol uses two __le32 as sensor values(64bit) split into 32bit upper and 32bit lower value. Using an "struct sensor_value" to read the sensor value on a pre-1.0 SCPI firmware gives garbage in the "hi_val" field.

2016-12-29net/mlx4_core: Fix raw qp flow steering rules under SRIOVJack Morgenstein
Demoting simple flow steering rule priority (for DPDK) was achieved by wrapping FW commands MLX4_QP_FLOW_STEERING_ATTACH/DETACH for the PF as well, and forcing the priority to MLX4_DOMAIN_NIC in the wrapper function for the PF and all VFs. In function mlx4_ib_create_flow(), this change caused the main rule creation for the PF to be wrapped, while it left the associated tunnel steering rule creation unwrapped for the PF. This mismatch caused rule deletion failures in mlx4_ib_destroy_flow() for the PF when the detach wrapper function did not find the associated tunnel-steering rule (since creation of that rule for the PF did not go through the wrapper function). Fix this by setting MLX4_QP_FLOW_STEERING_ATTACH/DETACH to be "native" (so that the PF invocation does not go through the wrapper), and perform the required priority demotion for the PF in the mlx4_ib_create_flow() code path.

2016-12-29net/mlx4_core: Use-after-free causes a resource leak in flow-steering detachJack Morgenstein
mlx4_QP_FLOW_STEERING_DETACH_wrapper first removes the steering rule (which results in freeing the rule structure), and then references a field in this struct (the qp number) when releasing the busy-status on the rule's qp. Since this memory was freed, it could reallocated and changed. Therefore, the qp number in the struct may be incorrect, so that we are releasing the incorrect qp. This leaves the rule's qp in the busy state (and could possibly release an incorrect qp as well). Fix this by saving the qp number in a local variable, for use after removing the steering rule.

2016-12-28net/mlx5e: Disable netdev after closeSaeed Mahameed

2016-12-28net/mlx5e: Don't sync netdev state when not registeredSaeed Mahameed
Skip setting netdev vxlan ports and netdev rx_mode on driver load when netdev is not yet registered. Synchronizing with netdev state is needed only on reset flow where the netdev remains registered for the whole reset period. This also fixes an access before initialization of net_device.addr_list_lock - which for some reason initialized on register_netdev - where we queued set_rx_mode work on driver load before netdev registration.

This reverts commit 9c7262399ba12825f3ca4b00a76d8d5e77c720f5. PCIe counters were introduced in a new firmware version, as a result users with old firmware encountered a syndrome every 200ms due to update stats work. This feature will be re-introduced later with appropriate capabilities infrastructure.

2016-12-28net/mlx5: Disable RoCE on the e-switch management port under switchdev modeOr Gerlitz
Under the switchdev/offloads mode, packets that don't match any e-switch steering rule are sent towards the e-switch management port. We use a NIC HW steering rule set per vport (uplink and VFs) to make them be received into the host OS through the respective vport representor netdevice. Currnetly such missed RoCE packets will not get to this NIC steering rule, and hence VF RoCE will not work over the slow path of the offloads mode. This is b/c these packets will be matched by a steering rule added by the firmware that serves RoCE traffic set on the PF NIC vport which is also the e-switch management port under SRIOV. Disabling RoCE on the e-switch management vport when we are in the offloads mode, will signal to the firmware to remove their RoCE rule, and then the missed RoCE packets will be matched by the representor NIC steering rule as any other missed packets. To achieve that, we disable RoCE on the PF vport. We do that by removing (hot-unplugging) the IB device instance associated with the PF. This is also required by our current model where the PF serves as the uplink representor and hence only SW switching (TC, bridge, OVS) applications and slow path vport mlx5e net-device should be running over that vport.
