The omapfb driver fails to build after commit 23c35f48f5fb ("pinctrl: remove include file from <linux/device.h>") because it relies on the <linux/pinctrl/consumer.h> and <linux/seq_file.h> being pulled in by the <linux/device.h> header implicitly.

2018-02-08platform/x86: mlx-platform: Fix power cable setting for msn21xx familyVadim Pasternak
Add dedicated structure with power cable setting for Mellanox msn21xx family. These systems do not have a physical device for the power unit controller. When the power cable is inserted or removed, the relevant interrupt signal is handled, the status is updated, but no device is associated with the signal. Add definition for interrupt low aggregation signal. On system from msn21xx family, low aggregation mask should be removed in order to allow signal to hit CPU.

2018-02-08net: thunder: change q_len's type to handle max ring sizeDean Nelson
The Cavium thunder nicvf driver supports rx/tx rings of up to 65536 entries per. The number of entires are stored in the q_len member of struct q_desc_mem. The problem is that q_len being a u16, results in 65536 becoming 0. In getting pointers to descriptors in the rings, the driver uses q_len minus 1 as a mask after incrementing the pointer, in order to go back to the beginning and not go past the end of the ring. With the q_len set to 0 the mask is no longer correct and the driver does go beyond the end of the ring, causing various ills. Usually the first thing that shows up is a "NETDEV WATCHDOG: enP2p1s0f1 (nicvf): transmit queue 7 timed out" warning. This patch remedies the problem by changing q_len to a u32.

2018-02-08tuntap: add missing xdp flushJason Wang
When using devmap to redirect packets between interfaces, xdp_do_flush() is usually a must to flush any batched packets. Unfortunately this is missed in current tuntap implementation. Unlike most hardware driver which did XDP inside NAPI loop and call xdp_do_flush() at then end of each round of poll. TAP did it in the context of process e.g tun_get_user(). So fix this by count the pending redirected packets and flush when it exceeds NAPI_POLL_WEIGHT or MSG_MORE was cleared by sendmsg() caller.

2018-02-08nfp: don't advertise hw-tc-offload on non-port netdevsJakub Kicinski
nfp_port is a structure which represents an ASIC port, both PCIe vNIC (on a PF or a VF) or the external MAC port. vNIC netdev (struct nfp_net) and pure representor netdev (struct nfp_repr) both have a pointer to this structure. nfp_reprs always have a port associated. nfp_nets, however, only represent a device port in legacy mode, where they are considered the MAC port. In switchdev mode they are just the CPU's side of the PCIe link. By definition TC offloads only apply to device ports. Don't set the flag on vNICs without a port (i.e. in switchdev mode).

2018-02-08cpufreq: intel_pstate: Enable HWP during system resume on CPU0Chen Yu
When maxcpus=1 is in the kernel command line, the BP is responsible for re-enabling the HWP - because currently only the APs invoke intel_pstate_hwp_enable() during their online process - which might put the system into unstable state after resume. Fix this by enabling the HWP explicitly on BP during resume.

2018-02-07net: ethernet: ti: cpsw: fix net watchdog timeoutGrygorii Strashko
It was discovered that simple program which indefinitely sends 200b UDP packets and runs on TI AM574x SoC (SMP) under RT Kernel triggers network watchdog timeout in TI CPSW driver (<6 hours run). The network watchdog timeout is triggered due to race between cpsw_ndo_start_xmit() and cpsw_tx_handler() [NAPI] cpsw_ndo_start_xmit() if (unlikely(!cpdma_check_free_tx_desc(txch))) { txq = netdev_get_tx_queue(ndev, q_idx); netif_tx_stop_queue(txq); ^^ as per [1] barier has to be used after set_bit() otherwise new value might not be visible to other cpus } cpsw_tx_handler() if (unlikely(netif_tx_queue_stopped(txq))) netif_tx_wake_queue(txq); and when it happens ndev TX queue became disabled forever while driver's HW TX queue is empty. Fix this, by adding smp_mb__after_atomic() after netif_tx_stop_queue() calls and double check for free TX descriptors after stopping ndev TX queue - if there are free TX descriptors wake up ndev TX queue.

At some point, a check was added to exit the polling routine during resets.

This patch checks if we are performing a non-fatal reset and if we are, continues normal polling operation. Signed-off-by: John Allen <jallen@linux.vnet.ibm.com> Signed-off-by: David S.

back-end device sdm has already attached a cache_set with ID f67ebe1f-f8bc-4d73-bfe5-9dc88607f119, then try to attach with another cache set, and it returns with an error: [root]# cd /sys/block/sdm/bcache [root]# echo 5ccd0a63-148e-48b8-afa2-aca9cbd6279f > attach -bash: echo: write error: Invalid argument After that, execute a command to modify the label of bcache device: [root]# echo data_disk1 > label Then we reboot the system, when the system power on, the back-end device can not attach to cache_set, a messages show in the log: Feb 5 12:05:52 ceph152 kernel: [922385.508498] bcache: bch_cached_dev_attach() couldn't find uuid for sdm in set In sysfs_attach(), dc->sb.set_uuid was assigned to the value which input through sysfs, no matter whether it is success or not in bch_cached_dev_attach(). For example, If the back-end device has already attached to an cache set, bch_cached_dev_attach() would fail, but dc->sb.set_uuid was changed. Then modify the label of bcache device, it will call bch_write_bdev_super(), which would write the dc->sb.set_uuid to the super block, so we record a wrong cache set ID in the super block, after the system reboot, the cache set couldn't find the uuid of the back-end device, so the bcache device couldn't exist and use any more. In this patch, we don't assigned cache set ID to dc->sb.set_uuid in sysfs_attach() directly, but input it into bch_cached_dev_attach(), and assigned dc->sb.set_uuid to the cache set ID after the back-end device attached to the cache set successful.
