2021-12-16soc/tegra: pmc: Add reboot notifierJon Hunter
The Tegra PMC driver implements a restart handler that supports Tegra specific reboot commands such as placing the device into 'recovery' mode in order to reprogram the platform. This is accomplished by setting the appropriate bit in the PMC scratch0 register prior to rebooting the platform. For Tegra platforms that support PSCI or EFI, the default Tegra restart handler is not called and the PSCI or EFI restart handler is called instead. Hence, for Tegra platforms that support PSCI or EFI, the Tegra specific reboot commands do not currently work. Fix this by moving the code that programs the PMC scratch0 register into a separate reboot notifier that will always be called on reboot.

2021-12-16arm64: dts: imx8mp-evk: configure multiple queues on eqosXiaoliang Yang
Eqos ethernet support five queues on hardware, enable these queues and configure the priority of each queue. Uses Strict Priority as scheduling algorithms to ensure that the TSN function works. The priority of each queue is a bitmask value that maps VLAN tag priority to the queue. Since the hardware only supports five queues, this patch maps priority 0-4 to queues one by one, and priority 5-7 to queue 4. The total fifo size of 5 queues is 8192 bytes, if enable 5 queues with store-and-forward mode, it's not enough for large packets, which would trigger fifo overflow frequently. This patch set DMA to thresh mode to enable all 5 queues.

Add overlays for various serdes protocols on LS1028A QDS board using different PHY cards. These should be applied at boot, based on serdes configuration. If no overlay is applied, only the RGMII interface on the QDS is available in Linux. Building device tree fragments requires passing the "-@" argument to dtc, which increases the base dtb size and might cause some platforms to fail to store the new binary. To avoid that, it would be nice to only pass "-@" for the platforms where fragments will be used, aka LS1028A-QDS.

2021-12-16tee: handle lookup of shm with reference count 0Jens Wiklander
Since the tee subsystem does not keep a strong reference to its idle shared memory buffers, it races with other threads that try to destroy a shared memory through a close of its dma-buf fd or by unmapping the memory. In tee_shm_get_from_id() when a lookup in teedev->idr has been successful, it is possible that the tee_shm is in the dma-buf teardown path, but that path is blocked by the teedev mutex. Since we don't have an API to tell if the tee_shm is in the dma-buf teardown path or not we must find another way of detecting this condition. Fix this by doing the reference counting directly on the tee_shm using a new refcount_t refcount field. dma-buf is replaced by using anon_inode_getfd() instead, this separates the life-cycle of the underlying file from the tee_shm. tee_shm_put() is updated to hold the mutex when decreasing the refcount to 0 and then remove the tee_shm from teedev->idr before releasing the mutex. This means that the tee_shm can never be found unless it has a refcount larger than 0.

2021-12-16xen/netback: don't queue unlimited number of packagesJuergen Gross
In case a guest isn't consuming incoming network traffic as fast as it is coming in, xen-netback is buffering network packages in unlimited numbers today. This can result in host OOM situations. Commit f48da8b14d04ca8 ("xen-netback: fix unlimited guest Rx internal queue and carrier flapping") meant to introduce a mechanism to limit the amount of buffered data by stopping the Tx queue when reaching the data limit, but this doesn't work for cases like UDP. When hitting the limit don't queue further SKBs, but drop them instead. In order to be able to tell Rx packages have been dropped increment the rx_dropped statistics counter in this case. It should be noted that the old solution to continue queueing SKBs had the additional problem of an overflow of the 32-bit rx_queue_len value would result in intermittent Tx queue enabling.
