[ upstream commit 21f96522 ] If an SQPOLL based ring is newly created and an application issues an io_uring_enter(2) system call on it, then we can return a spurious -EOWNERDEAD error. This happens because there's nothing to submit, and if the caller doesn't specify any other action, the initial error assignment of -EOWNERDEAD never gets overwritten. This causes us to return it directly, even if it isn't valid. Move the error assignment into the actual failure case instead.

[ Upstream commit f56ce412 ] We've noticed occasional OOM killing when memory.low settings are in effect for cgroups. This is unexpected and undesirable as memory.low is supposed to express non-OOMing memory priorities between cgroups. The reason for this is proportional memory.low reclaim. When cgroups are below their memory.low threshold, reclaim passes them over in the first round, and then retries if it couldn't find pages anywhere else. But when cgroups are slightly above their memory.low setting, page scan force is scaled down and diminished in proportion to the overage, to the point where it can cause reclaim to fail as well - only in that case we currently don't retry, and instead trigger OOM. To fix this, hook proportional reclaim into the same retry logic we have in place for when cgroups are skipped entirely. This way if reclaim fails and some cgroups were scanned with diminished pressure, we'll try another full-force cycle before giving up and OOMing.

[ Upstream commit 65ca89c2 ] The commit 2e6b8363 ("ASoC: intel: atom: Fix reference to PCM buffer address") changed the reference of PCM buffer address to substream->runtime->dma_addr as the buffer address may change dynamically. However, I forgot that the dma_addr field is still not set up for the CONTINUOUS buffer type (that this driver uses) yet in 5.14 and earlier kernels, and it resulted in garbage I/O. The problem will be fixed in 5.15, but we need to address it quickly for now. The fix is to deduce the address again from the DMA pointer with virt_to_phys(), but from the right one, substream->runtime->dma_area.

[ Upstream commit 2a671f77 ] The struct pci_dev uses reference counting but zPCI assumed erroneously that the last reference would always be the local reference after calling pci_stop_and_remove_bus_device(). This is usually the case but not how reference counting works and thus inherently fragile. In fact one case where this causes a NULL pointer dereference when on an SRIOV device the function 0 was hot unplugged before another function of the same multi-function device. In this case the second function's pdev->sriov->dev reference keeps the struct pci_dev of function 0 alive even after the unplug. This bug was previously hidden by the fact that we were leaking the struct pci_dev which in turn means that it always outlived the struct zpci_dev. This was fixed in commit 0b13525c ("s390/pci: fix leak of PCI device structure") exposing the broken behavior. Fix this by accounting for the long living reference a struct pci_dev has to its underlying struct zpci_dev via the zbus->function[] array and only release that in pcibios_release_device() ensuring that the struct pci_dev is not left with a dangling reference. This is a minimal fix in the future it would probably better to use fine grained reference counting for struct zpci_dev.

So set 200 kHz as the minimum clock frequency available for that board.

[ Upstream commit 9711759a ] As GDSCs are registered and found to be already enabled gdsc_init() ensures that 1) the kernel state matches the hardware state, and 2) votable GDSCs are properly enabled from this master as well. But as the (optional) supply regulator is enabled deep into gdsc_toggle_logic(), which is only executed for votable GDSCs, the kernel's state of the regulator might not match the hardware. The regulator might be automatically turned off if no other users are present or the next call to gdsc_disable() would cause an unbalanced regulator_disable(). Given that the votable case deals with an already enabled GDSC, most of gdsc_enable() and gdsc_toggle_logic() can be skipped. Reduce it to just clearing the SW_COLLAPSE_MASK and enabling hardware control to simply call regulator_enable() in both cases. The enablement of hardware control seems to be an independent property from the GDSC being enabled, so this is moved outside that conditional segment. Lastly, as the propagation of ALWAYS_ON to GENPD_FLAG_ALWAYS_ON needs to happen regardless of the initial state this is grouped together with the other sc->pd updates at the end of the function.

[ Upstream commit 25f8203b ] When a Data CRC interrupt is received, the driver disables the DMA, then sends the stop/abort command and then waits for Data Transfer Over. However, sometimes, when a data CRC error is received in the middle of a multi-block write transfer, the Data Transfer Over interrupt is never received, and the driver hangs and never completes the request. The driver sets the BMOD.SWR bit (SDMMC_IDMAC_SWRESET) when stopping the DMA, but according to the manual CMD.STOP_ABORT_CMD should be programmed "before assertion of SWR". Do these operations in the recommended order. With this change the Data Transfer Over is always received correctly in my tests. Signed-off-by:

[ Upstream commit a222be59 ] Without this patch, ATR does not work. Receive/transmit uses queue selection based on SW DCB hashing method. If traffic classes are not configured for PF, then use netdev_pick_tx function for selecting queue for packet transmission. Instead of calling i40e_swdcb_skb_tx_hash, call netdev_pick_tx, which ensures that packet is transmitted/received from CPU that is running the application. Reproduction steps: 1. Load i40e driver 2. Map each MSI interrupt of i40e port for each CPU 3. Disable ntuple, enable ATR i.e.: ethtool -K $interface ntuple off ethtool --set-priv-flags $interface flow-director-atr 4. Run application that is generating traffic and is bound to a single CPU, i.e.: taskset -c 9 netperf -H 1.1.1.1 -t TCP_RR -l 10 5.

[ Upstream commit 7bd0cef5 ] When registering mdiobus children, if we get an -EPROBE_DEFER, we shouldn't ignore it and continue registering the rest of the mdiobus children. This would permanently prevent the deferring child mdiobus from working instead of reattempting it in the future. So, if a child mdiobus needs to be reattempted in the future, defer the entire mdio-mux initialization.

[ Upstream commit dbcf24d1 ] Commit a02e8964 ("virtio-net: ethtool configurable LRO") maps LRO to virtio guest offloading features and allows the administrator to enable and disable those features via ethtool. This leads to several issues: - For a device that doesn't support control guest offloads, the "LRO" can't be disabled triggering WARN in dev_disable_lro() when turning off LRO or when enabling forwarding bridging etc. - For a device that supports control guest offloads, the guest offloads are disabled in cases of bridging, forwarding etc slowing down the traffic. Fix this by using NETIF_F_GRO_HW instead. Though the spec does not guarantee packets to be re-segmented as the original ones, we can add that to the spec, possibly with a flag for devices to differentiate between GRO and LRO. Further, we never advertised LRO historically before a02e8964 ("virtio-net: ethtool configurable LRO") and so bridged/forwarded configs effectively always relied on virtio receive offloads behaving like GRO - thus even if this breaks any configs it is at least not a regression.

[ Upstream commit 97c2c69e ] The number of queues implemented by many virtio backends is limited, especially some machines have a large number of CPUs. In this case, it is often impossible to allocate a separate queue for XDP_TX/XDP_REDIRECT, then xdp cannot be loaded to work, even xdp does not use the XDP_TX/XDP_REDIRECT. This patch allows XDP_TX/XDP_REDIRECT to run by reuse the existing SQ with __netif_tx_lock() hold when there are not enough queues. Signed-off-by:
