As there are incorrect assumptions in which some of the initialization and data path flows cannot sleep, most allocations are being done using GFP_ATOMIC. We modify the code to use GFP_ATOMIC only when realy needed, as sleepable flow should use GFP_KERNEL. In addition add a fallback to allocate memory using GFP_KERNEL, once ATOMIC allocation fails.

2021-04-08libnvdimm: Notify disk drivers to revalidate region read-onlyDan Williams
Previous kernels allowed the BLKROSET to override the disk's read-only status. With that situation fixed the pmem driver needs to rely on notification events to reevaluate the disk read-only status after the host region has been marked read-write. Recall that when libnvdimm determines that the persistent memory has lost persistence (for example lack of energy to flush from DRAM to FLASH on an NVDIMM-N device) it marks the region read-only, but that state can be overridden by the user via: echo 0 > /sys/bus/nd/devices/regionX/read_only ...to date there is no notification that the region has restored persistence, so the user override is the only recovery.

2021-04-08net: dsa: lantiq_gswip: Configure all remaining GSWIP_MII_CFG bitsMartin Blumenstingl
There are a few more bits in the GSWIP_MII_CFG register for which we did rely on the boot-loader (or the hardware defaults) to set them up properly. For some external RMII PHYs we need to select the GSWIP_MII_CFG_RMII_CLK bit and also we should un-set it for non-RMII PHYs. The GSWIP_MII_CFG_RMII_CLK bit is ignored for other PHY connection modes. The GSWIP IP also supports in-band auto-negotiation for RGMII PHYs when the GSWIP_MII_CFG_RGMII_IBS bit is set. Clear this bit always as there's no known hardware which uses this (so it is not tested yet). Clear the xMII isolation bit when set at initialization time if it was previously set by the bootloader. Not doing so could lead to no traffic (neither RX nor TX) on a port with this bit set. While here, also add the GSWIP_MII_CFG_RESET bit. We don't need to manage it because this bit is self-clearning when set. We still add it here to get a better overview of the GSWIP_MII_CFG register.

2021-04-08net: dsa: lantiq_gswip: Don't use PHY auto pollingMartin Blumenstingl
PHY auto polling on the GSWIP hardware can be used so link changes (speed, link up/down, etc.) can be detected automatically. Internally GSWIP reads the PHY's registers for this functionality. Based on this automatic detection GSWIP can also automatically re-configure it's port settings. Unfortunately this auto polling (and configuration) mechanism seems to cause various issues observed by different people on different devices: - FritzBox 7360v2: the two Gbit/s ports (connected to the two internal PHY11G instances) are working fine but the two Fast Ethernet ports (using an AR8030 RMII PHY) are completely dead (neither RX nor TX are received). It turns out that the AR8030 PHY sets the BMSR_ESTATEN bit as well as the ESTATUS_1000_TFULL and ESTATUS_1000_XFULL bits. This makes the PHY auto polling state machine (rightfully?) think that the established link speed (when the other side is Gbit/s capable) is 1Gbit/s. - None of the Ethernet ports on the Zyxel P-2812HNU-F1 (two are connected to the internal PHY11G GPHYs while the other three are external RGMII PHYs) are working. Neither RX nor TX traffic was observed. It is not clear which part of the PHY auto polling state- machine caused this. - FritzBox 7412 (only one LAN port which is connected to one of the internal GPHYs running in PHY22F / Fast Ethernet mode) was seeing random disconnects (link down events could be seen). Sometimes all traffic would stop after such disconnect. It is not clear which part of the PHY auto polling state-machine cauased this. - TP-Link TD-W9980 (two ports are connected to the internal GPHYs running in PHY11G / Gbit/s mode, the other two are external RGMII PHYs) was affected by similar issues as the FritzBox 7412 just without the "link down" events Switch to software based configuration instead of PHY auto polling (and letting the GSWIP hardware configure the ports automatically) for the following link parameters: - link up/down - link speed - full/half duplex - flow control (RX / TX pause) After a big round of manual testing by various people (who helped test this on OpenWrt) it turns out that this fixes all reported issues. Additionally it can be considered more future proof because any "quirk" which is implemented for a PHY on the driver side can now be used with the GSWIP hardware as well because Linux is in control of the link parameters. As a nice side-effect this also solves a problem where fixed-links were not supported previously because we were relying on the PHY auto polling mechanism, which cannot work for fixed-links as there's no PHY from where it can read the registers. Configuring the link settings on the GSWIP ports means that we now use the settings from device-tree also for ports with fixed-links.

2021-04-08ice: fix memory leak of aRFS after resuming from suspendYongxin Liu
In ice_suspend(), ice_clear_interrupt_scheme() is called, and then irq_free_descs() will be eventually called to free irq and its descriptor. In ice_resume(), ice_init_interrupt_scheme() is called to allocate new irqs. However, in ice_rebuild_arfs(), struct irq_glue and struct cpu_rmap maybe cannot be freed, if the irqs that released in ice_suspend() were reassigned to other devices, which makes irq descriptor's affinity_notify lost. So call ice_free_cpu_rx_rmap() before ice_clear_interrupt_scheme(), which can make sure all irq_glue and cpu_rmap can be correctly released before corresponding irq and descriptor are released.

2021-04-08clocksource/drivers/timer-ti-dm: Handle dra7 timer wrap errata i940Tony Lindgren
There is a timer wrap issue on dra7 for the ARM architected timer. In a typical clock configuration the timer fails to wrap after 388 days. To work around the issue, we need to use timer-ti-dm percpu timers instead. Let's configure dmtimer3 and 4 as percpu timers by default, and warn about the issue if the dtb is not configured properly. Let's do this as a single patch so it can be backported to v5.8 and later kernels easily. Note that this patch depends on earlier timer-ti-dm systimer posted mode fixes, and a preparatory clockevent patch "clocksource/drivers/timer-ti-dm: Prepare to handle dra7 timer wrap issue". For more information, please see the errata for "AM572x Sitara Processors Silicon Revisions 1.1, 2.0": https://www.ti.com/lit/er/sprz429m/sprz429m.pdf The concept is based on earlier reference patches done by Tero Kristo and Keerthy.
