2020-12-19rtc: pcf2127: only use watchdog when explicitly availableUwe Kleine-König1-1/+2
Most boards using the pcf2127 chip (in my bubble) don't make use of the watchdog functionality and the respective output is not connected. The effect on such a board is that there is a watchdog device provided that doesn't work. So only register the watchdog if the device tree has a "reset-source" property.

2020-12-19dt-bindings: rtc: add reset-source propertyRasmus Villemoes1-0/+5
Some RTCs, e.g. the pcf2127, can be used as a hardware watchdog. But if the reset pin is not actually wired up, the driver exposes a watchdog device that doesn't actually work. Provide a standard binding that can be used to indicate that a given RTC can perform a reset of the machine, similar to wakeup-source.

2020-12-18net/sched: sch_taprio: ensure to reset/destroy all child qdiscsDavide Caratti1-3/+4
taprio_graft() can insert a NULL element in the array of child qdiscs. As a consquence, taprio_reset() might not reset child qdiscs completely, and taprio_destroy() might leak resources. Fix it by ensuring that loops that iterate over q->qdiscs[] don't end when they find the first NULL item.

'pci_set_dma_mask()' + 'pci_set_consistent_dma_mask()' can be replaced by an equivalent 'dma_set_mask_and_coherent()' which is much less verbose.

2020-12-18virtio-mem: Big Block Mode (BBM) - safe memory hotunplugDavid Hildenbrand1-2/+95
Let's add a safe mechanism to unplug memory, avoiding long/endless loops when trying to offline memory - similar to in SBM. Fake-offline all memory (via alloc_contig_range()) before trying to offline+remove it. Use this mode as default, but allow to enable the other mode explicitly (which could give better memory hotunplug guarantees in some environments). The "unsafe" mode can be enabled e.g., via virtio_mem.bbm_safe_unplug=0 on the cmdline. Reviewed-by: Wei Yang <[email protected]> Cc: "Michael S.
