2020-02-25bootconfig: Fix CONFIG_BOOTTIME_TRACING dependency issueMasami Hiramatsu
Since commit d8a953ddde5e ("bootconfig: Set CONFIG_BOOT_CONFIG=n by default") also changed the CONFIG_BOOTTIME_TRACING to select CONFIG_BOOT_CONFIG to show the boot-time tracing on the menu, it introduced wrong dependencies with BLK_DEV_INITRD as below.

2020-02-25drm/panfrost: Add support for multiple power domainsNicolas Boichat
When there is a single power domain per device, the core will ensure the power domain is switched on (so it is technically equivalent to having not power domain specified at all). However, when there are multiple domains, as in MT8183 Bifrost GPU, we need to handle them in driver code.

2020-02-25icmp: allow icmpv6_ndo_send to work with CONFIG_IPV6=nJason A. Donenfeld
The icmpv6_send function has long had a static inline implementation with an empty body for CONFIG_IPV6=n, so that code calling it doesn't need to be ifdef'd. The new icmpv6_ndo_send function, which is intended for drivers as a drop-in replacement with an identical function signature, should follow the same pattern. Without this patch, drivers that used to work with CONFIG_IPV6=n now result in a linker error.

2020-02-25dm integrity: fix a deadlock due to offloading to an incorrect workqueueMikulas Patocka
If we need to perform synchronous I/O in dm_integrity_map_continue(), we must make sure that we are not in the map function - in order to avoid the deadlock due to bio queuing in generic_make_request. To avoid the deadlock, we offload the request to metadata_wq. However, metadata_wq also processes metadata updates for write requests. If there are too many requests that get offloaded to metadata_wq at the beginning of dm_integrity_map_continue, the workqueue metadata_wq becomes clogged and the system is incapable of processing any metadata updates. This causes a deadlock because all the requests that need to do metadata updates wait for metadata_wq to proceed and metadata_wq waits inside wait_and_add_new_range until some existing request releases its range lock (which doesn't happen because the range lock is released after metadata update). In order to fix the deadlock, we create a new workqueue offload_wq and offload requests to it - so that processing of offload_wq is independent from processing of metadata_wq.
