Linux 5.6 rc4

Hmm. Fairly reasonably sized rc4, and the diffstat looks nice and flattoo (which basically means "lots of small changes") except for anetfilter ipset fix that ended up being somewhat big and involved dueto locking changes.That single commit shows up in the dirstat too, and accounts for about1/6th of the whole patch.Anyway, everything else looks fairly small. There's a couple ofethernet drivers that got a few bigger changes, but there really is alot of small stuff all over: architectures (x86, arm64, risc-v),drivers (gpu, hid, networking), filesystems (zonefs and ext4), andsome tracing code.The shortlog is appended for the people who want to skim the details.
