Kernel prepatch 5.6-rc1

Linus has released 5.6-rc1 and closed themerge window for this development cycle. "This was actually aslightly smaller merge window than usual, but I think that what happened issimply that the holiday season impacted new development. It impacted the5.5 rc series less than I had expected, but seems to instead have caused5.6 to have slightly less development than normal."
