Linux 4.18 rc1

ou may think it's still Saturday for me, and that  I should give you
one more day of merge window to send in some last-minute pull
requests, but I know better. I'm in Japan, and it's Sunday here. Plus
I hope to spend much of this Sunday on a boat (assuming the swells
allow it), so I'm closing the merge window early morning rather than
in the afternoon.

So here we are - no more merge window, so please don't even try to
send me updates any more. Just fixes, please.
