Linux 4.17 rc6

Things continue to be fairly calm. There's a couple of commits in here thataren't "trivial few-liners", but most of it really is pretty small. And infact, a quarter of the full patch for the week is tooling - and the bulk ofthat is the testing subdirectory.In fact, drivers are in the minority here, because another 30% is archupdates (arm, s390, x86), and we even have more lines of filesystem fixesthan we have driver fixes (admittedly mostly due to a few of themore-than-a-few-liner patches being to filesystems: afs and btrfs).We do have a few driver fixes (all over - hwmon, usb, sound, acpi, gpu),but it's all really small.So nothing special to report. Go read the shortlog, pull the changes,build, and test.  It should all be good and pretty stable by this point.                 Linus
