Linux 4.18 rc8

So as already mentioned a couple of times in some of the relevantthreads, this last week wasn't entirely painless, and 4.18 ended upbeing one of those releases that gets an extra week of rc testingbefore release.The original impetus for this was the continued VM worries - althoughit looks like we finally root-caused all the issues and got it all inshape on Wednesday. Still, that is somewhat late, and merits anotherrc for final testing.That said, if it had been _only_ that silly VM issue that turned outto not be so annoying as it could have been, I might have reconsideredand done a final release anyway, but we had some last-minutenetworking noise too, and there's actually a pending (old) VFS issuetoo. So while I may prefer to keep our regular release cadence, butthis time around we are just going to see that extra week.I realize that this may mess with people who had planned for the mergewindow to start tomorrow - particularly the Europeans where August isoften peak vacation time. Never fear, you can send me your mergewindow pull request next week as planned, and I'll just sit on it forthe extra week. So go off on your planned vacations.Anyway, appended is the shortlog for the changes during the last week- and despite the extra week, it's not really horrible. Over a quarterof the patch is tooling updates, with some testing and tooling updatesfor perf, turbostat and bpf.On the actual kernel side, most of the (small) changes were todrivers, with network drivers leading the way. There's also some corenetworking changes, along with some minor arch updates.And we've got the VM fixes. and misc noise elsewhere. See below forthe shortlog, or delve into the git repo for the nitty-gritty details.                    Linus
