Linux 4.13 rc2

Things are chugging along, and we actually had a reasonably active rc2.Normally rc2 is really small because people are taking a breaher andhaven't started finding bugs yet, but this time around we have abigger-than-average rc2. We'll just have to see how that translates tothe rest of the release cycle, but I suspect it's just the normalvariability in this thing (and because I released -rc1 one day early,I guess rc2 was one day longer than usual despite the normal Sundayrelease).Changes all over, although the diffstat is dominated by the newvboxvideo staging driver. I shouldn't have let it through, but Greg,as we all know, is "special". Also, Quod licet Iovi, and all that jazz- Greg gets to occasionally break some rules.If you just ignore that new staging driver, the remainder is stillabout half driver patches (networking, rdma, scsi, usb). The restlooks normal too: architecture updates (x86, sparc, powerpc),filesystem (nfs, overlayfs, misc), networking and core kernel. Andsome new bpf testcode.Time for some more testing, people. You know the drill.                          Linus
