Linux 4.9 rc7

Still on the regular Sunday release schedule, here's rc7.I think we got all the silly problems I was aware of fixed, and on thewhole things are looking pretty good. In fact, if next week ends upbeing very quiet, this _might_ be the last rc, although honestly Istrongly suspect I'll end up doing an rc8. It's been a big release,and rc7 could have been quieter. We'll see.I basically reserve the right to make up my mind next weekend.The changes in rc7 are mainly drivers, architecture and networking. Infact, most of the driver updates are networking drivers, so I guess Icould say "mostly networking and architecture updates, with asmattering of other driver updates" (the main other driver areas beingusb, gpu, hid, i2c, iommu).  And we've got the usual small randomstuff all over (core kernel, a eBPF fix, some filesystem fixes etc).The appended shortlog gives a reasonable view into what's up.                  Linus
