Linux 4.0 rc6

Things are calming down nicelly, and there are fixes all over. TheNUMA balancing performance regression is fixed, and things are lookingup again in general. There were a number of i915 issues and a KVMdouble-fault thing that meant that for a while there I was pretty surethat this would be a release that will go to rc8, but that may beunnecessary.Apart from the aforementioned issues, the bulk of this is mostly smallmisc driver fixes and architecture updates. The shortlog gives more ofa flavor of what's been going on.But please do give this a good testing, and holler if there's someregression we've missed.                          Linus
