Linux 3.19 rc5

Another week, another -rc.Fairly normal release, although I'd wish that by rc5 we'd have calmeddown even further.  But no, with some of the driver tree merges inparticular, this is actually larger than rc4 was.That said, it's not like there is anything particularly scary in here.The arm64 vm bug that I mentioned as pending in the rc4 notes gotfixed within a day of that previous rc release, and the rest lookspretty standard. Mostly drivers (networking, usb, scsi target, blocklayer, mmc,  tty etc), but also arch updates (arm, x86, s390 and sometiny powerpc fixes), some filesystem updates (fuse and nfs), tracingfixes, and some perf tooling fixes.Shortlog with the details appended.Go forth and test.
