Linux 3.16 rc4

Things have calmed down nicely, and everything seems pretty normal.
Maybe some of the calm has been due to people starting to take off for
summer and (in the US) the 4th of July week, but whatever the reason,
both the diffstat and the logs look nice and fairly small.

Most of the changes are in drivers (gpu, usb, scsi, sound),
filesystems (btrfs, ext4) and arch updates (mostly arm). With a
smattering of misc random stuff. But it's all pretty small.

Go out and test it,
