The second 3.12 kernel prepatch is out. Linus said: "Things have been fairly quiet, probably because lots of people were traveling for LinuxCon and Linux Plumbers conference last week. So nothing very exciting stands out. It's mainly driver updates/fixes (gpu drivers stand out, but there's networking too, and smaller stuff all over). Apart from drivers there's arch updates (tile/arm/mips) and some filesystem noise (mainly btrfs)."
