Linux 3.12 rc4

Hmm. rc4 has more new commits than rc3, which doesn't make me feel allwarm and fuzzy, but nothing major really stands out. More filesystemupfates than normal at this stage, perhaps, but I suspect that is justhappenstance. We have cifs, xfs, btrfs, fuse and nilfs2 fixes here.There's the usual driver updates too (mainly net and target this timearound), along with some generic networking changes too. And some archupdates (arm, power, s+core, avr32).But nothing scary, so go out and test.                 Linus
