Linux 3.18 rc6

Steady progress towards final release, although we still have a bigunknown worry in a regression that Dave Jones reported and that wehaven't solved yet. In the process of chasing that one down, there'sbeen a fair amount of looking at various low-level details, and thatfound some dubious issues, but no smoking gun yet. But that explainssome of the patches in rc6..The good news is that things are generally calming down, and most ofthe changes are smallish regression fixes here, with a smattering ofstable patches. About half drivers (networking, sound, pci,infiniband, etc), with architecture updates (x86, mips, arm), andnetworking code being about half of the rest. And the last quarter is"misc": filesystem fixes, documentation, scheduler..Really not a whole lot of code changed, and if it wasn't for thepending trouble from DaveJ, I'd probably be perfectly happy. Let's seehow that all unfolds, but in the meantime, the more testing this canget, the better.So go out and give it a good shake-down,                     Linus
