Subject: Re: linux-next: Tree for Jul 17

I noticed there are a bunch of new (appeared in the last day or two)
fails spread around, so I did a triage/bisect of them so we have a
better idea of what is going on as we start the week.

Unfortunately I was unable to reproduce the sparc fail, so I don't know
what is going on there....

Biggest culprits are some clk.h reorg fallout, more mlock syscall
fallout, and a sound driver breaking on arch w/o any gpio.

Paul.
