Merge tag 'v3.7-rc7' into next/cleanup
Merging in mainline back to next/cleanup since it has collected a few
conflicts between fixes going upstream and some of the cleanup patches.
Git doesn't auto-resolve some of them, and they're mostly noise so let's
take care of it locally.
Conflicts are in:
arch/arm/mach-omap2/omap_hwmod_44xx_data.c
arch/arm/plat-omap/i2c.c
drivers/video/omap2/dss/dss.c
