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 Signed-off-by: Olof Johansson <olof@lixom.net>

5.3 swappiness
Similar to /proc/sys/vm/swappiness, but affecting a hierarchy of groups only.
+Please note that unlike the global swappiness, memcg knob set to 0
+really prevents from any swapping even if there is a swap storage
+available. This might lead to memcg OOM killer if there are no file
+pages to reclaim.
Following cgroups' swappiness can't be changed.
- root cgroup (uses /proc/sys/vm/swappiness).
