[PATCH] ARM: multi_v7_defconfig: Enable cgroups

[Soren Brinkmann]

This allows booting the kernel with systemd-based root file systems.

Hi,

I don't know whether I'm the only one, but I use a initramfs with
systemd as init, which requires cgroup support in the kernel to fully
boot.

	Thanks,
	S?ren

You probably are at this time, but I expect it to get more common
in the future, I don't think enabling this is controversial at all.

Applied to next/defconfig, thanks!

Others are using it but with SoC specific defconfig and not multi_v7.

Newer version of systemd needs more config symbols to be enabled
besides cgroups, the full list is at
http://cgit.freedesktop.org/systemd/systemd/tree/README.

Tony recently added the recommended support to OMAP2+ defconfig so
something along these lines should be added to multi_v7 as a
follow-up:

673ce00c ("ARM: omap2plus_defconfig: Add support for distros with systemd")

Best regards,
Javier
