CONFIG_CGROUPS is disabled in highbank

Bug Description

SRU justification:

Impact: CONFIG_CGROUPS not enabled for highbank kernel

Fix: Apply patch to enable it

TestCase: See https://bugs.launchpad.net/eilt/+bug/1014692/comments/4

$ git cat-file blob quantal/master:debian.master/config/armhf/config.flavour.highbank | grep CGR
# CONFIG_CGROUPS is not set

$ git cat-file blob precise/master:debian.master/config/armhf/config.flavour.highbank | grep CGR
# CONFIG_CGROUPS is not set

Patch for ubuntu-precise

Patch for ubuntu-quantal

Looks what we need is there with patched kernel

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

There is no cgroup supported with old kernel

ubuntu@c02:~$ cat /proc/version
Linux version 3.2.0-26-highbank (buildd@nihal) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #41-Ubuntu SMP PREEMPT Thu Jun 14 20:55:11 UTC 2012
ubuntu@c02:~$ cat /proc/filesystems | grep cgroup

and it looks good with new kernel
