cpuset disabled

[Rob Woolley]

Hi,

I noticed that cpuset was disabled when using my Raspberry Pi.  Others
have also run into this in the forums:
https://www.raspberrypi.org/forums/viewtopic.php?t=178981&p=1139830

I reverted this commit and it restored cpuset:
https://github.com/raspberrypi/linux/commit/7dbc189967bef8e7f431c982557d0e73eb13f161

It seems that the commit was actually trying to disable the memory
resource controller.  I can confirm that "memory" remains enabled when
the patch is present.  Also using cgroup_enable=cpuset does re-enable
cpuset.

I thought I should report it in case it helps others.  Would you be
open to reverting the commit?

Regards,
Rob
