When I boot with the 'quiet' parameter, I see on the screen:

[    0.000000] Initializing cgroup subsys cpuset
[    0.000000] Initializing cgroup subsys cpu
[   39.036026] Initializing cgroup subsys cpuacct
[   39.036080] Initializing cgroup subsys debug
[   39.036118] Initializing cgroup subsys ns

This patch lowers the priority of those messages, adds a "cgroup: " prefix
to another couple of printks and kills the useless reference to the source
file.
