Subject: [PATCH 1/1] kernel booting messages, first line

For -rc8 ,

Hoping that someone DO cares about the aesthetic of kernel messages at boot :

What it does : first line of booting kernel, as seen in dmesg(1), will be the Linux kernel signature
(version, compiler, compiler hostname).

What it solves : it appers ahead of cgroup messages at booting.

This ugliness, since 3.10.x kernel.

So :

Instead of the unaesthetic lines :

Initializing cgroup subsys cpuset
Initializing cgroup subsys cpu
Initializing cgroup subsys cpuacct
Linux version 4 ...

... We will have :

Linux version 4 ...
Initializing cgroup subsys cpuset
Initializing cgroup subsys cpu
Initializing cgroup subsys cpuacct

As normal .
