Hi,

I noticed that some of the source files does not include the copyright
information. Most of the files have included it, but few files have
not included it. I felt it should be included. The attached patch
contains the fix for including the copyright information in the source
files. Let me know your thoughts on the same.

Regards,
Vignesh

Subject: [PATCH] Make the copyright information consistent in the source
files.

The basic rule we follow here is to include the copyright information in the
beginning of the source files. We generally follow these rules, but the code
has deviated in many places. This commit makes it consistent.
