While reading about initcalls around the web and kernel source code I found
that the information of what happens to __init functions not explicitly set to
any initcall list pretty useful. With this patch such information is added.

This patch handle different typos present in the initcall section of the book.
It also reword some paragraphs in order to get it clearer to the reader.
Some example codes were also added in order to help the reader to understand
smaller concepts, like the way initcalls callbacks are named in the object
file.
