Hint, when you have to list all of the different things you are doing in
a single commit, that is a good clue that you should be splitting up the
commit into "one per thing".

This commit has way too many things happening all at once, and is very
difficult to review because of that. What would you do if you were
confronted with a single patch like this and you had to review it?

Make it trivial to review, please break this up into smaller pieces.

thanks,

greg k-h
