Why can't we just make the comments into code by removing the /*
characters?  Remove the cast by declaring the data as __user data to
begin with instead of declaring it incorrectly and then casting to the
correct type later.

Also it's not allowed to send two patches with the exact same subject.
Also the subject was sucky and too vague anyway.  :)
