Subjectget_user()

Is getting rid of all the get_fs_...() macros really an improvement?

I don't know whether the get_user() macro really hides any ugliness, because

1. you have to be aware of the fact that it's a macro because it alters one
of its parameters and
2. you _should_ probably remain aware that performance may be
type-dependent.

Or are there other aspects that are more important?
