[PATCH] uml: fix build warnings in __get_user

Fix a gcc warning about losing qualifiers to the first argument of
copy_from_user.  The typeof change for correctness, and fixes a lot of the
warnings, but there are some cases where x has some extra qualifiers, like
volatile, which copy_from_user can't know about.  For these, the void * cast
seems to be necessary.

Also cleaned up some of the whitespace and got rid of the emacs comment at the
bottom.
