.data.page_aligned should not need a separate output section, so as part of this cleanup I moved into the .data output section in the linker scripts in order to eliminate unnecessary references to the section name. Remove the reference to .data.idt, since nothing is put into the .data.idt section on the s390 architecture. It looks like Cyrill Gorcunov posted a patch to remove the .data.idt code on s390 previously: <http://lkml.indiana.edu/hypermail/linux/kernel/0802.2/2536.html> CCing him and the people who acked that patch in case there's a reason it wasn't applied.
