.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.

From: Nelson Elhage <[email protected]>
Note that this patch moves .data.init_task inside _edata. In
addition, the alignment of .init.ramfs changes: It is now PAGE_ALIGNED
and __initramfs_end is arbitrarily aligned; Previously it was
only aligned to a 0x100-byte boundary, and always ended on an even
byte.
This change results in fewer output sections and in some data being
reordered, but should have no functional effect.
