Subject: i386: force data segment to be 4K aligned
From: Vivek Goyal <vgoyal@xxxxxxxxxx>
Currently there is no specific alignment restriction in linker script and in
some cases it can be placed non 4K aligned addresses. This fails kexec which
checks that segment to be loaded is page aligned.
I guess, it does not harm data segment to be 4K aligned.
