    [PATCH] i386: Force data segment to be 4K aligned
    
    o 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.
    
    o I guess, it does not harm data segment to be 4K aligned.
