x86: lds - Use PAGE_SIZE instead of numeric constant
It's much better to use PAGE_SIZE then magic 4096 (though it's almost synonym in most cases on x86 but not for *all* cases ;) Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
