[PATCH] arm:extend __init_end to a page align address

From: Wang, Yalin
Date: Sun Sep 14 2014 - 22:30:01 EST


this patch change the __init_end address to a
page align address, so that free_initmem() can
free the whole .init section, because if the end
address is not page aligned, it will round down to
a page align address, then the tail unligned page
will not be freed.
