Christophe Leroy d10f60ae27 powerpc/32s: fix allow/prevent_user_access() when crossing segment boundaries.
Make sure starting addr is aligned to segment boundary so that when
incrementing the segment, the starting address of the new segment is
below the end address. Otherwise the last segment might get  missed.
