sh: Default to 4-byte alignment for SLUB objects.
Slub currently defaults to 8-byte alignment for the kmalloc and slab minalign values, where 4 will suffice. In the slab case BYTES_PER_WORD == 4 already, so defining the minalign values outright doesn't cause any regressions there either. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
