powerpc32: optimise csum_partial() loop On the 8xx, load latency is 2 cycles and taking branches also takes 2 cycles. So let's unroll the loop. This patch improves csum_partial() speed by around 10% on both: * 8xx (single issue processor with parallel execution) * 83xx (superscalar 6xx processor with dual instruction fetch and parallel execution) Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <oss@buserror.net>
