Avoid SMP calls for flushing small icache ranges. On non-CM platforms, and CM platforms too after we make r4k_on_each_cpu() take the cache op type into account, it will be called on multiple CPUs due to the possibility that local_r4k_flush_icache_range_ipi() could do non-globalized indexed cache ops. This rougly copies the range size check out into r4k_flush_icache_range(), which can disallow indexed cache ops and allow r4k_on_each_cpu() to skip the SMP call. Signed-off-by:
