Loongson 2 currently does not have dcache alias actually, because it is using 16k page, and the dcache is 4 way set associative 64k VIPT cache. It will have dcache alias if the page size is smaller than 16k. And because Loongson 2 is not an SMP cpu, cpu_icache_snoops_remote_store does not matter here.
