MIPS: Ensure cache ops complete in mips_cache_reset Ensure that cache operations complete before returning from mips_cache_reset by placing a completion barrier (sync instruction) before the return. Without this there is no guarantee that the cache ops will complete before any subsequent memory accesses, since they are indexed cache ops & thus not implicitly ordered with memory accesses.
