Or your original patch was

+#ifdef CONFIG_ARC_HAS_LL64
+#define ARCH_SLAB_MINALIGN 8
+#endif

I don't think this issue is related to LL64 at all. A long long on ARC could be 4
byte aligned (as mandated by the ABI). It could use LDD or 2 separate LDs. This
has no bearing on the fact that LLOCKD have to use a 64-bit aligned addresses. So
I think we should just do this unconditionally. Agree ?
