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 ?
