In 32 bit architecture, "size" could be zero, ref. line 1909:
uint64_t size = pkt->pkt_len + sizeof(struct virtio_net_hdr_mrg_rxbuf);
The values on both sides of the addition are 32 bit unsigned, so the addition will be performed as 32 bit unsigned, and the result could in theory be 0. Casting one of them to 64 bit, e.g. (uint64_t)sizeof(struct virtio_net_hdr_mrg_rxbuf), might fix the warning if the compiler is clever enough to know that adding a non-zero 64 bit value to any 32 bit value cannot give zero as the result.
Side note, off track: Why is "size" uint64_t, wouldn't uint32_t suffice?

That is indeed the relevant question here!
Perhaps the compiler somehow ignores the "const" part of the parameter given to the "asm" (in rte_prefetch0()) for 64 bit arch, but not for 32 bit arch?
