When fixing selftests by adding support for wide stores, Yonghong reported that he had seen some examples where clang generates single u64 loads for two adjacent u32s as well: http://lore.kernel.org/netdev/a66c937f-94c0-eaf8-5b37-8587d66c0c62@xxxxxx Let's support aligned u64 reads for some bpf_sock_addr fields as well. (This can probably wait for bpf-next, I'll defer to Younhong and the maintainers.)
