The problem seems to be that the new struct sock_common ends with a
pointer and an atomic_t (which is an int on parisc), so the compiler
adds an extra four bytes of padding where none previously existed in
struct tcp_tw_bucket, so the __u64 ptr tricks with tw_daddr fail.
A fix that seems to work for me on parisc64 is to move the atomic_t out
of the end of struct sock_common and back into the two other structures
(so struct sock_common now ends on 0 mod 8).
