The manual says that it is required and we actually have crash reports
where loads see stale data due to not having membars here.
In one case the networking does:
memset(skb, 0, offsetof(struct sk_buff, truesize));
and then some code later checks skb->nohdr for zero, but it's still
the value that was there before the memset().
Note that arch/sparc64/lib/xor.S already got this right.

We need to restore the %asi register properly.
For the kernel this means get_fs(), for user this
means ASI_PNF.
Also, NGcopy_to_user.S was including U3memcpy.S instead
of NGmemcpy.S, oops :-)
