* [SPARC64]: store-init needs trailing membar.David S. Miller2007-03-19
| | | | | | | | | | | | | | | | 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. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix some Niagara memcpy() bugs.David S. Miller2006-03-20
| | | | | | | | | | | 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 :-) Signed-off-by: David S. Miller <davem@davemloft.net>
