In a prior patch, I introduced a sk_hash field (__sk_common.skc_hash) to let tcp lookups use one cache line per unmatched entry instead of two. We can also use sk_hash to speedup UDP part as well. We store in sk_hash the hnum value, and use sk->sk_hash (same cache line than 'next' pointer), instead of inet->num (different cache line) Note : We still have a false sharing problem for SMP machines, because sock_hold(sock) dirties the cache line containing the 'next' pointer. Not counting the udp_hash_lock rwlock. (did someone mentioned RCU ? :) ) Signed-off-by:

The ATA_ENABLE_PATA define was never meant to be permanent, and in recent kernels, it's already been unconditionally enabled. Remove. Signed-off-by:Jeff Garzik <jeff@garzik.org>

If we are doing a PIO setup for a CFA card and it blows up with a device error then assume it is an older CFA card which doesn't support this rather than failing the device out of existance. Stands seperate to the quieting patch but that is obviously useful with this change. Signed-off-by:
