2010-05-17bnx2x: avoid TX timeout when stopping deviceStanislaw Gruszka
When stop device call netif_carrier_off() just after disabling TX queue to avoid possibility of netdev watchdog warning and ->ndo_tx_timeout() invocation.

2010-05-17bnx2: Use netif_carrier_off() to prevent timeout.Michael Chan
Based on original patch from Stanislaw Gruszka <sgruszka@redhat.com>. Using netif_carrier_off() is better than updating all the ->trans_start on all the tx queues. netif_carrier_off() needs to be called after bnx2_disable_int_sync() to guarantee no race conditions with the serdes timers that can modify the carrier state. If the chip or phy is reset, carrier will turn back on when we get the link interrupt. If there is no reset, we need to turn carrier back on in bnx2_netif_start(). Again, the phy_lock prevents race conditions with the serdes timers. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: David S.

2010-05-17netdev: bfin_mac: handle timeouts with the MDIO registers gracefullyMike Frysinger
Have the low level MDIO functions pass back up timeout information so we don't waste time polling them multiple times when there is a problem, and so we don't let higher layers think the device is available when it isn't.

2010-05-17netdev: bfin_mac: use promiscuous flag for promiscuous modeSonic Zhang
Rather than using the Receive All Frames (RAF) bit to enable promiscuous mode, use the Promiscuous (PR) bit.

2010-05-17netdev: bfin_mac: deduce Ethernet FCS from hardware IP payload checksumSonic Zhang
IP checksum is based on 16-bit one's complement algorithm, so to deduce a value from checksum is equal to add its complement. Unfortunately, the Blackfin on-chip MAC checksum logic only works when the IP packet has a header length of 20 bytes. This is true for most IPv4 packets, but not for IPv6 packets or IPv4 packets which use header options. So only use the hardware checksum when appropriate.

2010-05-17netdev: bfin_mac: invalid data cache only once for each new rx skb bufferSonic Zhang
The skb buffer isn't actually used until we finish transferring and pass it up to higher layers, so only invalidate the range once before we start receiving actual data. This also avoids the problem with data invalidating on Blackfin systems -- there is no invalidate-only, just invalidate+flush. So when running in writeback mode, there is the small (but not uncommon) possibility of the flush overwriting valid DMA-ed data from the cache.

2010-05-17net: No dst refcounting in ip_queue_xmit()Eric Dumazet
TCP outgoing packets can avoid two atomic ops, and dirtying of previously higly contended cache line using new refdst infrastructure. Note 1: loopback device excluded because of !IFF_XMIT_DST_RELEASE Note 2: UDP packets dsts are built before ip_queue_xmit().

2010-05-17net: Use ip_route_input_noref() in input pathEric Dumazet

2010-05-17net: implements ip_route_input_noref()Eric Dumazet
ip_route_input() is the version returning a refcounted dst, while ip_route_input_noref() returns a non refcounted one. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-05-17net: add a noref bit on skb dstEric Dumazet
Use low order bit of skb->_skb_dst to tell dst is not refcounted. Change _skb_dst to _skb_refdst to make sure all uses are catched. skb_dst() returns the dst, regardless of noref bit set or not, but with a lockdep check to make sure a noref dst is not given if current user is not rcu protected. New skb_dst_set_noref() helper to set an notrefcounted dst on a skb. (with lockdep check) skb_dst_drop() drops a reference only if skb dst was refcounted. skb_dst_force() helper is used to force a refcount on dst, when skb is queued and not anymore RCU protected. Use skb_dst_force() in __sk_add_backlog(), __dev_xmit_skb() if !IFF_XMIT_DST_RELEASE or skb enqueued on qdisc queue, in sock_queue_rcv_skb(), in __nf_queue(). Use skb_dst_force() in dev_requeue_skb(). Note: dst_use_noref() still dirties dst, we might transform it later to do one dirtying per jiffies.

2010-05-17rps: avoid one atomic in enqueue_to_backlogEric Dumazet
If CONFIG_SMP=y, then we own a queue spinlock, we can avoid the atomic test_and_set_bit() from napi_schedule_prep().

2010-05-17x86, hweight: Use a 32-bit popcnt for __arch_hweight32()H. Peter Anvin
Use a 32-bit popcnt instruction for __arch_hweight32(), even on x86-64. Even though the input register will *usually* be zero-extended due to the standard operation of the hardware, it isn't necessarily so if the input value was the result of truncating a 64-bit operation. Note: the POPCNT32 variant used on x86-64 has a technically unnecessary REX prefix to make it five bytes long, the same as a CALL instruction, therefore avoiding an unnecessary NOP.

2010-05-17cifs: don't update uniqueid in cifs_fattr_to_inodeJeff Layton
We use this value to find an inode within the hash bucket, so we can't change this without re-hashing the inode. For now, treat this value as immutable. Eventually, we should probably use an inode number change on a path based operation to indicate that the lookup cache is invalid, but that's a bit more code to deal with.
