Make sure that the 'static' keywork is at the beginning of declaration for drivers/net/usb/kalmia.c This gets rid of warnings like warning: ‘static’ is not at beginning of declaration when building with -Wold-style-declaration (and/or -Wextra which also enables it).

2011-07-11neigh: Store hash shift instead of mask.David S. Miller
And mask the hash function result by simply shifting down the "->hash_shift" most significant bits. Currently which bits we use is arbitrary since jhash produces entropy evenly across the whole hash function result. But soon we'll be using universal hashing functions, and in those cases more entropy exists in the higher bits than the lower bits, because they use multiplies. Signed-off-by: David S.

2011-07-08sky2: support for new Optima chipsets (EXPERIMENTAL)stephen hemminger
This is a backport from the vendor driver of support for the newer Optima (Prime and 2) chipsets. It also includes some setup changes for the current Optima chip as well. The code and comments intentionally mirror the vendor sk98lin driver to allow for easier maintenance. Although this adds support for new chip id's, these chip id's are not used by any of the current PCI device id's listed in the driver. The patch is just to get initial infrastructure in place to handle them when they come. I don't have access to any of this hardware to actually test it yet.

2011-07-07rt2x00: Implement tx_frames_pending mac80211 callback function.Gertjan van Wingerde
Implementing this callback function will cause mac80211 refrain from going to powersave state when there are still untransmitted TX frames in the queues. This would exactly mimic the behaviour of the legacy vendor driver which also doesn't go in powersave mode if there are still TX frames that are not transmitted. This should make powersaving and rt2x00 a better couple.

2011-07-07rt2x00: Serialize TX operations on a queue.Gertjan van Wingerde
The rt2x00 driver gets frequent occurrences of the following error message when operating under load: phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 2. This is caused by simultaneous attempts from mac80211 to send a frame via rt2x00, which are not properly serialized inside rt2x00queue_write_tx_frame, causing the second frame to fail sending with the above mentioned error message. Fix this by introducing a per-queue spinlock to serialize the TX operations on that queue.

2011-07-07batman-adv: keep local table consistency for further TT_RESPONSEAntonio Quartulli

2011-07-07skbuff: skb supports zero-copy buffersShirley Ma
This patch adds userspace buffers support in skb shared info.

If there is any userspace apps to reference these userspace buffers, then these userspaces buffers will be copied into kernel. This way we can prevent userspace apps from holding these userspace buffers too long. Use destructor_arg to point to the userspace buffer info; a new tx flags SKBTX_DEV_ZEROCOPY is added for zero-copy buffer check. Signed-off-by: Shirley Ma <xma@...ibm.com> Signed-off-by: David S.
