2009-11-15tg3: Add rx prod ring consolidationMatt Carlson
This patch adds code to funnel each MSI-X vector's rx packet buffers into a single set of producer rings which will then be submitted to the hardware.

2009-11-15tg3: Create aliases for rx producer mailbox regsMatt Carlson
The rx producer mailbox registers are used in several spots in the code. The addition of TG3_64BIT_REG_LOW makes register references uncomfortably long. This patch creates an alias for the standard and jumbo ring producer index registers to make the code cleaner.

2009-11-15tg3: Consider rx_std_prod_idx a hw mailboxMatt Carlson
This patch changes how the code uses the rx_std_prod_idx member. In the following patch, the code will be changed so that it will act just like a hardware mailbox. This patch prepares the code so that memory barriers can be more easily inserted.

2009-11-15tg3: rename rx_[std|jmb]_ptrMatt Carlson

2009-11-15tg3: tg3_alloc_rx_skb(tnapi => tp)Matt Carlson

2009-11-15tg3: Add prodring parameter to tg3_alloc_rx_skb()Matt Carlson
This patch changes the tg3_alloc_rx_skb() implementation to accept the destination producer ring set pointer as a parameter rather than assuming the source and destination producer rings are the same.

2009-11-15tg3: Make tg3_alloc_rx_skb() a dst-only operationMatt Carlson
This patch removes the source index parameter of tg3_alloc_rx_skb(). A later patch will make it possible for the source and destination producer rings to be different. This patch opts to make tg3_alloc_rx_skb() a destination-only implementation and move the code sensitive to the difference elsewhere.

2009-11-15tg3: Move napi_add calls below tg3_get_invariantsMatt Carlson
tg3_get_invariants(), among other things, discovers whether or not the device is MSI-X capable and how many interrupts it supports. This discovery needs to happen before registering NAPI instances with netdev. This patch moves the code block that calls napi_add later in tg3_init_one() so that tg3_get_invariants() has a chance to run first.

2009-11-15tg3: Refine TSO and MSI discoveryMatt Carlson

2009-11-15net: Optimize hard_start_xmit() return checkingJarek Poplawski
Recent changes in the TX error propagation require additional checking and masking of values returned from hard_start_xmit(), mainly to separate cases where skb was consumed. This aim can be simplified by changing the order of NETDEV_TX and NET_XMIT codes, because the latter are treated similarly to negative (ERRNO) values. After this change much simpler dev_xmit_complete() is also used in sch_direct_xmit(), so it is moved to netdevice.h. Additionally NET_RX definitions in netdevice.h are moved up from between TX codes to avoid confusion while reading the TX comment.

2009-11-16Bluetooth: Fix regression with L2CAP configuration in Basic ModeGustavo F. Padovan
Basic Mode is the default mode of operation of a L2CAP entity. In this case the RFC (Retransmission and Flow Control) configuration option should not be used at all. Normally remote L2CAP implementation should just ignore this option, but it can cause various side effects with other Bluetooth stacks that are not capable of handling unknown options.

2009-11-16Bluetooth: Set general bonding security for ACL by defaultAndrei Emeltchenko
This patch fixes double pairing issues with Secure Simple Paring support. It was observed that when pairing with SSP enabled, that the confirmation will be asked twice. http://www.spinics.net/lists/linux-bluetooth/msg02473.html This also causes bug when initiating SSP connection from Windows Vista. The reason is because bluetoothd does not store link keys since HCIGETAUTHINFO returns 0. Setting default to general bonding fixes these issues.

2009-11-15sched, kvm: Fix race condition involving sched_in_preempt_notifersTejun Heo
In finish_task_switch(), fire_sched_in_preempt_notifiers() is called after finish_lock_switch(). However, depending on architecture, preemption can be enabled after finish_lock_switch() which breaks the semantics of preempt notifiers. So move it before finish_arch_switch(). This also makes the in- notifiers symmetric to out- notifiers in terms of locking - now both are called under rq lock.
