2010-10-18bnx2x: Optimized the branching in the bnx2x_rx_int()Vladislav Zolotarov
Optimized the branching in the bnx2x_rx_int() based on the fact that FP CQE will always have at least one of START or STOP flags set, so if not both bits are set and START bit is not set, then it's a STOP bit that is set.

2010-10-18can: mcp251x: Don't use pdata->model for chip selection anymoreMarc Kleine-Budde
Since commit e446630c960946b5c1762e4eadb618becef599e7, i.e. v2.6.35-rc1, the mcp251x chip model can be selected via the modalias member in the struct spi_board_info. The driver stores the actual model in the struct mcp251x_platform_data. From the driver point of view the platform_data should be read only. Since all in-tree users of the mcp251x have already been converted to the modalias method, this patch moves the "model" member from the struct mcp251x_platform_data to the driver's private data structure.

2010-10-18ns83820: spin_lock_irq() => spin_lock()Dan Carpenter
This is essentially cosmetic. At this point the IRQs are already disabled because we called spin_lock_irq(&dev->rx_info.lock). The real bug here was fixed back in 2006 in 3a10ccebe: "[PATCH] lock validator: fix ns83820.c irq-flags bug". Prior to that patch, it was a "spin_lock_irq is not nestable" type bug. The 2006 patch changes the unlock to not re-enable IRQs, which eliminates the potential deadlock. But this bit was missed. We should change the lock function as well so it balances nicely.

2010-10-18tipc: Simplify bearer shutdown logicAllan Stephens
Optimize processing in TIPC's bearer shutdown code, including: 1. Remove an unnecessary check to see if TIPC bearer's can exist. 2. Don't release spinlocks before calling a media-specific disabling routine, since the routine can't sleep. 3. Make bearer_disable() operate directly on a struct bearer, instead of needlessly taking a name and then mapping that to the struct.
