The PHY Lib now uses mutexes instead of spin_locks. ucc_geth and gianfar both grab the locks in their mdio_reset functions, so they need to use mutex_(un)lock instead. This was not caught until someone tested it on an SMP system. Signed-off-by:

The driver needs to ack only the phy status bits that it is currently handling and preserve the other bits for the other handlers. For example, when reading/writing from the phy, it should not clear the link change interrupt bit. This will cause a missing link change interrupt. Signed-off-by:

Changes in other networking paths uncovered a bug in the xircom_cb driver which made the kernel spew lots of the following error messages: BUG eth1 code -5 qlen 0 It turned out that the driver returned -EIO when there was no descriptor available for sending packets. It should return NETDEV_TX_BUSY instead. This was discussed on the netdev list before, see http://thread.gmane.org/gmane.linux.network/84603 . Signed-off-by:

Add a parameter to add_partial instead of having separate functions. The parameter allows a more detailed control of where the slab pages is placed in the partial queues. If we put slabs back to the front then they are likely immediately used for allocations. If they are put at the end then we can maximize the time that the partial slabs spent without being subject to allocations. When deactivating slab we can put the slabs that had remote objects freed (we can see that because objects were put on the freelist that requires locks) to them at the end of the list so that the cachelines of remote processors can cool down. Slabs that had objects from the local cpu freed to them (objects exist in the lockless freelist) are put in the front of the list to be reused ASAP in order to exploit the cache hot state of the local cpu. Patch seems to slightly improve tbench speed (1-2%). Signed-off-by:

This patch modifies the get_irqnr_preamble macro to work with multiple platforms at run-time by reading the address of the GIC controller from the gic_cpu_base_addr variable. This variable is defined in core.c and intialised in realview_eb.c (gic_init_irq). Signed-off-by:

This patch moves the IRQ and DMA definitions from core.h into realview_eb.c since they are platform-specific. It adds a realview_eb11mp_fixup function to adjust the IRQ numbers if the ARM11MPCore tile is fitted. The realview_smc91x_device is also moved from core.c into realview_eb.c. Signed-off-by:

This patch moves the platform specific definitions from platform.h into the board-eb.h file. It drops the INT_* definitions as they are no longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_* macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between standard EB and EB + the ARM11MPCore tile. The platform.h file contains common definitions to the RealView platforms and it is only directly included in board-*.h files. Signed-off-by:

This patch adds dummy local timers for each CPU so that the board clock device is used to broadcast events to the other CPUs. The patch also adds the declaration for the dummy_timer_setup function (the equivalent of local_timer_setup when CONFIG_LOCAL_TIMERS is not set). Due to the way clockevents work, the dummy timer on the first CPU has to be registered before the board timer. Signed-off-by:
