tpci200_interrupt() Minor cleanup. No functional changes. Signed-off-by: Jens Taprogge <jens.taprogge@taprogge.org> Signed-off-by: Samuel Iglesias Gonsalvez <siglesias@igalia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-09-12Staging: ipack/bridges/tpci200: Clean up interrupt handling.Jens Taprogge
Previously the return value from tpci200_interrupt was not quite correct if a slot had caused an interrupt but no handler was instellalled: IRQ_NONE was returned. However in this case we react to the interrupt by disabling the IPack device interrupt. Basically there are two cases the code now distinguishes: - The tpci200 has raised an interrupt. We handle it and return IRQ_HANDLED. - Our device did not raise an interrupt. We return IRQ_NONE.

2012-09-12Staging: ipack/bridges/tpci200: Protect device registers with spinlock.Jens Taprogge
Some of the device registers are accessed from both interrupt and non-interrupt context. To ensure proper read-modify-write modification of these registers we can not use the "global" tpci200 mutex. Instead a spin-lock is used.

2012-09-12Staging: ipack/bridges/tpci200: RCU protect slot_irq pointers.Jens Taprogge
In tpci200_request_irq as well as tpci200_free_irq we set and unset the pointer to struct slot_irq. This pointer is accessed in tpci200_interrupt. To ensure that the pointer is not freed after it has been fetched in tpci200_interrupt() it is now protected through RCU.

2012-09-12IPoIB: Fix AB-BA deadlock when deleting neighboursShlomo Pongratz
Lockdep points out a circular locking dependency betwwen the ipoib device priv spinlock (priv->lock) and the neighbour table rwlock (ntbl->rwlock). In the normal path, ie neigbour garbage collection task, the neigh table rwlock is taken first and then if the neighbour needs to be deleted, priv->lock is taken. However in some error paths, such as in ipoib_cm_handle_tx_wc(), priv->lock is taken first and then ipoib_neigh_free routine is called which in turn takes the neighbour table ntbl->rwlock. The solution is to get rid the neigh table rwlock completely and use only priv->lock.

2012-09-12IPoIB: Fix memory leak in the neigh table deletion flowShlomo Pongratz
If the neighbours hash table is empty when unloading the module, then ipoib_flush_neighs(), the cleanup routine, isn't called and the memory used for the hash table itself leaked. To fix this, ipoib_flush_neighs() is allways called, and another completion object is added to signal when the table is freed. Once invoked, ipoib_flush_neighs() flushes all the neighbours (if there are any), calls the the hash table RCU free routine, which now signals completion of the deletion process, and waits for the last neighbour to be freed.

2012-09-12i2c: pnx: Fix read transactions of >= 2 bytesRoland Stigge
On transactions with n>=2 bytes, the controller actually wrongly clocks in n+1 bytes. This is caused by the (wrong) assumption that RFE in the Status Register is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to the implementation of synchronized byte ordering, e.g.: Dummy-TX - RX - Dummy-TX - RX - ... But since RFE actually stays high after some Dummy-TX, it rather looks like: Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX) The last RX byte is clocked in by the bus controller, but ignored by the kernel when filling the userspace buffer. This patch fixes the issue by asking for RX via Dummy-TX asynchronously. Introducing a separate counter for TX bytes.

2012-09-12xen/m2p: do not reuse kmap_op->dev_bus_addrStefano Stabellini
If the caller passes a valid kmap_op to m2p_add_override, we use kmap_op->dev_bus_addr to store the original mfn, but dev_bus_addr is part of the interface with Xen and if we are batching the hypercalls it might not have been written by the hypervisor yet. That means that later on Xen will write to it and we'll think that the original mfn is actually what Xen has written to it. Rather than "stealing" struct members from kmap_op, keep using page->index to store the original mfn and add another parameter to m2p_remove_override to get the corresponding kmap_op instead. It is now responsibility of the caller to keep track of which kmap_op corresponds to a particular page in the m2p_override (gntdev, the only user of this interface that passes a valid kmap_op, is already doing that).

2012-09-12trace: Don't declare trace_*_rcuidle functions in modulesJosh Triplett
Tracepoints declare a static inline trace_*_rcuidle variant of the trace function, to support safely generating trace events from the idle loop. Module code never actually uses that variant of trace functions, because modules don't run code that needs tracing with RCU idled. However, the declaration of those otherwise unused functions causes the module to reference rcu_idle_exit and rcu_idle_enter, which RCU does not export to modules. To avoid this, don't generate trace_*_rcuidle functions for tracepoints declared in module code.

However, the data passed from and to the SMBus word API functions is in host byte order, not in chip byte order. Conversion should therefore use swab16 instead of be16 to change the byte order.

2012-09-12x86: Remove base argument from x86_init.paging.pagetable_setup_startAttilio Rao
We either use swapper_pg_dir or the argument is unused. Preparatory patch to simplify platform pagetable setup further.

2012-09-12rpmsg: fix dma_free_coherent dev parameterFernando Guzman Lugo
dma_alloc/free_coherent APIs requires the platform specific remoteproc device as the device parameter. We are passing vdev->dev.parent to the dma_free_coherent function which is the generic rproc device and it is wrong, it has to be vdev->dev.parent->parent instead, same as when we call dma_alloc_coherent function.
