Currently there were two part of DMAC PL330 driver for support old styled s3c-pl330 which has been merged into drivers/dma/pl330.c driver. Actually, there is no reason to separate them now.

2012-03-08KVM: Allow host IRQ sharing for assigned PCI 2.3 devicesJan Kiszka2-0/+8
PCI 2.3 allows to generically disable IRQ sources at device level. This enables us to share legacy IRQs of such devices with other host devices when passing them to a guest. The new IRQ sharing feature introduced here is optional, user space has to request it explicitly. Moreover, user space can inform us about its view of PCI_COMMAND_INTX_DISABLE so that we can avoid unmasking the interrupt and signaling it if the guest masked it via the virtualized PCI config space.

2012-03-08KVM: Ensure all vcpus are consistent with in-kernel irqchip settingsAvi Kivity1-0/+7
If some vcpus are created before KVM_CREATE_IRQCHIP, then irqchip_in_kernel() and vcpu->arch.apic will be inconsistent, leading to potential NULL pointer dereferences. Fix by: - ensuring that no vcpus are installed when KVM_CREATE_IRQCHIP is called - ensuring that a vcpu has an apic if it is installed after KVM_CREATE_IRQCHIP This is somewhat long winded because vcpu->arch.apic is created without kvm->lock held.

2012-03-08spi: create a message queueing infrastructureLinus Walleij1-0/+51
This rips the message queue in the PL022 driver out and pushes it into (optional) common infrastructure. Drivers that want to use the message pumping thread will need to define the new per-messags transfer methods and leave the deprecated transfer() method as NULL. Most of the design is described in the documentation changes that are included in this patch. Since there is a queue that need to be stopped when the system is suspending/resuming, two new calls are implemented for the device drivers to call in their suspend()/resume() functions: spi_master_suspend() and spi_master_resume(). ChangeLog v1->v2: - Remove Kconfig entry and do not make the queue support optional at all, instead be more agressive and have it as part of the compulsory infrastructure. - If the .transfer() method is implemented, delete print a small deprecation notice and do not start the transfer pump. - Fix a bitrotted comment. ChangeLog v2->v3: - Fix up a problematic sequence courtesy of Chris Blair. - Stop rather than destroy the queue on suspend() courtesy of Chris Blair.

git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc into next/rpmsg Fixing and cleaning up several remoteproc and rpmsg issues. In addition, remoteproc's resource table is converted to a collection of type-value members, instead of a rigid array of homogeneous structs. This enables remoteproc to support registration of generic virtio devices, and not only a single VIRTIO_ID_RPMSG virtio device. But perhaps more importantly, the resource table overhaul makes it possible to easily extend it in the future without breaking older images (simply by defining a new member type, while continuing to support older types). * tag 'rpmsg-fixes-and-more-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc: remoteproc: cleanup resource table parsing paths remoteproc: remove the hardcoded vring alignment remoteproc/omap: remove the mbox_callback limitation remoteproc: remove the single rpmsg vdev limitation remoteproc: safer boot/shutdown order remoteproc: remoteproc_rpmsg -> remoteproc_virtio remoteproc: resource table overhaul rpmsg: fix build warning when dma_addr_t is 64-bit rpmsg: fix published buffer length in rpmsg_recv_done rpmsg: validate incoming message length before propagating rpmsg: fix name service endpoint leak remoteproc/omap: two Kconfig fixes remoteproc: make sure we're parsing a 32bit firmware
2012-03-07netfilter: xt_CT: allow to attach timeout policy + glue codePablo Neira Ayuso1-0/+12
This patch allows you to attach the timeout policy via the CT target, it adds a new revision of the target to ensure backward compatibility. Moreover, it also contains the glue code to stick the timeout object defined via nfnetlink_cttimeout to the given flow. Example usage (it requires installing the nfct tool and libnetfilter_cttimeout): 1) create the timeout policy: nfct timeout add tcp-policy0 inet tcp \ established 1000 close 10 time_wait 10 last_ack 10 2) attach the timeout policy to the packet: iptables -I PREROUTING -t raw -p tcp -j CT --timeout tcp-policy0 You have to install the following user-space software: a) libnetfilter_cttimeout: git://git.netfilter.org/libnetfilter_cttimeout b) nfct: git://git.netfilter.org/nfct You also have to get iptables with -j CT --timeout support.

2012-03-07DMA: sa11x0: add SA-11x0 DMA driverRussell King1-0/+24
Add support for the SA-11x0 DMA driver, which replaces the private API version in arch/arm/mach-sa1100/dma.c. We model this as a set of virtual DMA channels, one for each request signal, and assign the virtual DMA channel to a physical DMA channel when there is work to be done. This allows DMA users to claim their channels, and hold them while not in use, without affecting the availability of the physical channels. Another advantage over this approach, compared to the private version, is that a channel can be reconfigured on the fly without having to release and re-request it - which for the IrDA driver, allows us to use DMA for SIR mode transmit without eating up three physical channels. As IrDA is half-duplex, we actually only need one physical channel, and this architecture allows us to achieve that. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

While doing the work for commit a6f7feae6d ("IB/mlx4: pass SMP vendor-specific attribute MADs to firmware") we realized that the firmware would respond on all sorts of vendor-specific MADs. Therefore commit 97285b7817 ("mlx4_core: Add extended port capabilities support") adds redundant code into the driver, since there's no real reaon to maintain the extended capabilities of the port, as they can be queried on demand (e.g the FDR10 capability).

2012-03-06mfd: Add ab8500 version detection and enforcingLinus Walleij2-8/+58
There are currently four different versions of the AB8500 around: AB8500, AB8505, AB9540 and AB8540. Unfortunately: - Some of the chips (AB8500, AB8505, AB9540) cannot read the AB8500_REV_REG register but return errors - Some of them have the same ID value in the hardware register AB8500_REV_REV, for example the first versions of AB8505 and AB9540 have 0xFF in this register - just like the AB8500. So we need to be able to enforce a certain version from the platform. We do this by using the id of the platform device that provides the read/write functions.
