2012-07-11iommu: Add domain-attribute handlersJoerg Roedel
This patch introduces an extension to the iommu-api to get and set attributes for an iommu_domain. Two functions are introduced for this: * iommu_domain_get_attr() * iommu_domain_set_attr() These functions will be used to make the iommu-api suitable for GART-like IOMMUs and to implement hardware-specifc api-extensions.

2012-07-11KVM: Fix device assignment threaded irq handlerAlex Williamson
The kernel no longer allows us to pass NULL for the hard handler without also specifying IRQF_ONESHOT. IRQF_ONESHOT imposes latency in the exit path that we don't need for MSI interrupts. Long term we'd like to inject these interrupts from the hard handler when possible. In the short term, we can create dummy hard handlers that return us to the previous behavior.

2012-07-11ixgbe: Merge RSS and flow director ring register caching and configurationAlexander Duyck
There are really only 3 modes that can control the number of queues. Those are RSS, DCB, and VMDq/SR-IOV. Currently we have things much more broken up than they need to be for how we are configuring the rings. In order to try and straiten some of this out I am going to start merging similar functionality into single functions. To start with I am merging the Flow Director ring configuration into the RSS ring configuration since Flow Director cannot function with DCB or SR-IOV.

2012-07-11ixgbe: Clean up a useless switch statement and dead code in configure_srrctlAlexander Duyck
This patch replaces a switch statement for an 82598 workaround with an if statement that only applies to 82598. In addition I am pulling out several dead pieces of code and instead of reading the SRRCTL register and then modifying it we are just writing a value which we generate from scratch. Finally I am also removing any drop enable related code since that was moved to a function of its own.

2012-07-11ixgbe: Add feature offset value to ring featuresAlexander Duyck
The mask value for ring features was overloaded for FCoE which can lead to some confusion. In order to avoid any confusion I am splitting the mask value and adding an offset value. This can be used for the start of the FCoE rings, and in the future I hope to use it to store the start of the registers for SR-IOV.

2012-07-11ixgbe: Add upper limit to ring featuresAlexander Duyck
We are currently using indices to indicate the upper limit on a ring feature. However since we can switch back and forth on features such as DCB and that has effects on other features such as RSS it is preferable to instead store the upper limit separate from the current value for the number of rings related to the feature.

2012-07-11ixgbe: count q_vectors instead of MSI-X vectorsAlexander Duyck
It makes much more sense for us to count q_vectors instead of MSI-X vectors. We were using num_msix_vectors to find the number of q_vectors in multiple places. This was wasteful since we only had one place that actually needs the number of MSI-X vectors and that is in slow path.

Some power systems do not have legacy ISA devices. So, /dev/port is not a valid interface on these systems.

2012-07-10net: Fix memory leak - vlan_info structAmir Hanania
In driver reload test there is a memory leak. The structure vlan_info was not freed when the driver was removed. It was not released since the nr_vids var is one after last vlan was removed. The nr_vids is one, since vlan zero is added to the interface when the interface is being set, but the vlan zero is not deleted at unregister. Fix - delete vlan zero when we unregister the device.
