2014-12-04memory: Add NVIDIA Tegra memory controller supportThierry Reding
The memory controller on NVIDIA Tegra exposes various knobs that can be used to tune the behaviour of the clients attached to it. Currently this driver sets up the latency allowance registers to the HW defaults. Eventually an API should be exported by this driver (via a custom API or a generic subsystem) to allow clients to register latency requirements. This driver also registers an IOMMU (SMMU) that's implemented by the memory controller. It is supported on Tegra30, Tegra114 and Tegra124 currently. Tegra20 has a GART instead. The Tegra SMMU operates on memory clients and SWGROUPs. A memory client is a unidirectional, special-purpose DMA master. A SWGROUP represents a set of memory clients that form a logical functional unit corresponding to a single device. Typically a device has two clients: one client for read transactions and one client for write transactions, but there are also devices that have only read clients, but many of them (such as the display controllers). Because there is no 1:1 relationship between memory clients and devices the driver keeps a table of memory clients and the SWGROUPs that they belong to per SoC. Note that this is an exception and due to the fact that the SMMU is tightly integrated with the rest of the Tegra SoC. The use of these tables is discouraged in drivers for generic IOMMU devices such as the ARM SMMU because the same IOMMU could be used in any number of SoCs and keeping such tables for each SoC would not scale.

2014-12-04kvm: optimize GFN to memslot lookup with large slots amountIgor Mammedov
Current linear search doesn't scale well when large amount of memslots is used and looked up slot is not in the beginning memslots array. Taking in account that memslots don't overlap, it's possible to switch sorting order of memslots array from 'npages' to 'base_gfn' and use binary search for memslot lookup by GFN. As result of switching to binary search lookup times are reduced with large amount of memslots. Following is a table of search_memslot() cycles during WS2008R2 guest boot. boot, boot + ~10 min mostly same of using it, slot lookup randomized lookup max average average cycles cycles cycles 13 slots : 1450 28 30 13 slots : 1400 30 40 binary search 117 slots : 13000 30 460 117 slots : 2000 35 180 binary search Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-12-04PM / Domains: Initial PM clock support for genpdUlf Hansson
It's quite common for PM domains to use PM clocks. Typically from SOC specific code, the per device PM clock list is created and pm_clk_suspend|resume() are invoked to handle clock gating/ungating. A step towards consolidation is to integrate PM clock support into genpd, which is what this patch does. In this initial step, the calls to the pm_clk_suspend|resume() are handled within genpd, but the per device PM clock list still needs to be created from SOC specific code. It seems reasonable to have gendp to handle that as well, but that left to future patches to address. It's not every users of genpd that are keen on using PM clocks, thus we need to provide this a configuration option for genpd. Therefore let's add flag field in the genpd struct to keep this information and define a new GENDP_FLAG_PM_CLK bit for it.

2014-12-03of: Drop ->next pointer from struct device_nodeGrant Likely
The ->next pointer in struct device_node is a hanger-on from when it was used to iterate over the whole tree by a particular device_type property value. Those days are long over, but the fdt unflattening code still uses it to put nodes in the unflattened tree into the same order as node in the flat tree. By reworking the unflattening code to reverse the list after unflattening all the children of a node, the pointer can be dropped which gives a small amount of memory savings.

2014-12-02bridge: add API to notify bridge driver of learned FBD on offloaded deviceScott Feldman
When the swdev device learns a new mac/vlan on a port, it sends some async notification to the driver and the driver installs an FDB in the device. To give a holistic system view, the learned mac/vlan should be reflected in the bridge's FBD table, so the user, using normal iproute2 cmds, can view what is currently learned by the device. This API on the bridge driver gives a way for the swdev driver to install an FBD entry in the bridge FBD table. (And remove one).
