2016-10-07libnvdimm, namespace: allow multiple pmem-namespaces per region at scan timeDan Williams
If label scanning finds multiple valid pmem namespaces allow them to be surfaced rather than fail namespace scanning. Support for creating multiple namespaces per region is saved for a later patch. Note that this adds some new error messages to clarify which of the pmem namespaces in the set are potentially impacted by invalid labels. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2016-10-06xen-netback: retire guest rx side prefix GSO featurePaul Durrant
As far as I am aware only very old Windows network frontends make use of this style of passing GSO packets from backend to frontend. These frontends can easily be replaced by the freely available Xen Project Windows PV network frontend, which uses the 'default' mechanism for passing GSO packets, which is also used by all Linux frontends. NOTE: Removal of this feature will not cause breakage in old Windows frontends. They simply will no longer receive GSO packets - the packets instead being fragmented in the backend.

We really do need to be using the halved V fields. I had been confused by the code I was using as a reference because it stored halved vsync fields but not halved vdisplay, so it looked like I only needed to divide vdisplay by 2. This reverts part of Mario's timestamping fixes that prevented CRTC_HALVE_V from applying, and instead adjusts the timestamping code to not use the crtc field in that case. Fixes locking of 1920x1080x60i on my Dell 2408WFP. There are black bars on the top and bottom, but I suspect that might be an under/overscan flags problem as opposed to video timings.

On Pi0/1/2, we use an external GPIO line for hotplug detection, since the HDMI_HOTPLUG register isn't connected to anything. However, with the Pi3 the HPD GPIO line has moved off to a GPIO expander that will be tricky to get to (the firmware is constantly polling the expander using i2c0, so we'll need to coordinate with it). As a stop-gap, if we don't have a GPIO line, use an EDID probe to detect connection. Fixes HDMI display on the pi3. Signed-off-by: Eric Anholt <eric@anholt.net>

2016-10-06IB/rxe: improved debug prints & code cleanupParav Pandit
1. Debugging qp state transitions and qp errors in loopback and multiple QP tests is difficult without qp numbers in debug logs. This patch adds qp number to important debug logs. 2. Instead of having rxe: prefix in few logs and not having in few logs, using uniform module name prefix using pr_fmt macro. 3. Code cleanup for various warnings reported by checkpatch for incomplete unsigned data type, line over 80 characters, return statements.

2016-10-06rdma_rxe: Ensure rdma_rxe init occurs at correct timeStephen Bates
There is a problem when CONFIG_RDMA_RXE=y and CONFIG_IPV6=y. This results in the rdma_rxe initialization occurring before the IPv6 services are ready. This patch delays the initialization of rdma_rxe until after the IPv6 services are ready. This fix is based on one proposed by Logan Gunthorpe on a much older code base.

2016-10-06IB/{rxe,core,rdmavt}: Fix kernel crash for reg MRParav Pandit
This patch fixes below kernel crash on memory registration for rxe and other transport drivers which has dma_ops extension. IB/core invokes ib_map_sg_attrs() in generic manner with dma attributes which is used by mlx5 and mthca adapters. However in doing so it ignored honoring dma_ops extension of software based transports for sg map/unmap operation. This results in calling dma_map_sg_attrs of hardware virtual device resulting in crash for null reference. We extend the core to support sg_map/unmap_attrs and transport drivers to implement those dma_ops callback functions. Verified usign perftest applications.

2016-10-06IB/rxe: Fix sending out loopback packet on netdev interface.Parav Pandit
Both prepare4 and prepare6 sets loopback mask in pkt_info structure instance of skb. The xmit_packet and other requester side functions use a pkt_info struct from the stack without the proper mask. This results in sending out the packet to the actual netdev device and loopback functionality is broken. Modify prepare() to pass its correctly marked pkt_info struct to prepare4() and prepare6() instead of them using SKB_TO_PKT(skb) and getting an incorrectly set mask.

If this happens (and it recently did), we free a structure while part of it is still in use, which results in non-obvious crashes. The way it's detached is not trivial (DRM core has to call the connector .destroy callback and things must be torn down in the right order), so better detect it and warn early.
