2017-03-27drm/i915: Mark manually wedged engines as guiltyChris Wilson
Use the incoming value from debugfs/i915_wedged to select which engines to marked as guilty in order to force us to reset those requests (required to quickly bypass simulated hangs).

2017-03-27drm/i915: Refactor tests for validity of RING_TAILChris Wilson
Whilst I like having the assertions clearly visible in the code, they are quite repetitious! As we find new limits we want to incorporate into the set of assertions, it make sense to refactor them to a common routine. v2: Add a guc holdout.

2017-03-27drm/i915: Assert that the request->tail fits within the ringChris Wilson

2017-03-27drm/i915/execlists: Wrap tail pointer after reset tweakingChris Wilson
If the request->wa_tail is 0 (because it landed exactly on the end of the ringbuffer), when we reconstruct request->tail following a reset we fill in an illegal value (-8 or 0x001ffff8). As a result, RING_HEAD is never able to catch up with RING_TAIL and the GPU spins endlessly. If the ring contains a couple of breadcrumbs, even our hangcheck is unable to catch the busy-looping as the ACTHD and seqno continually advance. v2: Move the wrap into a common intel_ring_wrap().

2017-03-27drm/i915: Use i9xx_check_plane_surface() for sprite planes as wellVille Syrjälä
All the pre-SKL sprite planes compute the x/y/tile offsets in a similar way. There are a couple of minor differences but the primary planes have those as well.

Pull audit fix from Paul Moore: "We've got an audit fix, and unfortunately it is big. While I'm not excited that we need to be sending you something this large during the -rcX phase, it does fix some very real, and very tangled, problems relating to locking, backlog queues, and the audit daemon connection. This code has passed our testsuite without problem and it has held up to my ad-hoc stress tests (arguably better than the existing code), please consider pulling this as fix for the next v4.11-rcX tag" * 'stable-4.11' of git://git.infradead.org/users/pcmoore/audit: audit: fix auditd/kernel connection state tracking

2017-03-24RDMA/iser: Fix possible mr leak on device removal eventSagi Grimberg
When the rdma device is removed, we must cleanup all the rdma resources within the DEVICE_REMOVAL event handler to let the device teardown gracefully. When this happens with live I/O, some memory regions are occupied. Thus, track them too and dereg all the mr's. We are safe with mr access by iscsi_iser_cleanup_task.

2017-03-24IB/device: Convert ib-comp-wq to be CPU-boundSagi Grimberg
This workqueue is used by our storage target mode ULPs via the new CQ API. Recent observations when working with very high-end flash storage devices reveal that UNBOUND workqueue threads can migrate between cpu cores and even numa nodes (although some numa locality is accounted for). While this attribute can be useful in some workloads, it does not fit in very nicely with the normal run-to-completion model we usually use in our target-mode ULPs and the block-mq irq<->cpu affinity facilities. The whole block-mq concept is that the completion will land on the same cpu where the submission was performed. The fact that our submitter thread is migrating cpus can break this locality. We assume that as a target mode ULP, we will serve multiple initiators/clients and we can spread the load enough without having to use unbound kworkers. Also, while we're at it, expose this workqueue via sysfs which is harmless and can be useful for debug.

2017-03-24IB/rxe: increment msn only when completing a requestDavid Marchand
According to C9-147, MSN should only be incremented when the last packet of a multi packet request has been received. "Logically, the requester associates a sequential Send Sequence Number (SSN) with each WQE posted to the send queue. The SSN bears a one- to-one relationship to the MSN returned by the responder in each re- sponse packet. Therefore, when the requester receives a response, it in- terprets the MSN as representing the SSN of the most recent request completed by the responder to determine which send WQE(s) can be completed."

Avoid that the following error message is reported on the console while loading an RDMA driver with I/O MMU support enabled: DMAR: Allocating domain for mlx5_0 failed Ensure that DMA mapping operations that use to_pci_dev() to access to struct pci_dev see the correct PCI device. E.g. the s390 and powerpc DMA mapping operations use to_pci_dev() even with I/O MMU support disabled. This patch preserves the following changes of the DMA mapping updates patch series: - Introduction of dma_virt_ops. - Removal of ib_device.dma_ops. - Removal of struct ib_dma_mapping_ops. - Removal of an if-statement from each ib_dma_*() operation. - IB HW drivers no longer set dma_device directly.
