2018-03-21drm/i915: Specify which engines to reset following semaphore/event lockupsChris Wilson
If the GPU is stuck waiting for an event or for a semaphore, we need to reset the GPU in order to recover. We have to tell the reset routine which engines we want reset, but we were still using the old interface and declaring it as "not-fatal".

2018-03-21ath9k_htc: use non-QoS NDP for AP probingJohannes Berg
When switching mac80211 to use QoS NDP, it turned out that ath9k_htc is somehow broken by this, e.g. see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891060. Fix this by using the new mac80211 flag to go back to the old, incorrect, behaviour for this driver.

Set the wmediumd to the net's wmediumd when the radio gets created. Radios created after HWSIM_CMD_REGISTER don't currently get their data->wmediumd set and the userspace would need to reconnect to netlink to be able to call HWSIM_CMD_REGISTER again. Alternatively I think data->netgroup and data->wmedium could be replaced with a pointer to hwsim_net.

2018-03-21drm/vmwgfx: Fix a destoy-while-held mutex problem.Thomas Hellstrom
When validating legacy surfaces, the backup bo might be destroyed at surface validate time. However, the kms resource validation code may have the bo reserved, so we will destroy a locked mutex. While there shouldn't be any other users of that mutex when it is destroyed, it causes a lock leak and thus throws a lockdep error. Fix this by having the kms resource validation code hold a reference to the bo while we have it reserved. We do this by introducing a validation context which might come in handy when the kms code is extended to validate multiple resources or buffers.

2018-03-21drm/vmwgfx: Fix black screen and device errors when running without fbdevThomas Hellstrom
When we are running without fbdev, transitioning from the login screen to X or gnome-shell/wayland will cause a vt switch and the driver will disable svga mode, losing all modesetting resources. However, the kms atomic state does not reflect that and may think that a crtc is still turned on, which will cause device errors when we try to bind an fb to the crtc, and the screen will remain black. Fix this by turning off all kms resources before disabling svga mode. Cc: <stable@vger.kernel.org> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>

This is a fairly exotic case these days, hence why it is not flagged for stable. There is also support for dedicating one of the overlay planes to serve as a hardware cursor on older Tegra that did support hardware cursors but not RGBA formats for it. Planes will now also export the IN_FORMATS property by supporting the various block-linear tiling modifiers for RGBA pixel formats. Other than that, there's a bit of cleanup of DMA API abuse, use of the private object infrastructure for global state (rather than subclassing atomic state objects) and an implementation of ->{begin,end}_cpu_access callbacks for PRIME exported buffers, which allow users to perform cache maintenance on these buffers. * tag 'drm/tegra/for-4.17-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: prime: Implement ->{begin,end}_cpu_access() drm/tegra: gem: Map pages via the DMA API drm/tegra: hub: Use private object for global state drm/tegra: fb: Properly support linear modifier drm/tegra: plane: Support format modifiers drm/tegra: dc: Dedicate overlay plane to cursor on older Tegra's drm/tegra: plane: Make tegra_plane_get_overlap_index() static drm/tegra: fb: Implement ->fb_mmap() callback drm/tegra: gem: Make __tegra_gem_mmap() available more widely drm/tegra: gem: Reshuffle declarations

2018-03-20RDMA/ucma: Ensure that CM_ID exists prior to access itLeon Romanovsky
Prior to access UCMA commands, the context should be initialized and connected to CM_ID with ucma_create_id(). In case user skips this step, he can provide non-valid ctx without CM_ID and cause to multiple NULL dereferences. Also there are situations where the create_id can be raced with other user access, ensure that the context is only shared to other threads once it is fully initialized to avoid the races.
