2016-05-20drm/nouveau/devinit/gf100: make devinit on resume saferAlexandre Courbot
In case of successful suspend, devinit will have to be run and this is the behavior currently hardcoded. However, as FD bug 94725 suggests, there might be cases where runtime suspend leaves the GPU powered, and in such cases devinit should not be run on resume. On GF100+ we have a reliable way to know whether we need to run devinit. Use it instead of blindly trusting the flag set by nvkm_devinit_fini(). The code around the NvForcePost also needs to be slightly reworked in order to keep working.

2016-05-18drm/tegra: Fix crash caused by reference count imbalanceJon Hunter
Commit d2307dea14a4 ("drm/atomic: use connector references (v3)") added reference counting for DRM connectors and this caused a crash when exercising system suspend on Tegra114 Dalmore. The Tegra DSI driver implements a Tegra specific function, tegra_dsi_connector_duplicate_state(), to duplicate the connector state and destroys the state using the generic helper function, drm_atomic_helper_connector_destroy_state(). Following commit d2307dea14a4 ("drm/atomic: use connector references (v3)") there is now an imbalance in the connector reference count because the Tegra function to duplicate state does not take a reference when duplicating the state information. However, the generic helper function to destroy the state information assumes a reference has been taken and during system suspend, when the connector state is destroyed, this leads to a crash because we attempt to put the reference for an object that has already been freed. Fix this by calling __drm_atomic_helper_connector_duplicate_state() from tegra_dsi_connector_duplicate_state() to ensure that we take a reference on a connector if crtc is set. Note that this will also copy the connector state a 2nd time, but this should be harmless. By fixing tegra_dsi_connector_duplicate_state() to take a reference, although a crash was no longer seen, it was then observed that after each system suspend-resume cycle, the reference would be one greater than before the suspend-resume cycle. Following commit d2307dea14a4 ("drm/atomic: use connector references (v3)"), it was found that we also need to put the reference when calling the function tegra_dsi_connector_reset() before freeing the state. Fix this by updating tegra_dsi_connector_reset() to call the function __drm_atomic_helper_connector_destroy_state() in order to put the reference for the connector.

2016-05-17drm/fb_helper: Fix references to dev->mode_config.num_connectorLyude
During boot, MST hotplugs are generally expected (even if no physical hotplugging occurs) and result in DRM's connector topology changing. This means that using num_connector from the current mode configuration can lead to the number of connectors changing under us. This can lead to some nasty scenarios in fbcon: - We allocate an array to the size of dev->mode_config.num_connectors. - MST hotplug occurs, dev->mode_config.num_connectors gets incremented. - We try to loop through each element in the array using the new value of dev->mode_config.num_connectors, and end up going out of bounds since dev->mode_config.num_connectors is now larger then the array we allocated. fb_helper->connector_count however, will always remain consistent while we do a modeset in fb_helper. Note: This is just polish for 4.7, Dave Airlie's drm_connector refcounting fixed these bugs for real. But it's good enough duct-tape for stable kernel backporting, since backporting the refcounting changes is way too invasive.

2016-05-17drm/i915/fbdev: Fix num_connector references in intel_fb_initial_config()Lyude
During boot time, MST devices usually send a ton of hotplug events irregardless of whether or not any physical hotplugs actually occurred. Hotplugs mean connectors being created/destroyed, and the number of DRM connectors changing under us. This isn't a problem if we use fb_helper->connector_count since we only set it once in the code, however if we use num_connector from struct drm_mode_config we risk it's value changing under us. On top of that, there's even a chance that dev->mode_config.num_connector != fb_helper->connector_count. If the number of connectors happens to increase under us, we'll end up using the wrong array size for memcpy and start writing beyond the actual length of the array, occasionally resulting in kernel panics. Note: This is just polish for 4.7, Dave Airlie's drm_connector refcounting fixed these bugs for real. But it's good enough duct-tape for stable kernel backporting, since backporting the refcounting changes is way too invasive.

This adds one more argument to of_fdt_unflatten_tree() to specify the parent node of the FDT blob that is going to be unflattened.

2016-05-13drm/amdgpu: create fence slab once when amdgpu module init.Rex Zhu
This avoids problems with multiple GPUs. For example, if the first GPU failed before amdgpu_fence_init() was called, amdgpu_fence_slab_ref is still 0 and it will get decremented in amdgpu_fence_driver_fini(). This will lead to a crash during init of the second GPU since amdgpu_fence_slab_ref is not 0. v2: add functions for init/exit instead of moving the variables into the driver.
