2016-11-15drm/irq: Unexport drm_vblank_on/offDaniel Vetter
Only remaining use was in amdgpu, and trivial to convert over to drm_crtc_vblank_* variants.

2016-11-15drm/irq: Make drm_vblank_pre/post_modeset internalDaniel Vetter
Now that all drivers are switched over to drm_crtc_vblank_on/off we can relegate pre/post_modeset to the purely drm_irq.c internal role of supporting old ums userspace. As usual switch to the drm_legacy_ prefix to make it clear this is for old drivers only. v2: Rebase on top of Thierry's s/int crtc/unsigned int pipe/ changes.

2016-11-15Revert "drm: Add and handle new aspect ratios in DRM layer"Ville Syrjälä
This reverts commit a68362fe3e84fcbedd49939aa200519aa5410135. Adding new mode flags willy nilly breaks existing userspace. We need to coordinate this better, potentially with a new client cap that only exposes the aspect ratio flags when userspace is prepared for them (similar to what we do with stereo 3D modes).

2016-11-12drm: move allocation out of drm_get_format_name()Eric Engestrom
The function's behaviour was changed in 90844f00049e, without changing its signature, causing people to keep using it the old way without realising they were now leaking memory. Rob Clark also noticed it was also allocating GFP_KERNEL memory in atomic contexts, breaking them. Instead of having to allocate GFP_ATOMIC memory and fixing the callers to make them cleanup the memory afterwards, let's change the function's signature by having the caller take care of the memory and passing it to the function. The new parameter is a single-field struct in order to enforce the size of its buffer and help callers to correctly manage their memory.

2016-10-29net/mlx5: PCI error recovery health care simulationMohamad Haj Yahia
In case that the kernel PCI error handlers are not called, we will trigger our own recovery flow. The health work will give priority to the kernel pci error handlers to recover the PCI by waiting for a small period, if the pci error handlers are not triggered the manual recovery flow will be executed. We don't save pci state in case of manual recovery because it will ruin the pci configuration space and we will lose dma sync.

2016-10-29net/mlx5: Fix race between PCI error handlers and health workMohamad Haj Yahia
Currently there is a race between the health care work and the kernel pci error handlers because both of them detect the error, the first one to be called will do the error handling. There is a chance that health care will disable the pci after resuming pci slot. Also create a separate WQ because now we will have two types of health works, one for the error detection and one for the recovery.
