The mm changes in there we premature and not fully ack or reviewed by core mm folks, I dropped the ball by merging them via this tree, so lets take em all back out. Signed-off-by: Dave Airlie

drm/ttm: TTM fault handler helpers

2019-06-18T13:19:34Z

With the vmwgfx dirty tracking, the default TTM fault handler is not completely sufficient (vmwgfx need to modify the vma->vm_flags member, and also needs to restrict the number of prefaults). We also want to replicate the new ttm_bo_vm_reserve() functionality So start turning the TTM vm code into helpers: ttm_bo_vm_fault_reserved() and ttm_bo_vm_reserve(), and provide a default TTM fault handler for other drivers to use.

drm/ttm: Allow the driver to provide the ttm struct vm_operations_struct

2019-06-18T13:19:34Z

Add a pointer to the struct vm_operations_struct in the bo_device, and assign that pointer to the default value currently used. The driver can then optionally modify that pointer and the new value can be used for each new vma created. Cc: "Christian König" Signed-off-by: Thomas Hellstrom Reviewed-by: Christian König

drm/ttm: fix ttm_bo_unreserve

Since we now keep BOs on the LRU we need to explicitely remove them from the LRU now after they are pinned. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/ttm: Make LRU removal optional v2

2019-05-31T15:39:34Z

We are already doing this for DMA-buf imports and also for amdgpu VM BOs for quite a while now. If this doesn't run into any problems we are probably going to stop removing BOs from the LRU altogether. v2: drop BUG_ON from ttm_bo_add_to_lru Signed-off-by: Christian König Reviewed-by: Chunming Zhou Tested-by: Pierre-Eric Pelloux-Prayer Signed-off-by: Alex Deucher

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.

drm/ttm: fix re-init of global structures

2019-04-19T16:11:20Z

When a driver unloads without unloading TTM we don't correctly clear the global structures leading to errors on re-init. Next step should probably be to remove the global structures and kobjs all together, but this is tricky since we need to maintain backward compatibility.

Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same value. The only exception is vboxvideo, which is being converted to the new offset by this patch.
