2020-11-02drm/nouveau/ttm: Add limits.hMaxime Ripard
It seems that a recent commit broke the nouveau compilation when swiotlb is disabled (which is the case on our ARM defconfig for example). Daniel says """ Since the proper fix is maybe stuck in the usual "drm abuses swiotlb internals" bikeshed, maybe best if we push a fix to including limits.h in nouveau and call it done? """ So let's go down the simplest path to fix our build, and goes back to it later if needed.

2020-11-02drm/nouveu: fix swiotlb includeChristian König
The check for swiotlb has moved to nouveu_ttm.c, but we forgot to move the include as well. This blows up only when merged with linux-next, not sure why drm-misc-next works stand alone.

2020-09-03drm/nouveau: move io_reserve_lru handling into the driver v5Christian König
While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. v2: don't call ttm_bo_unmap_virtual in nouveau_ttm_io_mem_reserve v3: rebased and use both base and offset in the check v4: fix small typos and test the patch v5: rebased and keep the mem.bus init in TTM.

Rename the embedded struct vma_offset_manager, new name is _vma_manager. ttm_bo_device.vma_manager changed to a pointer. The ttm_bo_device_init() function gets an additional vma_manager argument which allows to initialize ttm with a different vma manager. When passing NULL the embedded _vma_manager is used.
