[Intel-gfx] [PATCH] drm/i915/dmabuf: don't trust the dma_buf->size

[Intel-gfx] [PATCH] drm/i915/dmabuf: don't trust the dma_buf->size

[Matthew Auld]

At least for the time being, we need to limit our object sizes such that
the number of pages can fit within a 32b signed int. It looks like we
should also apply the same restriction to any imported dma-buf.

Just to be a pain, let's consolidate these together so we don't forget.

i915_gem.h or i915_gem_object.h?
