With the global kmem_cache shrink infrastructure gone there's nothing special and we can convert them over.
I'm doing this split up into each patch because there's quite a bit of noise with removing the static global.slab_vmas to just a slab_vmas.
We have to keep i915_drv.h include in i915_globals otherwise there's nothing anymore that pulls in GEM_BUG_ON.
v2: Make slab static (Jason, 0day)
