[Intel-gfx] [PATCH v2 05/11] drm/i915: move gem_context slab to direct module init/exit

[Daniel Vetter <daniel.vetter@ffwll.ch>]

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_luts to just a
slab_luts.

v2: Make slab static (Jason, 0day)
