commit 8f5e2b306b4e26db0ec65e0a27b232b179c9122b
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Sep 2 05:02:43 2019 +0100

    drm/i915: Restrict the aliasing-ppgtt to the size of the ggtt
    
    The aliasing-ppgtt is not allowed to be smaller than the ggtt, nor
    should we advertise it as being any bigger, or else we may get sued for
    false advertisement.
    
    Testcase: igt/gem_exec_big
