commit 65500f98e5ec747fda8877ffad40c053b9abdbb2 (HEAD)
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Jun 17 12:12:30 2019 +0100

    i915/gem_ctx_shared: Check for a large enough hole in the GTT
    
    In the exec-shared-gtt test, we cheekily try to reference an object we
    placed in the GTT in an earlier execbuf (and avoid declaring it in the
    later call). For a global GTT, where there may be existing objects, we
    have to find a hole large enough to fit both and avoid and implicit
    guard pages.
