commit 5f12b80a0b42da253691ca03828033014bb786eb
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Oct 3 13:45:15 2016 +0100

    drm/i915: Unalias obj->phys_handle and obj->userptr
    
    We use obj->phys_handle to choose the pread/pwrite path, but as
    obj->phys_handle is a union with obj->userptr, we then mistakenly use
    the phys_handle path for userptr objects within pread/pwrite.
