      drm/i915: correct the calculation of first_pd_entry_in_global_pt · 43b27290
      Zhang, Xiong Y authored
      When ppgtt is enabled, dev_priv->gtt.total has excluded the gtt space
      occupied by ppgtt table in i915_gem_init_global_gtt() function. So the
      calculation of first_pd_entry_in_global_pt doesn't need to subtract
      I915_PPGTT_PD_ENTRIES again. Or else PPGTT directory table will be
      destroyed by global gtt allocation.
      
      This regression has been introduced in

          drm/i915: remove intel_gtt structure
      
      The breakage is pretty subtile since the old gtt_total_entries
      included the pde range, whereas the new on did not.
