[Intel-gfx] i915_gem_init_aliasing_ppgtt() loop after 55a254ac63a3ac1867d1501030e7fba69c7d4aeb

[Konstantin Belousov]

Hi,
it seems that the loop in i915_gem_init_aliasing_ppgtt() over pd_entries
that calculates pt_addr does nothing after the commit 55a254ac in the
!dmar case. Would it be better to move needs_dmar check over the whole
loop ?
