Dave Gordon 731f74c5c6 drm/i915: tweak gen6_for_{each_pde, all_pdes} macros ... Gen8 versions of these macros were updated a few months ago (e8ebd8e drm/i915: eliminate 'temp' in gen8_for_each macros) originally because at least one iterator could generate an out of bounds access, but also because eliminating the 'temp' parameter generated smaller and faster code. Matthew Auld recently noticed the same problem with the gen6 versions and provided a patch https://lists.freedesktop.org/archives/intel-gfx/2016-June/099334.html but while we're changing these, we might as well make them as much like the gen8 versions as possible, including the style of using "&& (..., true)" rather than ": (..., 1) : 0", and of course eliminating the redundant 'temp'. Furthermore, the "all_pdes" version is only used in one place, so we can improve code efficiency by changing both the macro parameters and the calling code to reduce extra dereferences.
