This new version picks the suggestion from Michał Winiarski related to v3 [1].
48-bit virtual address range will be enabled in i915 soon, but some objects must be referenced by 32-bit offsets. These patches use a new kernel flag to specify if this restriction applies or not.
I'm sending these patches to comply with the i915 merge process. Once the kernel patch is merged, I'll make a new libdrm release and address the mesa build dependency.
