[Intel-gfx] [PATCH libdrm v4 0/2] 48-bit virtual address support in i915

This new version picks the suggestion from MichaƂ 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.
