Multiple mappings can map to the same physical pages of an object (aliasing). These mappings (also referred to as persistent mappings) will be persistent across multiple GPU submissions (execbuf calls) issued by the UMD, without user having to provide a list of all required mappings during each submission (as required by older execbuf mode). This patch series support VM_BIND version 1, as described by the param I915_PARAM_VM_BIND_VERSION. Add new execbuf3 ioctl (I915_GEM_EXECBUFFER3) which only works in vm_bind mode. The vm_bind mode only works with this new execbuf3 ioctl. The new execbuf3 ioctl will not have any execlist support and all the legacy support like relocations etc., are removed.
