If its like whoever merges first then it should be ok to keep it this way and you can add my r-o-b. Or else if we should adjust now! Thanks for the heads up. I think whoever gets in first gets the lowest bit and fixup the later series in the following post or at merge time.

Add the DRM_XE_QUERY_CONFIG_FLAG_HAS_CPU_ADDR_MIRROR device query flag, which indicates whether the device supports CPU address mirroring. The intent is for UMDs to use this query to determine if a VM can be set up with CPU address mirroring. This flag is implemented by checking if the device supports GPU faults.
