radeonsi: expand constbuf 0 address correctly to fix Vega10 hangs
This is only required with the latest libdrm. This fixes 32-bit support with high addresses. (and possibly 64-bit support too because the high bits need to be masked out) Acked-by: Christian König <[email protected]> Acked-by: Alex Deucher <[email protected]>
