On GFX rings align_mask is\n0xff, so the loop wrote 256 dwords into a 64-byte buffer, causing a\nkernel page fault.\n\nThe IB only needs to be a minimal NOP shell to schedule the job; the\ncleaner shader itself is emitted on the ring via emit_cleaner_shader().\nFill 16 dwords to match the allocation.\n\nv2: Use ib_size_dw variable (Lijo)\n\n(cherry picked from commit bf21af331ebf72d0935fd70c73192414a422c03a)"
