Subject: Replace some structure-based batch preparation with plain OUT_BATCH.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1f7378ee465eba8d82d224a7bf835e38c5ab6ee2;p=mesa.git

Replace some structure-based batch preparation with plain OUT_BATCH.

OUT_BATCH is far more amenable to the upcoming relocations being done for TTM
support.
