* it wants in its register space, and we calculate those areas here under the
- * BRW_NEW_CURBE_OFFSETS state flag. The brw_urb.c allocation will control
+ * BRW_NEW_PUSH_CONSTANT_ALLOCATION state flag. The brw_urb.c allocation will control
* how many CURBEs can be loaded into the hardware at once before a pipeline
