BRW_NEW_CONTEXT is the flag for "we might have lost our context because everything got reprogrammed." BRW_NEW_BATCH is the flag for "we have to program it again with a new batch for other reasons (e.g. relocations ensuring that your buffer is present). The intent was that when we get MI_SET_CONTEXT, we just stop flagging BRW_NEW_CONTEXT per batch.
