What is "flush" is supposed to exactly mean here? If specifically any of the two formers (the latter is obviously the other flag), then I suggest using the respective name, or otherwise if it is meant to be generic "do what is needed", then perhaps "synchronize" will work, like with the name of the SYNCI instruction?
