Discontinue any use of 'swp(b)' on PP5020. While clocking is stable, some testing revealed this instruction can still cause problems without concurrent access. Make sure mpegplayer is safe while not using spinlock (no longer atomic) between cores to protect the stream byte counters - use nonwrapping head and tail pointers.
