PLO CSDST and CSTST are *extremely* useful for queue and linked list
manipulation in multi-ASID multi-TCB environments. The key to their use is to
have a lock word counter that the caller increments and then prepares the new
values in other regs. When it comes time to actually atomically update

If you truly need a triple compare and swap then PLO will not help you. But if
you need a disjoint double compare and swap, you use the compare-and-swap
field as a counter and then you con do a compare swap and double store.
