The semantics of this bit are wrong.  If the suspended state is not 
available, the old hwcap bit needs to be cleared, and a new flag needs 
to be set which documents the availability of the different for, of 
transactional memory.  Otherwise, old applications which assume the 
presence of the suspended state when the old hwcap bit is set will break.

(I think we should have this discussion on the kernel list.)

Thanks,
