Currently sys_sigreturn() is TM unaware. Therefore, if we take a 32 bit signal without SIGINFO (non RT) inside a transaction, on signal return we don't restore the signal frame correctly. This checks if the signal frame being restoring is an active transaction, and if so, it copies the additional state to ptregs so it can be restored.
