One more question (according to assembly stuff)
what happen when the two cpu excute at the same time the same:

 ldcw,co 0(%r3),%r28 

here it seems that r3 are all == r26 == 000000001049ee80 

(the idea is that: if the two cpu execute the same insn of the same loop at
the same time they would also excecute at the same time the (2) previous insn) 

(unfortunately I don't understand all the details of the ldcw description in
parisc-2.0.pdf ;-( )

Sorry, a second question always about 
static __inline__ __attribute__((always_inline)) void
__raw_read_lock(raw_rwlock_t *rw)
{
 __raw_spin_lock_flags(&rw->lock, 0);

 rw->counter++;

 __raw_spin_unlock(&rw->lock);
}

(and sisters)
didn't we have to apply programming note page G4 (G-4 Memory Ordering Model
PA-RISC 2.0 Architecture) with s ==  &rw->lock and x == rw->counter?

Thanks for your patience,
    Joel
