_ret_from_irq is used by dec/int-handler.S directly, so you should not
remove it (though decstation_defconfig disables CONFIG_PREEMPT).


woah, you're right. the name '_ret_from_irq' looks so private to me
that I didn't think that some other code could use it...

But looking at dec/int-handler.S again, I can not see why it uses
_ret_from_irq, and why it manipulates TI_REGS($28) in handle_it ...

It seems dec/int-handler.S has been broken for a while.  I'll send a
patch to fix it.  If it was ACKed, I ACK your patch.


ok I'm waiting...
