There were a number of bugs that led to the PS2 problems: - a change to __cond_resched() in the -Q series caused the starvation of the IRQ1 and IRQ12 threads during init - causing a silent timeout and misdetection in the ps2 driver(s). - even with the starvation bug fixed, we must set system_state to SCHEDULER_OK only once the init thread has started - otherwise the idle thread might hang during bootup. - the redirected IRQ handling now matches that of non-redirected IRQs better, the outer loop in generic_handle_IRQ has been flattened. i also re-added the synchronize_irq() fix, it was not causing the PS2 problems.
