Didn't change anything manually in that function, only the wireless26 patch
from you and setting the BADNESS_LIMIT define to 0.
static void bcm43xx_periodic_work_handler(void *d)
{
struct bcm43xx_private *bcm = d;
unsigned long flags;
u32 savedirqs = 0;
int badness;
mutex_lock(&bcm->mutex);
badness = estimate_periodic_work_badness(bcm->periodic_state);
if (badness > BADNESS_LIMIT) {
/* Periodic work will take a long time, so we want it to
* be preemtible.
*/
netif_tx_disable(bcm->net_dev);
spin_lock_irqsave(&bcm->irq_lock, flags);
bcm43xx_mac_suspend(bcm);
if (bcm43xx_using_pio(bcm))
bcm43xx_pio_freeze_txqueues(bcm);
savedirqs = bcm43xx_interrupt_disable(bcm, BCM43xx_IRQ_ALL);
spin_unlock_irqrestore(&bcm->irq_lock, flags);
bcm43xx_synchronize_irq(bcm);
} else {
/* Periodic work should take short time, so we want low
* locking overhead.
*/
spin_lock_irqsave(&bcm->irq_lock, flags);
}
do_periodic_work(bcm);
if (badness > BADNESS_LIMIT) {
spin_lock_irqsave(&bcm->irq_lock, flags);
tasklet_enable(&bcm->isr_tasklet);
bcm43xx_interrupt_enable(bcm, savedirqs);
if (bcm43xx_using_pio(bcm))
bcm43xx_pio_thaw_txqueues(bcm);
bcm43xx_mac_enable(bcm);
netif_wake_queue(bcm->net_dev);
}
mmiowb();
spin_unlock_irqrestore(&bcm->irq_lock, flags);
mutex_unlock(&bcm->mutex);
}
