* [BNX2]: Use CPU native page sizeMichael Chan2006-06-172-2/+8
| | | | | | | | | | | | | Use CPU native page size to determine various ring sizes. This allows order-0 memory allocations on all systems. Added check to limit the page size to 16K since that's the maximum rx ring size that will be used. This will prevent using unnecessarily large page sizes on some architectures with large page sizes.

* [NET] ppp: Remove unnecessary pskb_may_pullHerbert Xu2006-06-171-2/+0
| | | | | | | | | | | | In ppp_receive_nonmp_frame, we call pskb_may_pull(skb, skb->len) if the tailroom is >= 124. This is pointless because this pskb_may_pull is only needed if the skb is non-linear. However, if it is non-linear then the tailroom would be zero. So it can be safely removed.

* [NET]: Clean up skb_linearizeHerbert Xu2006-06-173-6/+9
| | | | | | | | | | | | | | | | | | | | | | | The linearisation operation doesn't need to be super-optimised. So we can replace __skb_linearize with __pskb_pull_tail which does the same thing but is more general. Also, most users of skb_linearize end up testing whether the skb is linear or not so it helps to make skb_linearize do just that. Some callers of skb_linearize also use it to copy cloned data, so it's useful to have a new function skb_linearize_cow to copy the data if it's either non-linear or cloned. Last but not least, I've removed the gfp argument since nobody uses it anymore. If it's ever needed we can easily add it back.

* [NET]: Add netif_tx_lockHerbert Xu2006-06-1712-38/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various drivers use xmit_lock internally to synchronise with their transmission routines. They do so without setting xmit_lock_owner. This is fine as long as netpoll is not in use. With netpoll it is possible for deadlocks to occur if xmit_lock_owner isn't set. This is because if a printk occurs while xmit_lock is held and xmit_lock_owner is not set can cause netpoll to attempt to take xmit_lock recursively. While it is possible to resolve this by getting netpoll to use trylock, it is suboptimal because netpoll's sole objective is to maximise the chance of getting the printk out on the wire. So delaying or dropping the message is to be avoided as much as possible. So the only alternative is to always set xmit_lock_owner. The following patch does this by introducing the netif_tx_lock family of functions that take care of setting/unsetting xmit_lock_owner. I renamed xmit_lock to _xmit_lock to indicate that it should not be used directly. I didn't provide irq versions of the netif_tx_lock functions since xmit_lock is meant to be a BH-disabling lock. This is pretty much a straight text substitution except for a small bug fix in winbond. It currently uses netif_stop_queue/spin_unlock_wait to stop transmission. This is unsafe as an IRQ can potentially wake up the queue. So it is safer to use netif_tx_disable. The hamradio bits used spin_lock_irq but it is unnecessary as xmit_lock must never be taken in an IRQ handler. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [TG3]: Add recovery logic when MMIOs are re-orderedMichael Chan2006-06-172-9/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add recovery logic when we suspect that the system is re-ordering MMIOs. Re-ordered MMIOs to the send mailbox can cause bogus tx completions and hit BUG_ON() in the tx completion path. tg3 already has logic to handle re-ordered MMIOs by flushing the MMIOs that must be strictly ordered (such as the send mailbox). Determining when to enable the flush is currently a manual process of adding known chipsets to a list. The new code replaces the BUG_ON() in the tx completion path with the call to tg3_tx_recover(). It will set the TG3_FLAG_MBOX_WRITE_REORDER flag and reset the chip later in the workqueue to recover and start flushing MMIOs to the mailbox. A message to report the problem will be printed. We will then decide whether or not to add the host bridge to the list of chipsets that do re-ordering. We may add some additional code later to print the host bridge's ID so that the user can report it more easily. The assumption that re-ordering can only happen on x86 systems is also removed.

* [PATCH] sky2: netconsole suspend/resume interactionStephen Hemminger2006-06-171-1/+6
| | | | | | | | | | | | | A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

* [PATCH] fix cdrom openJens Axboe2006-06-171-2/+4
| | | | | | | | | | | | | | | | Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

I have managed to reproduce the problem, and the patch below fixes the actual cause. The problem is not in fact in ppp_async.c but in n_tty.c. What happens is that when pptp reads from the pty, we call read_chan() in drivers/char/n_tty.c on the master side of the pty. That copies all the characters out of its buffer to userspace and then calls check_unthrottle(), which calls the pty unthrottle routine, which calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup, which calls tasklet_schedule. So far so good. Since we are in process context, the tasklet runs immediately and calls ppp_async_process(), which calls ppp_async_push, which calls the tty->driver->write function to send some more output. However, tty->driver->write() returns zero, because the master tty->receive_room is still zero. We haven't returned from check_unthrottle() yet, and read_chan() only updates tty->receive_room _after_ calling check_unthrottle. That means that the driver->write call in ppp_async_process() returns 0. That would be fine if we were going to get a subsequent wakeup call, but we aren't (we just had it, and the buffer is now empty). The solution is for n_tty.c to update tty->receive_room _before_ calling the driver unthrottle routine. The patch below does this. With this patch I was able to transfer a 900MB file over a PPTP connection (taking about 25 minutes), whereas without the patch the connection would always stall in under a minute.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was brought to our attention that the prefetches break e1000 traffic on xscale/arm architectures. Remove them for now. We'll let them stay in mm for a while, or find a better solution to enable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New code added in 2.6.17 caused setup_irq to print a warning when running ethtool -t eth0 offline. This test marks the request_irq call made by this test as a "probe" to see if the interrupt is shared or not.
