The bug introduced by commit 8c7396aebb68994c0519e438eecdf4d5fa9c7844
("gianfar: Merge Tx and Rx interrupt for scheduling clean up ring").
The commit merged TX and RX interrupt code into a single routine that
schedules NAPI, but no locks were introduced. This causes irq races, so
when irqs are enabled and netif_rx_schedule_prep() returns 0, nobody
disable the interrupts again. This leads to interrupt storm and finally
to the lockup.

Currently htb_do_events() breaks events recounting for a level after 2
jiffies, but there is no reason to repeat this for next levels and
increase delays even more (with softirqs disabled). htb_dequeue_tree()
can add to this too, btw. In such a case q->now time is invalid anyway.
Thanks to Patrick McHardy for spotting an error around earlier version
of this patch.

Next event time should consider jiffies used for recounting. Otherwise
qdisc_watchdog_schedule() triggers hrtimer immediately with the event
in the past, and may cause very high ksoftirqd cpu usage (if highres
is on).
There is also removed checking "event" for zero in htb_dequeue(): it's
always true in this place.

nf_conntrack_alloc cannot return NULL, so there is no need to check for
NULL before using the value. I have also removed the initialization of ct
to NULL in nf_conntrack_alloc, since the value is never used, and since
perhaps it might lead one to think that return ct at the end might return
NULL.
The semantic patch that finds this problem is as follows:

An old bug crept back into the ICMP/ICMPv6 conntrack protocols: the timeout
values are defined as unsigned longs, the sysctl's maxsize is set to
sizeof(unsigned int). Use unsigned int for the timeout values as in the
other conntrack protocols.

The PPPOE/VLAN processing code in the bridge netfilter is broken
by design. The VLAN tag and the PPPOE session ID are an integral
part of the packet flow information, yet they're completely
ignored by the bridge netfilter. This is potentially a security
hole as it treats all VLANs and PPPOE sessions as the same.
What's more, it's actually broken for PPPOE as the bridge netfilter
tries to trim the packets to the IP length without adjusting the
PPPOE header (and adjusting the PPPOE header isn't much better
since the PPPOE peer may require the padding to be present).
Therefore we should disable this by default.
It does mean that people relying on this feature may lose networking
depending on how their bridge netfilter rules are configured.
However, IMHO the problems this code causes are serious enough to
warrant this.

At 37000 feet somewhere near Greenland I woke up from a half-sleep with the
realisation that __lowest_in_progress() is buggy. After landing I checked
and there were indeed 2 problems with it; this patch fixes both:
* The order of the list checks was wrong
* The locking was not correct.

There has been some light flamewar on lkml about decoding oopses
in modules (as part of the crashdump flamewar).
Now this isn't rocket science, just the markup_oops.pl script
cheaped out and didn't handle modules. But really; a flamewar
all about that?? What happened to C++ in the kernel or reading
files from inside the kernel?
This patch adds module support to markup_oops.pl; it's not the
most pretty perl but it works for my testcases...
