This patch fixes a missing _bh in the 23 August locking update. 
Without this any attempt to read from /proc/net/decnet_cache causes a
'scheduling while atomic' crash.

The patch 'RCU: use rcu_assign_pointer()'
http://linux.bkbits.net:8080/linux-2.6/diffs/net/sched/sch_api.c@1.39?nav=index.html|src/net/|src/net|src/net/sched|related/net/sched/sch_api.c|cset@1.2287
changed a list_add_tail to list_add_tail_rcu in qdisc_create. It's
dev->qdisc not dev->qdisc_list that is protected by RCU, this patch
reverts that change. It also removes a misleading comment and replaces
the smp_wmb in qdisc_create_dflt by rcu_assign_pointer in dev_activate
to document more clearly what is protected.

None of the code in __qdisc_destroy should be applied to a builtin qdisc

The patch below prevents builtin qdiscs from being destroyed and
fixes a refcnt underflow whould lead to a bogus list unlinking

We need to open the gap between congestion on/off a little bit, or we
risk burning many cycles continually putting processes on a wait queue
only to wake them up again immediately. This was observed with CFQ at
least, which showed way excessive sys time.

The routine ext2_readdir() will, when reading a directory page
returns an error, try the next page, without reporting the
error to user space. That is bad, and the patch below changes that.

In my case the filesystem was damaged, and ext2_readdir wanted
to read 60000+ pages and wrote as many error messages to syslog
("attempt to access beyond end"), not what one wants.

[no doubt a similar patch is appropriate for ext3]

This preserves 2.4.x behavior.

bits_wanted is expanded to bytes using the wrong shift value
(when iovp_shift != PAGE_SHIFT), resulting in an explosion of
used iommu resources.

This potentially results in mistakenly running out of DMA mapping
resources when the system is under *heavy* i/o load.

Patch from Matthew Wilcox:
  Since some ia64 platforms have non-identity-mapped PCI busses, we need
  to implement pcibios_resource_to_bus and pcibios_bus_to_resource.
  Also clean up some >80 column comments and delete an unnecessary parameter
  to pcibios_fixup_device_resources().

No, this breaks the normal return path.

This patch allows tcpdiag to support ipv6 work as a module when itself
is also a module.

I was planning for a more extensible method but now I think the effort
would be better directed at a new generic socket netlink interface than
the TCP-specific tcpdiag.
