Pull networking fixes from David Miller:
"Several networking final fixes and tidies for the merge window:
1) Changes during the merge window unintentionally took away the
ability to build bluetooth modular, fix from Geert Uytterhoeven.
2) Several phy_node reference count bug fixes from Uwe Kleine-König.
3) Fix ucc_geth build failures, also from Uwe Kleine-König.
4) Fix klog false positivies when netlink messages go to network
taps, by properly resetting the network header. Fix from Daniel
Borkmann.
5) Sizing estimate of VF netlink messages is too small, from Jiri
Benc.
6) New APM X-Gene SoC ethernet driver, from Iyappan Subramanian.
7) VLAN untagging is erroneously dependent upon whether the VLAN
module is loaded or not, but there are generic dependencies that
matter wrt what can be expected as the SKB enters the stack.
Make the basic untagging generic code, and do it unconditionally.
From Vlad Yasevich.
8) xen-netfront only has so many slots in it's transmit queue so
linearize packets that have too many frags. From Zoltan Kiss.
9) Fix suspend/resume PHY handling in bcmgenet driver, from Florian
Fainelli"

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.
The semantic patch which is mostly the work of Peter Senna Tschudin is here:

We have conflicting type qualifiers for "freg_t" in s390's ptrace.h and the
iphase atm device driver, which causes the compile error below.
Unfortunately the s390 typedef can't be renamed, since it's a user visible api,
nor can I change the include order in s390 code to avoid the conflict.
So simply rename the iphase typedef to a new name. Fixes this compile error:

- Clear ATM_VF_ADDR only when the PKT_PCLOSE packet has been submitted.
- Don't clear ATM_VF_READY at all — vcc_destroy_socket() does that for us.

We should no longer be calling the old pop routine for the vcc, after
vcc_release() has completed. Make sure we wait for any pending TX skbs
to complete, by waiting for our own PKT_PCLOSE control skb to be sent.

Convert a 0 error return code to a negative one, as returned elsewhere in the

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>

@@
(

)
... when != ret = e1
*x = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\|ioremap\|ioremap_nocache\|devm_ioremap\|devm_ioremap_nocache\)(...);
... when != x = e2
when != ret = e3
*if (x == NULL || ...)
{
... when != ret = e4

DMA support has finally made its way to the top of the TODO list, having
realised that a Geode using MMIO can't keep up with two ADSL2+ lines
each running at 21Mb/s.
This patch fixes a couple of bugs in the DMA support in the driver, so
once the corresponding FPGA update is complete and tested everything
should work properly.
We weren't storing the currently-transmitting skb, so we were never
unmapping it and never freeing/popping it when the TX was done.
And the addition of pci_set_master() is fairly self-explanatory.

With the recent changes for how we compute the skb truesize it occurs to me
we are probably going to have a lot of calls to skb_end_pointer -
skb->head. Instead of running all over the place doing that it would make
more sense to just make it a separate inline skb_end_offset(skb) that way
we can return the correct value without having gcc having to do all the
optimization to cancel out skb->head - skb->head.

'break' is unnecessary after 'return' statement.
Remove all such 'break' as clean up.
