b67bfe0d42 hlist: drop the node parameter from iterators
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:

On unload, b43 produces a lockdep warning that can be summarized in the

 ======================================================
 [ INFO: possible circular locking dependency detected ]
 3.8.0-wl+ #117 Not tainted
 -------------------------------------------------------
 modprobe/5557 is trying to acquire lock:
  ((&wl->firmware_load)){+.+.+.}, at: [<ffffffff81062160>] flush_work+0x0/0x2a0

 but task is already holding lock:

 [ INFO: possible circular locking dependency detected ]
 ======================================================

The full output is available at http://lkml.indiana.edu/hypermail/linux/kernel/1302.3/00060.html.
To summarize, commit 6b6fa58 added a 'cancel_work_sync(&wl->firmware_load)'
call in the wrong place.

The fix is to move the cancel_work_sync() call to b43_bcma_remove() and
b43_ssb_remove(). Thanks to Johannes Berg and Michael Buesch for help in
diagnosing the log output.

48412a7e7d vmxnet3: fix ethtool ring buffer size setting
Noticed that vmxnet3's get_ringparam function was returning the summation of all
ring buffers on a NIC, rather than just the size of any one ring.  This causes
problems when a vmxnet3 instance has multiple queues, as ethtool, when setting
ring parameters, first gets the current ring parameters to set the existing
values in the set_ringparm commannd.  The result is, that unless both rx and tx
ring sizes are set in a single operation, which ever ring is not set will
silently have its ring count multiplied by the number of queues on the NIC until
it reaches a driver defined maxiumum value.

Fix it by not multiplying the rx and tx ring sizes by the number of queues in
the system, like every other driver.  Tested by myself successfully.

732ac8cacb bnx2x: remove dead code and make local funcs static
Sparse warned about several functions that were unnecessarily global.
After making them static, discovered that several functions were actually never used.

62ed839dba gianfar: fix compile fail for NET_POLL=y due to struct packing
Commit ee873fda3b ("gianfar: Pack struct
gfar_priv_grp into three cachelines") moved the irq number and names
off into a separate struct and created accessors for them.  However
it was never tested with NET_POLL enabled, and so some conversions
that were simply overlooked went undetected until now.

Make the netpoll ones also use the gfar_irq() accessors.

Pull powerpc updates from Benjamin Herrenschmidt:
 "So from the depth of frozen Minnesota, here's the powerpc pull request
  for 3.9.  It has a few interesting highlights, in addition to the
  usual bunch of bug fixes, minor updates, embedded device tree updates
  and new boards:

   - Hand tuned asm implementation of SHA1 (by Paulus & Michael
     Ellerman)

   - Support for Doorbell interrupts on Power8 (kind of fast
     thread-thread IPIs) by Ian Munsie

   - Long overdue cleanup of the way we handle relocation of our open
     firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard

   - Support for saving/restoring & context switching the PPR (Processor
     Priority Register) on server processors that support it.  This
     allows the kernel to preserve thread priorities established by
     userspace.  By Haren Myneni.

   - DAWR (new watchpoint facility) support on Power8 by Michael Neuling

   - Ability to change the DSCR (Data Stream Control Register) which
     controls cache prefetching on a running process via ptrace by
     Alexey Kardashevskiy

   - Support for context switching the TAR register on Power8 (new
     branch target register meant to be used by some new specific
     userspace perf event interrupt facility which is yet to be enabled)
     by Ian Munsie.

   - Improve preservation of the CFAR register (which captures the
     origin of a branch) on various exception conditions by Paulus.

   - Move the Bestcomm DMA driver from arch powerpc to drivers/dma where
     it belongs by Philippe De Muyter

   - Support for Transactional Memory on Power8 by Michael Neuling
     (based on original work by Matt Evans).  For those curious about
     the feature, the patch contains a pretty good description."

3770699675 mlx4_en: fix allocation of CPU affinity reverse-map
The mlx4_en driver allocates the number of objects for the CPU affinity
reverse-map based on the number of rx rings of the device. However,
mlx4_assign_eq() calls irq_cpu_rmap_add() as many times as IRQ's are
assigned to EQ's, which can be as large as mlx4_dev->caps.comp_pool. If
caps.comp_pool is larger than rx_ring_num we will eventually hit the
BUG_ON() in cpu_rmap_add().

Fix this problem by allocating space for the maximum number of CPU
affinity reverse-map objects we might want to add.

commit 7f7d6c282 (net: fec: Ensure that initialization is done prior to

48f4d91679 mwifiex: fix system freeze while reloading driver
Unload sequence for mwifiex PCIE driver is as follows:
1. Invoking cleanup module from kernel results into
   pci_unregister_driver
2. Kernel invokes PCIE remove() handler which disconnects all
   interfaces.
3. One step during disconnect is to clean PCIE TX rings.
   During this we read txbd_rdptr from FW.

While loading driver next time, we see pci_enable_device()
results into system freeze. This may have happened because we
accessed PCI device after unregistering from bus driver.
Removing this ioread() operation resolves this bug.

If the system suspends with mwifiex wifi powered on, and is then woken
by an ICMP ping packet, the ping response is discarded by the kernel
because the kernel incorrectly thinks there is no carrier.

I can't see any valid reason to want to report loss of carrier here,
so remove the offending code.

3298a3511f arm-soc: multiplatform support
Converting more ARM platforms to multiplatform support. This time, OMAP
 gets converted, which is a major step since this is by far the largest
 platform in terms of code size. The same thing happens to the vt8500
 platform.
 
 Conflicts include:
 * Two mach/uncompress.h files are removed, the changes made to them
   elsewhere can be discarded now.
 * Moving the OMAP4 irq_match array has context clashes with turning
   omap4_sar_ram_init into an omap_early_initcall()

06991c28f3 Driver core patches for 3.9-rc1
Here is the big driver core merge for 3.9-rc1
 
 There are two major series here, both of which touch lots of drivers all
 over the kernel, and will cause you some merge conflicts:
   - add a new function called devm_ioremap_resource() to properly be
     able to check return values.
   - remove CONFIG_EXPERIMENTAL
 
 If you need me to provide a merged tree to handle these resolutions,
 please let me know.
 
 Other than those patches, there's not much here, some minor fixes and

Pull networking update from David Miller:

 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
    timestamp offset.  From Andrey Vagin.

 2) VMWARE VM VSOCK layer, from Andy King.

 3) Much improved support for virtual functions and SR-IOV in bnx2x,
    from Ariel ELior.

 4) All protocols on ipv4 and ipv6 are now network namespace aware, and
    all the compatability checks for initial-namespace-only protocols is
    removed.  Thanks to Tom Parkin for helping deal with the last major
    holdout, L2TP.

 5) IPV6 support in netpoll and network namespace support in pktgen,
    from Cong Wang.

 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
    Protocol (MVRP) support, from David Ward.

 7) Compute packet lengths more accurately in the packet scheduler, from
    Eric Dumazet.

 8) Use per-task page fragment allocator in skb_append_datato_frags(),
    also from Eric Dumazet.

 9) Add support for connection tracking labels in netfilter, from
    Florian Westphal.

10) Fix default multicast group joining on ipv6, and add anti-spoofing
    checks to 6to4 and 6rd.  From Hannes Frederic Sowa.

11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
    times, rearrange inet frag datastructures for better cacheline
    locality, and move more operations outside of locking.  From Jesper
    Dangaard Brouer.

12) Instead of strict master <--> slave relationships, allow arbitrary
    scenerios with "upper device lists".  From Jiri Pirko.

13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
    Pirko.

14) Add a BPF filter netfilter match target, from Willem de Bruijn.

15) Orphan and delete a bunch of pre-historic networking drivers from
    Paul Gortmaker.

16) Add TSO support for GRE tunnels, from Pravin B SHelar.  Although
    this still needs some minor bug fixing before it's %100 correct in
    all cases.

17) Handle unresolved IPSEC states like ARP, with a resolution packet
    queue.  From Steffen Klassert.

18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
    Hemminger.  This was long overdue.

19) Support SO_REUSEPORT, from Tom Herbert.

20) Allow locking a socket BPF filter, so that it cannot change after a
    process drops capabilities.

21) Add VLAN filtering to bridge, from Vlad Yasevich.

22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in
    the ipv6 routes, from YOSHIFUJI Hideaki.

 - include DT alias names in device uevent
 - Selftest bugfixes and improvements
 - New function for counting phandles stanzas in a property
 - constify argument to of_node_full_name()

Pull workqueue [delayed_]work_pending() cleanups from Tejun Heo:
 "This is part of on-going cleanups to remove / minimize usages of
  workqueue interfaces which are deprecated and/or misleading.

  This round drops a number of usages of [delayed_]work_pending(), which
  are dangerous as they lack any form of synchronization and thus often
  lead to buggy / unnecessary code.  There are a couple legitimate use
  cases in kernel.  Hopefully, they can be converted and
  [delayed_]work_pending() can be removed completely.  Even if not,
  removing most of misuses should make it more difficult to find
  examples of misuses and thus slow down growth of them.
