batman-adv: add basic bridge loop avoidance code
This second version of the bridge loop avoidance for batman-adv
avoids loops between the mesh and a backbone (usually a LAN).
By connecting multiple batman-adv mesh nodes to the same ethernet
segment a loop can be created when the soft-interface is bridged
into that ethernet segment. A simple visualization of the loop
involving the most common case - a LAN as ethernet segment:
node1 <-- LAN --> node2
| |
wifi <-- mesh --> wifi
Packets from the LAN (e.g. ARP broadcasts) will circle forever from
node1 or node2 over the mesh back into the LAN.
With this patch, batman recognizes backbone gateways, nodes which are
part of the mesh and backbone/LAN at the same time. Each backbone
gateway "claims" clients from within the mesh to handle them
exclusively. By restricting that only responsible backbone gateways
may handle their claimed clients traffic, loops are effectively
avoided.

Make the "word-at-a-time" helper functions more commonly usable
I have a new optimized x86 "strncpy_from_user()" that will use these
same helper functions for all the same reasons the name lookup code uses
them. This is preparation for that.
This moves them into an architecture-specific header file. It's
architecture-specific for two reasons:
- some of the functions are likely to want architecture-specific
implementations. Even if the current code happens to be "generic" in
the sense that it should work on any little-endian machine, it's
likely that the "multiply by a big constant and shift" implementation
is less than optimal for an architecture that has a guaranteed fast
bit count instruction, for example.
- I expect that if architectures like sparc want to start playing
around with this, we'll need to abstract out a few more details (in
particular the actual unaligned accesses). So we're likely to have
more architecture-specific stuff if non-x86 architectures start using
this.
(and if it turns out that non-x86 architectures don't start using
this, then having it in an architecture-specific header is still the
right thing to do, of course)

9) Add missing address change event emissions to bonding, from Shlomo

10) /proc/net/dev regressed because it uses a private offset to track
where we are in the hash table, but this doesn't track the offset
pullback that the seq_file code does resulting in some entries being
missed in large dumps.
Fix from Eric Dumazet.
11) do_tcp_sendpage() unloads the send queue way too fast, because it
invokes tcp_push() when it shouldn't. Let the natural sequence
generated by the splice paths, and the assosciated MSG_MORE
settings, guide the tcp_push() calls.
Otherwise what goes out of TCP is spaghetti and doesn't batch
effectively into GSO/TSO clusters.
From Eric Dumazet.
12) Once we put a SKB into either the netlink receiver's queue or a
socket error queue, it can be consumed and freed up, therefore we
cannot touch it after queueing it like that.
Fixes from Eric Dumazet.
13) PPP has this annoying behavior in that for every transmit call it
immediately stops the TX queue, then calls down into the next layer
to transmit the PPP frame.
But if that next layer can take it immediately, it just un-stops the
TX queue right before returning from the transmit method.
Besides being useless work, it makes several facilities unusable, in
particular things like the equalizers. Well behaved devices should
only stop the TX queue when they really are full, and in PPP's case
when it gets backlogged to the downstream device.
David Woodhouse therefore fixed PPP to not stop the TX queue until
it's downstream can't take data any more.

tcp: tcp_sendpages() should call tcp_push() once
commit
2f533844242 (tcp: allow splice() to build full TSO packets) added
a regression for splice() calls using SPLICE_F_MORE.
We need to call tcp_flush() at the end of the last page processed in
tcp_sendpages(), or else transmits can be deferred and future sends
stall.
Add a new internal flag, MSG_SENDPAGE_NOTLAST, acting like MSG_MORE, but
with different semantic.
For all sendpage() providers, its a transparent change. Only
sock_sendpage() and tcp_sendpages() can differentiate the two different
flags provided by pipe_to_sendpage()

Merge branch 'akpm' (Andrew's patch-bomb)
Merge batch of fixes from Andrew Morton:
"The simple_open() cleanup was held back while I wanted for laggards to
merge things.
I still need to send a few checkpoint/restore patches. I've been
wobbly about merging them because I'm wobbly about the overall
prospects for success of the project. But after speaking with Pavel
at the LSF conference, it sounds like they're further toward
completion than I feared - apparently davem is at the "has stopped
complaining" stage regarding the net changes. So I need to go back
and re-review those patchs and their (lengthy) discussion."

memcg swap: use mem_cgroup_uncharge_swap fix
Although mem_cgroup_uncharge_swap has an empty placeholder for
!CONFIG_CGROUP_MEM_RES_CTLR_SWAP the definition is placed in the
CONFIG_SWAP ifdef block so we are missing the same definition for
!CONFIG_SWAP which implies !CONFIG_CGROUP_MEM_RES_CTLR_SWAP.
This has not been an issue before, because mem_cgroup_uncharge_swap was
not called from !CONFIG_SWAP context. But Hugh Dickins has a cleanup
patch to call __mem_cgroup_commit_charge_swapin which is defined also
for !CONFIG_SWAP.
Let's move both the empty definition and declaration outside of the
CONFIG_SWAP block to avoid the following compilation error:
mm/memcontrol.c: In function '__mem_cgroup_commit_charge_swapin':
mm/memcontrol.c:2837: error: implicit declaration of function 'mem_cgroup_uncharge_swap'
if CONFIG_SWAP is disabled.

backlight: add driver for DA9052/53 PMIC v1
DA9052/53 PMIC has capability to supply power for upto 3 banks of 6
white serial LEDS. It can also control intensity of independent banks
and to drive these banks boost converter will provide up to 24V and
forward current of max 50mA.
This patch allows to control intensity of the individual WLEDs bank
through DA9052/53 PMIC.
This patch is functionally tested on Samsung SMDKV6410.
