Pull ARM SoC cleanups from Olof Johansson:
"This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer
API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM
driver and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM
platform code for include changes so we took it through our tree"

TCP receive window handling is multi staged.
A socket has a memory budget, static or dynamic, in sk_rcvbuf.
Because we do not really know how this memory budget translates to
a TCP window (payload), TCP announces a small initial window
(about 20 MSS).
When a packet is received, we increase TCP rcv_win depending
on the payload/truesize ratio of this packet. Good citizen
packets give a hint that it's reasonable to have rcv_win = sk_rcvbuf/2
This heuristic takes place in tcp_grow_window()
Problem is : We currently call tcp_grow_window() only for in-order
packets.
This means that reorders or packet losses stop proper grow of
rcv_win, and senders are unable to benefit from fast recovery,
or proper reordering level detection.
Really, a packet being stored in OFO queue is not a bad citizen.
It should be part of the game as in-order packets.
In our traces, we very often see sender is limited by linux small
receive windows, even if linux hosts use autotuning (DRS) and should
allow rcv_win to grow to ~3MB.

This patch proposes to remove the MLX5_DEBUG kernel configuration
parameter defined in drivers/net/ethernet/mellanox/mlx5/core/Kconfig,
but used nowhere in the makefiles and source code.
This could also be fixed by using this parameter,
but this may be a leftover from driver development...

bnx2x:bnx2x_link_initialize' identified indentation problem, but resolved it
by adding braces instead of fixing the indentation. The braces now prevents a
config_init call in some cases, though it should be called regardless of that
condition. This patch removes the braces and fix the confusing indentation

In commit 0f7cc9a3 "tcp: increase throughput when reordering is high",
it only allows cwnd to increase in Open state. This mistakenly disables
slow start after timeout (CA_Loss). Moreover cwnd won't grow if the
state moves from Disorder to Open later in tcp_fastretrans_alert().
Therefore the correct logic should be to allow cwnd to grow as long
as the data is received in order in Open, Loss, or even Disorder state.

protocols pass, in our case related to networking. If later on, other
subsystems decide they want to add their protocol as well to the list
of allowed protocols they shall simply add it. While at it, we also

The macrology in cmpxchg.h was designed to allow arbitrary pointer
and integer values to be passed through the routines. To support
cmpxchg() on 64-bit values on the 32-bit tilepro architecture, we
used the idiom "(typeof(val))(typeof(val-val))". This way, in the
"size 8" branch of the switch, when the underlying cmpxchg routine
returns a 64-bit quantity, we cast it first to a typeof(val-val)
quantity (i.e. size_t if "val" is a pointer) with no warnings about
casting between pointers and integers of different sizes, then cast
onwards to typeof(val), again with no warnings. If val is not a
pointer type, the additional cast is a no-op. We can't replace the
typeof(val-val) cast with (for example) unsigned long, since then if
"val" is really a 64-bit type, we cast away the high bits.
HOWEVER, this fails with current gcc (through 4.7 at least) if "val"
is a pointer to an incomplete type. Unfortunately gcc isn't smart
enough to realize that "val - val" will always be a size_t type
even if it's an incomplete type pointer.
Accordingly, I've reworked the way we handle the casting. We have
given up the ability to use cmpxchg() on 64-bit values on tilepro,
which is OK in the kernel since we should use cmpxchg64() explicitly
on such values anyway. As a result, I can just use simple "unsigned
long" casts internally.
As I reworked it, I realized it would be cleaner to move the
architecture-specific conditionals for cmpxchg and xchg out of the
atomic.h headers and into cmpxchg, and then use the cmpxchg() and
xchg() primitives directly in atomic.h and elsewhere. This allowed
the cmpxchg.h header to stand on its own without relying on the
implicit include of it that is performed by <asm/atomic.h>.
It also allowed collapsing the atomic_xchg/atomic_cmpxchg routines
from atomic_{32,64}.h into atomic.h.
I improved the tests that guard the allowed size of the arguments
to the routines to use a __compiletime_error() test. (By avoiding
the use of BUILD_BUG, I could include cmpxchg.h into bitops.h as
well and use the macros there, which is otherwise impossible due
to include order dependency issues.)
The tilepro _atomic_xxx internal methods were previously set up to
take atomic_t and atomic64_t arguments, which isn't as convenient
with the new model, so I modified them to take int or u64 arguments,
which is consistent with how they used the arguments internally
anyway, so provided some nice simplification there too.

sw_flow_key alignment was declared as " __aligned(__alignof__(long))".
However, this breaks on the m68k architecture where long is 32 bit in
size but 16 bit aligned by default. This aligns to the size of a long to
ensure that we can always do comparsions in full long-sized chunks. It
also adds an additional build check to catch any reduction in alignment.

Conflicts:
drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c
net/bridge/br_multicast.c
net/ipv6/sit.c
The conflicts were minor:
1) sit.c changes overlap with change to ip_tunnel_xmit() signature.
2) br_multicast.c had an overlap between computing max_delay using
msecs_to_jiffies and turning MLDV2_MRC() into an inline function
with a name using lowercase instead of uppercase letters.
3) stmmac had two overlapping changes, one which conditionally allocated
and hooked up a dma_cfg based upon the presence of the pbl OF property,
and another one handling store-and-forward DMA made. The latter of
which should not go into the new of_find_property() basic block.

This commit fixes a long-standing bug that has been reported by many
users: on some Armada 370 platforms, only the network interface that
has been used in U-Boot to tftp the kernel works properly in
Linux. The other network interfaces can see a 'link up', but are
unable to transmit data. The reports were generally made on the Armada
370-based Mirabox, but have also been given on the Armada 370-RD
board.
The network MAC in the Armada 370/XP (supported by the mvneta driver
in Linux) has a functionality that allows it to continuously poll the
PHY and directly update the MAC configuration accordingly (speed,
duplex, etc.). The very first versions of the driver submitted for
review were using this hardware mechanism, but due to this, the driver
was not integrated with the kernel phylib. Following reviews, the
driver was changed to use the phylib, and therefore a software based
polling. In software based polling, Linux regularly talks to the PHY
over the MDIO bus, and sees if the link status has changed. If it's
the case then the adjust_link() callback of the driver is called to
update the MAC configuration accordingly.
However, it turns out that the adjust_link() callback was not
configuring the hardware in a completely correct way: while it was
setting the speed and duplex bits correctly, it wasn't telling the
hardware to actually take into account those bits rather than what the
hardware-based PHY polling mechanism has concluded. So, in fact the
adjust_link() callback was basically a no-op.
However, the network happened to be working because on the network
interfaces used by U-Boot for tftp on Armada 370 platforms because the
hardware PHY polling was enabled by the bootloader, and left enabled
by Linux. However, the second network interface not used for tftp (or
both network interfaces if the kernel is loaded from USB, NAND or SD
card) didn't had the hardware PHY polling enabled.
This patch fixes this situation by:
(1) Making sure that the hardware PHY polling is disabled by clearing
the MVNETA_PHY_POLLING_ENABLE bit in the MVNETA_UNIT_CONTROL
register in the driver ->probe() function.
(2) Making sure that the duplex and speed selections made by the
adjust_link() callback are taken into account by clearing the
MVNETA_GMAC_AN_SPEED_EN and MVNETA_GMAC_AN_DUPLEX_EN bits in the
MVNETA_GMAC_AUTONEG_CONFIG register.
This patch has been tested on Armada 370 Mirabox, and now both network
interfaces are usable after boot.
