The only R8A7740 specific #ifdef hindering ARM multiplatform build is left in
sh_eth_rx(): it covers the code shifting Rx buffer descriptor word 0 by 16. Get
rid of the #ifdef by adding 'shift_rd0' field to the 'struct sh_eth_cpu_data',
making the shift dependent on it, and setting it to 1 for the R8A7740 case...

net/batman-adv/bat_iv_ogm.c
net/wireless/nl80211.c
The ath9k Kconfig conflict was a change of a Kconfig option name right
next to the deletion of another option.
The xen-netback conflict was overlapping changes involving the
handling of the notify list in xen_netbk_rx_action().
Batman conflict resolution provided by Antonio Quartulli, basically
keep everything in both conflict hunks.
The nl80211 conflict is a little more involved. In 'net' we added a
dynamic memory allocation to nl80211_dump_wiphy() to fix a race that
Linus reported. Meanwhile in 'net-next' the handlers were converted
to use pre and post doit handlers which use a flag to determine
whether to hold the RTNL mutex around the operation.
However, the dump handlers to not use this logic. Instead they have
to explicitly do the locking. There were apparent bugs in the
conversion of nl80211_dump_wiphy() in that we were not dropping the
RTNL mutex in all the return paths, and it seems we very much should
be doing so. So I fixed that whilst handling the overlapping changes.
To simplify the initial returns, I take the RTNL mutex after we try
to allocate 'tb'.

vxlan: only migrate dynamic FDB entries
was not correct because it is checking flag about type of FDB
entry, rather than the state (dynamic versus static). The confusion
arises because vxlan is reusing values from bridge, and bridge is
reusing values from neighbour table, and easy to get lost in translation.

The usb_8dev hardware has problems on some xhci USB hosts. The driver fails to

The change set of 4305b541, "[SK_BUFF]: Convert skb->end to sk_buff_data_t"
converted skb->end from pointer type to sk_buff_data_t.
The pointed value should be accessed via skb_end_pointer().
Since arm arch doesn't define NET_SKBUFF_DATA_USES_OFFSET,
skb->end is effectively pointer. So it doesn't cause a real problem.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless
John W. Linville says:
====================
This will probably be the last batch of wireless fixes intended
for 3.10. Many of these are one- or two-liners, and a couple of
others are mostly relocating existing code to avoid races or to
limit the code to effecting specific hardware, etc.
The mac80211 fixes have a couple of exceptions to the above.
Regarding those, Johannes says:
"Following davem's complaint about my patch, here's a new pull request
w/o the patch he was complaining about, but instead with the const
fix rolled into the fix.
I have a fix for radar detection, one for rate control and a workaround
for broken HT APs which is a regression fix because we didn't rely
on them to be correct before."
Johannes also sends some iwlwifi fixes:
"I picked up Nikolay's patch for the chain noise calibration bug
that seems to have been there forever, a fix from Emmanuel for
setting TX flags on BAR frames and a fix of my own to avoid printing
request_module() errors if the kernel isn't even modular. We also
have our own version of Stanislaw's fix for rate control."
Along with those...
Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU
value is set to too small of a value.
Arend van Spriel sends a revised brcmsmac bug that fixes a regression
caused by a bad return value in an earlier patch. He also sends a
brcmfmac fix to avoid an oops when loading the driver at boot.
Daniel Drake fixes a race condition in btmrvl that causes hangs on
suspend for OLPC hardware.
Johan Hedberg adds a check to avoid sending a
HCI_Delete_Stored_Link_Key command to devices that don't support them,
avoiding some scary looking log spam.
Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates
higher than 1Mb/s on older wireless networks. He also sends an rt2x00
fix to reinstate older tx power handling behavior for some devices
that didn't work well with the current code.

This is a very simple driver, based on the original vendor
driver that Qualcomm/Atheros published/submitted previously,
but reworked to make the code saner. However, it also lost
a number of features (TSO/GSO, VLAN acceleration and multi-
queue support) in the process, as well as debugging support
features I didn't have any use for. The only thing I left
is checksum offload.
More features can obviously be added, but this seemed like
a good start for having a driver in mainline at all.
Johannes Stezenbach has verified that the driver works on
AR8161, I have a AR8171 myself. The E2200 device ID I found
on github in somebody's repository.

The current tg3 code assumes the pci_error_handlers to be always called
in sequence. In particular, during ->error_detected(), NAPI is disabled
and the device is shutdown. The device is later reset and NAPI
re-enabled in ->slot_reset() and ->resume().
In EEH, if more than 6 errors are detected in a hour, only
->error_detected() will be called. This will leave the driver in an
inconsistent state as NAPI is disabled but netif_running state is still
true. When the device is later closed, we'll try to disable NAPI again
and it will loop forever.
We fix this by closing the device if we encounter any error conditions
during the normal sequence of the pci_error_handlers.
v2: Remove the changes in tg3_io_resume() based on Benjamin Poirier's
feedback.

This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345
has a slightly different and older DMA engine which requires the
following modifications:
- the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes,
which means that the helpers enet_dma{c,s} need to account for this
channel width and we can no longer use macros
- BCM6345 DMA engine does not have any internal SRAM for transfering
buffers
- BCM6345 buffer allocation and flow control is not per-channel but
global (done in RSET_ENETDMA)
- the DMA engine bits are right-shifted by 3 compared to other DMA
generations
- the DMA enable/interrupt masks are a little different (we need to
enabled more bits for 6345)
- some register have the same meaning but are offsetted in the ENET_DMAC
space so a lookup table is required to return the proper offset
The MAC itself is identical and requires no modifications to work.

Some systems that don't need wake-on-lan may choose to power down the
chip on system standby. Upon resume, the power on causes the boot code
to startup and initialize the hardware. On one new platform, this is
causing the device to go into a bad state due to a race between the
driver and boot code, once every several hundred resumes. The same race
exists on open since we come up from a power on.
This patch adds a wait for boot code signature at the beginning of
tg3_init_hw() which is common to both cases. If there has not been a
power-off or the boot code has already completed, the signature will be
present and poll_fw() returns immediately. Also return immediately if
the device does not have firmware.

First the type of igmp_retrans (which is the actual counter of
igmp_resend parameter) is changed to u8 to be able to store values up
to 255 (as per documentation). There are two races that were hidden
there and which are easy to trigger after the previous fix, the first is
between bond_resend_igmp_join_requests and bond_change_active_slave
where igmp_retrans is set and can be altered by the periodic. The second
race condition is between multiple running instances of the periodic
(upon execution it can be scheduled again for immediate execution which
can cause the counter to go < 0 which in the unsigned case leads to
unnecessary igmp retransmissions).
Since in bond_change_active_slave bond->lock is held for reading and
curr_slave_lock for writing, we use curr_slave_lock for mutual
exclusion. We can't drop them as there're cases where RTNL is not held
when bond_change_active_slave is called. RCU is unlocked in
bond_resend_igmp_join_requests before getting curr_slave_lock since we
don't need it there and it's pointless to delay.
The decrement is moved inside the "if" block because if we decrement
unconditionally there's still a possibility for a race condition although
it is much more difficult to hit (many changes have to happen in
a very short period in order to trigger) which in the case of 3 parallel
running instances of this function and igmp_retrans == 1
(with check bond->igmp_retrans-- > 1) is:
f1 passes, doesn't re-schedule, but decrements - igmp_retrans = 0
f2 then passes, doesn't re-schedule, but decrements - igmp_retrans = 255
f3 does the unnecessary retransmissions.

If the bond device is supposed to get the first slave's MAC address and
the first enslavement fails then we need to reset the master's MAC
otherwise it will stay the same as the failed slave device. We do it
after err_undo_flags since that is the first place where the MAC can be
changed and we check if it should've been the first slave and if the
bond's MAC was set to it because that err place is used by multiple
locations prior to changing the master's MAC address.

commit df8ef8f3aaa6692970a436204c4429210addb23a
"macvlan: add FDB bridge ops and macvlan flags"
added a way to control NOPROMISC macvlan flag through netlink.
However, with a non passthrough device we never set promisc on open,
even if NOPROMISC is off. As a result:
If userspace clears NOPROMISC on open, then does not clear it on a
netlink command, promisc counter is not decremented on stop and there
will be no way to clear it once macvlan is detached.
If userspace does not clear NOPROMISC on open, then sets NOPROMISC on a
netlink command, promisc counter will be decremented from 0 and overflow
to fffffffff with no way to clear promisc.
To fix, simply ignore NOPROMISC flag in a netlink command for
non-passthrough devices, same as we do at open/close.
Since we touch this code anyway - check dev_set_promiscuity return code
and pass it to users (though an error here is unlikely).

over the initial cut. No doubt there will be more changes ahead,
but I think it is looking alright at this point.
Along with that, there is the usual flurry of updates to the mac80211
core and the iwlwifi, mwifiex, ath9k, rt2x00, wil6210, and other
drivers. A few of the highlights are some rt2x00 refactoring/cleanup
by Gabor Juhos, some rt2800 hardware support enhancements by Stanislaw
Gruszka, some iwlwifi power management updates from Alexander Bondar,
some enhanced bcma SPROM support from Rafał Miłecki, and a variety
of other things here and there.

Commit 9f86134155047720a3685cda21467f68695152d2 (sh_eth: remove SH_ETH_HAS_TSU)
removes 'const' from 'sh_eth_netdev_ops' and modifies it in case TSU registers
are present. I've originally suggested to Iwamatsu-san to split this structure
in two instead and afterwards Dave M. suggested doing the same.
Split 'sh_eth_netdev_ops_tsu' from 'sh_eth_netdev_ops', making both 'const', and
assigning 'ndev->detdev_ops' depending on the presence of TSU registers.

My change:
commit cee2c7315f60beeff6137ee59e99acc77d636eeb
Author: Stanislaw Gruszka <sgruszka@redhat.com>
Date: Fri Oct 5 13:44:09 2012 +0200
rt2800: use BBP_R1 for setting tx power
unfortunately does not work well with RT5390 and RT3290 chips as they
require different temperature compensation TX power settings (TSSI
tuning). Since that commit make wireless connection very unstable on
those chips, restore previous behavior to fix regression. Once we
implement proper TSSI tuning on 5390/3290 we can restore back setting
TX power by BBP_R1 register for those chips.

This patch fixes a regression introduced by:
commit 6da3b6c48d79da96a36c2632053cf4f53bf48fb2
Author: Hauke Mehrtens <hauke@hauke-m.de>
Date: Sun Mar 24 01:45:52 2013 +0100
brcmsmac: remove brcms_bss_cfg->associated
The regression behaviour was described on mailing list.
http://mid.gmane.org/5197DC4F.7030503@broadcom.com:
"On laptop I installed kernel with brcmsmac compiled as
module. It comes up and associates during boot, but after
logging in there is no connectivity. Triggering reassoc
gives connectivity for some time, but after a while (1-2 min)
it stops."
Before the mentioned commit the return value of
the function brcms_c_ps_allowed() was always false,
which is desired behaviour as power-save is not
supported at the moment. Therefor, the function is
changed to just return false instead of simply
reverting the mentioned commit.

Since driver does not use control.rates[0].count, we have never set that
variable. But currently, after rate control API rewrite, this is required
by mac80211. Otherwise legacy rates control does not work and we transmit
always at 1Mbit/s on pre 11n networks.
