Building brcmfmac for sparc64 gave the following warning:
CC [M] drivers/net/wireless/brcm80211/brcmfmac/bcmsdh_sdmmc.o
bcmsdh_sdmmc.c: In function 'brcmf_sdioh_request_byte':
bcmsdh_sdmmc.c:89:6: warning: 'err_ret' may be used uninitialized
in this function [-Wuninitialized]
Inspecting the code it indeed had a path of execution in
which the return value was used uninitialized. This patch
fixes that code path.

When building randconfigs with CONFIG_BCMA_DRIVER_GPIO=y, I get

drivers/built-in.o: In function `brcms_led_register':

during final linking stage because brcmsmac/led.c needs LEDS_CLASS for
registering/deregistering the led device. Select the required symbols.

Use this new function to make code more comprehensible, since we are

If the SDIO host controller does not support scatter-gather the glom
superframe must be transfered from the device and the data for each

Just some minor conflicts between the wireless-next changes
and Joe Perches's "extern" removal from function prototypes
in header files.
John W. Linville says:
====================
Regarding the Bluetooth bits, Gustavo says:
"The big work here is from Marcel and Johan. They did a lot of work
in the L2CAP, HCI and MGMT layers. The most important ones are the
addition of a new MGMT command to enable/disable LE advertisement
and the introduction of the HCI user channel to allow applications
to get directly and exclusive access to Bluetooth devices."
As to the ath10k bits, Kalle says:
"Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's
just too much to support it. Michal added support for the new firmware
interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are
minor fixes or cleanups."
And also:
"Major changes are:
* throughput improvements including aligning the RX frames correctly and
optimising HTT layer (Michal)
* remove qca98xx hw1.0 support (Bartosz)
* add support for firmware version 999.999.0.636 (Michal)
* firmware htt statistics support (Kalle)
* fix WEP in AP and IBSS mode (Marek)
* fix a mutex unlock balance in debugfs file (Shafi)
And of course there's a lot of smaller fixes and cleanup."
For the wl12xx bits, Luca says:
"Here are some patches intended for 3.13. Eliad is upstreaming a bunch
of patches that have been pending in the internal tree. Mostly bugfixes
and other small improvements."
Along with that...
Arend and friends bring us a batch of brcmfmac updates, Larry Finger
offers some rtlwifi refactoring, and Sujith sends the usual batch of
ath9k updates. As usual, there are a number of other small updates
from a variety of players as well.

The definition of BRCMF_EVENTING_MASK_LEN results in a sparse

.../fweh.c:331:22: error: bad constant expression
.../fweh.c:388:22: error: bad constant expression
.../dhd_common.c:256:22: error: bad constant expression
This is caused by the use of roundup() in BRCMF_EVENTING_MASK_LEN
and it is used to allocate an array variable on the stack. Better
use DIV_ROUND_UP() macro.

The driver uses platform_driver_probe() to obtain platform data
if any. However, that function is placed in the .init section so
it must be called upon driver module initialization.
The problem was reported by Fenguang Wu resulting in a kernel
oops because the .init section was already freed.

There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

The kernel configuration for the driver could result in
compilation issues as reported by Randy Dunlap. His results
are show below:
"on x86_64:
when
CONFIG_MMC=m
CONFIG_BRCMUTIL=y
CONFIG_BRCMFMAC=y
CONFIG_BRCMFMAC_SDIO=y
This bool kconfig symbol:
config BRCMFMAC_SDIO
bool "SDIO bus interface support for FullMAC driver"
depends on MMC
allows BRCMFMAC_SDIO to be y even when MMC=m.
Is there a reasonable solution to this?
This causes many build errors:
drivers/built-in.o: In function `brcmf_sdio_assert_info':
dhd_sdio.c:(.text+0x39609b): undefined reference to `sdio_claim_host'
dhd_sdio.c:(.text+0x3960d9): undefined reference to `sdio_release_host'
drivers/built-in.o: In function `brcmf_sdio_readframes':
dhd_sdio.c:(.text+0x396a62): undefined reference to `sdio_claim_host'
dhd_sdio.c:(.text+0x396a9b): undefined reference to `sdio_release_host'
..."
This patch adds the appropriate logic in Kconfig to resolve
these issues. The solution was provided by Hauke Mehrtens.

Pull networking changes from David Miller:
"Noteworthy changes this time around:
1) Multicast rejoin support for team driver, from Jiri Pirko.
2) Centralize and simplify TCP RTT measurement handling in order to
reduce the impact of bad RTO seeding from SYN/ACKs. Also, when
both timestamps and local RTT measurements are available prefer
the later because there are broken middleware devices which
scramble the timestamp.
From Yuchung Cheng.
3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel
memory consumed to queue up unsend user data. From Eric Dumazet.
4) Add a "physical port ID" abstraction for network devices, from
Jiri Pirko.
5) Add a "suppress" operation to influence fib_rules lookups, from
Stefan Tomanek.
6) Add a networking development FAQ, from Paul Gortmaker.
7) Extend the information provided by tcp_probe and add ipv6 support,
from Daniel Borkmann.
8) Use RCU locking more extensively in openvswitch data paths, from
Pravin B Shelar.
9) Add SCTP support to openvswitch, from Joe Stringer.
10) Add EF10 chip support to SFC driver, from Ben Hutchings.
11) Add new SYNPROXY netfilter target, from Patrick McHardy.
12) Compute a rate approximation for sending in TCP sockets, and use
this to more intelligently coalesce TSO frames. Furthermore, add
a new packet scheduler which takes advantage of this estimate when
available. From Eric Dumazet.
13) Allow AF_PACKET fanouts with random selection, from Daniel
Borkmann.
14) Add ipv6 support to vxlan driver, from Cong Wang"

up with PTR_ERR_OR_ZERO(), and replacing or fixing all the usages.
This has been sitting in linux-next for a whole cycle"

possibly being new, but most of them existing in Rusty's tree too. We
have that
