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'.

This patch fixes a regression introduced by:
commit 6da3b6c48d79da96a36c2632053cf4f53bf48fb2
Author: Hauke Mehrtens <hauke@hauke-m.de>

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.

The firmware is requested from user-space. To assure the request
is handled it is recommended to do the request upon IFF_UP. For
a mac80211 driver the .start() callback can be considered the
equivalent.

It is possible to configure the ucode to automatically send the probe
responses to the clients after they send a probe request. At least for
WPS the userspace needs to answer the probe requests and we do not know
a way to say to the ucode to just handle the normal probe requests, so
for now no probe requests should be handled by the ucode.

This patch addresses a long standing issue of the driver with the
mac80211 .flush() callback. Since implementing the .flush() callback
a number of issues have been fixed, but a WARN_ON_ONCE() was still
triggered because the timeout on the flush could still occur.
This patch changes the awkward design using msleep() into one using
a waitqueue. The waiting flush() context will kick the transmit dma
when it is idle and the timeout used waiting for the event is set
to 500 ms. Worst case there can be 64 frames outstanding for transmit
in the driver. At a rate of 1Mbps that would take 1.5 seconds assuming
MTU is 1500 bytes and ignoring retries. The WARN_ON_ONCE() is also
removed as this was put in to indicate the flush timeout as a reason
for the driver to stall. That was not happening since fixing endless
AMPDU retries with following upstream commit:

This issue was reported on the wireless list (see [1]) in which
brcmsmac ran into a fatal error:
[ 588.284074] brcmsmac bcma0:0: frameid != txh->TxFrameID
[ 588.284098] brcmsmac bcma0:0: MI_TFS: fatal
[ 588.284103] brcmsmac bcma0:0: wl0: fatal error, reinitializing
[ 588.286208] ieee80211 phy0: Hardware restart was requested
The tx status feedback is processed in a loop limiting the number of
frames processed in one run. The code terminate processing when the
limit is reached regardless the txstatus value read from the device
register. When that status is is flagged as being valid it must be
processed as the hardware will clear it after is has been read.
Bisecting was done by Seth Forshee and showed following commit as the
culprit:

Depending on the driver, having ARP filtering for
some addresses may be possible. Remove the logic
that tracks whether ARP filter is enabled or not
and give the driver the total number of addresses
instead of the length of the list so it can make
