When using nanosleep() in an userspace application we get a
ratelimit warning

NOHZ: local_softirq_pending 08

for 10 times.

This patch replaces netif_rx() with netif_rx_ni() which has
to be used from process/softirq context.
The process/softirq context will be called from fakelb driver.

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem

Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC.
Both uses common Atheros code from ath.ko and need ATH_COMMON.

However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not.
As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with
unresolved symbols.

This patch moves ATH_COMMON selection to the common part for both
ATH9K and ATH9K_HTC

Commit 63233159:
    bridge: Do not unregister all PF_BRIDGE rtnl operations
introduced a bug where a removal of a single bridge from a
multi-bridge system would remove MDB netlink handlers.
The handlers should only be removed once all bridges are gone, but
since we don't keep track of the number of bridge interfaces, it's
simpler to do it when the bridge module is unloaded.  To make it
consistent, move the registration code into module initialization
code path.

wlc_lcnphy_rx_iq_cal_gain is called during initialization, i. e. when

But brcms_up is called from brcms_ops_start while the latter holds a spin lock.
Thus, we cannot use usleep_range but have to use udelay.

Sean reported that as of 3.7, his AR9170 device no longer works
because the driver fails during initialization. He noted this
is due to:
"In carl9170/fw.c, ar->hw->wiphy is tagged with
NL80211_IFTYPE_MESH_POINT support if the firmware has Content
after Beacon Queuing. This is both in interface_modes and the
only iface_combinations entry.

If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw
removes NL80211_IFTYPE_MESH_POINT from interface_modes, but
not iface_combinations.

wiphy_register then checks to see if every interface type in
every interface combination is in interface_modes.
NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON
warning and it returns -EINVAL, giving up."

Unfortunately, the iface_combination (types) feature bitmap
in ieee80211_iface_limit is part of a const member in the
ieee80211_iface_combination struct. Hence, the MESH_POINT
feature flag can't be masked by wiphy_register in the
same way as interface_modes in ieee80211_register_hw.

====================
The following batch contains Netfilter fixes for 3.8-rc1. They are

stable) and more fresh ones from the previous merge window, they are:

* Fix for MAC address in 6in4 tunnels via NFLOG that results in ulogd
  showing up wrong address, from Bob Hockney.

* Fix a comment in nf_conntrack_ipv6, from Florent Fourcot.

* Fix a leak an error path in ctnetlink while creating an expectation,

* Fix missing ICMP time exceeded in the IPv6 defragmentation code, from

* Fix inconsistent handling of routing changes in MASQUERADE for the

* Fix a missing skb_reset_transport in ip[6]t_REJECT that leads to
  crashes in the ixgbe driver (since it seems to access the transport
  header with TSO enabled), from Mukund Jampala.

* Recover obsoleted NOTRACK target by including it into the CT and spot
  a warning via printk about being obsoleted. Many people don't check the
  scheduled to be removal file under Documentation, so we follow some
  less agressive approach to kill this in a year or so. Spotted by Florian
  Westphal, patch from myself.

* Fix race condition in xt_hashlimit that allows to create two or more
  entries, from myself.

* Fix crash if the CT is used due to the recently added facilities to
  consult the dying and unconfirmed conntrack lists, from myself.

In commit 96e0bf4b (tcp: Discard segments that ack data not yet
sent) John Dykstra enforced a check against ack sequences.

In commit 354e4aa3 (tcp: RFC 5961 5.2 Blind Data Injection Attack
Mitigation) I added more safety tests.

But we missed fact that these tests are not performed if ACK bit is
not set.

RFC 793 3.9 mandates TCP should drop a frame without ACK flag set.

" fifth check the ACK field,
      if the ACK bit is off drop the segment and return"

Not doing so permits an attacker to only guess an acceptable sequence
number, evading stronger checks.

Many thanks to Zhiyun Qian for bringing this issue to our attention.

Unfortunately with !CONFIG_PAGEFLAGS_EXTENDED, (!PageHead) is false, and
(PageHead) is true, for tail pages.  If this is indeed the intended
behavior, which I doubt because it breaks cache cleaning on some ARM
systems, then the nomenclature is highly problematic.

This patch makes sure PageHead is only true for head pages and PageTail
is only true for tail pages, and neither is true for non-compound pages.

[ This buglet seems ancient - seems to have been introduced back in Apr
  2008 in commit 6a1e7f77: "pageflags: convert to the use of new
  macros".  And the reason nobody noticed is because the PageHead()
  tests are almost all about just sanity-checking, and only used on
  pages that are actual page heads.  The fact that the old code returned
  true for tail pages too was thus not really noticeable.   - Linus ]
