4b3fd57138 IPVS: Change sock_create_kernel() to __sock_create()
The recent netns changes omitted to change
sock_create_kernel() to __sock_create() in ip_vs_sync.c

The effect of this is that the interface will be selected in the
root-namespace, from my point of view it's a major bug.

93789b32db x86, hotplug: Fix powersavings with offlined cores on AMD
ea53069231 made a CPU use monitor/mwait
when offline. This is not the optimal choice for AMD wrt to powersavings
and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the
same selection whether to use monitor/mwait has to be used as when we
select the idle routine for the machine.

With this patch, offlining cores 1-5 on a X6 machine allows core0 to
boost again.

[ hpa: putting this in urgent since it is a (power) regression fix ]

23624935e0 net_sched: TCQ_F_CAN_BYPASS generalization
Now qdisc stab is handled before TCQ_F_CAN_BYPASS test in
__dev_xmit_skb(), we can generalize TCQ_F_CAN_BYPASS to other qdiscs
than pfifo_fast : pfifo, bfifo, pfifo_head_drop and sfq

SFQ is special because it can have external classifiers, and in these
cases, we cannot bypass queue discipline (packet could be dropped by
classifier) without admin asking it, or further changes.

Its worth doing this, especially for SFQ, avoiding dirtying memory in
case no packets are already waiting in queue.

f35c0c5609 iwlwifi: initial P2P support
If PAN functionality is present, advertise
P2P interface type support and thus support
for P2P. However, the support is currently
somewhat incomplete -- NoA schedule isn't
added to probe responses, and 11b bitrates

all optional with a Kconfig option.

the sram data dumped through the debugfs interface would only work properly
when dumping data on even u32 boundaries and swap bytes based on endianness
on that boundary making byte arrays impossible to read.

now addresses are displayed at the start of every line and the data is
displayed consistently if dumping 1 byte or 20 and regardless of what is the
starting address.

55f6d0fff6 ath9k: Add 'misc' file to debugfs, fix queue indexes.
Add a misc file to show hardware op-mode, irq setup,
number of various types of VIFs and more.

Also, previous patches were using the wrong xmit queue
indexes.  Change to use the internal ath9k indexes instead
of the mac80211 queue indexes.

59eb21a650 cfg80211: Extend channel to frequency mapping for 802.11j
Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
channel numbers in the 2GHz and 5GHz band we can't map from channel to
frequency without knowing the band. This is no problem as in most contexts we
know the band. In places where we don't know the band (and WEXT compatibility)
we assume the 2GHz band for channels below 14.

This patch does not implement all channel to frequency mappings defined in
802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
channels as well as 802.11y channels have been omitted.

The following drivers have been updated to reflect the API changes:
iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx.
The drivers have been compile-tested only.

60f2d1d506 ath9k: Restart xmit logic in xmit watchdog.
The system can get into a state where the xmit queue
is stopped, but there are no packets pending, so
the queue will not be restarted.

Add logic to the xmit watchdog to attempt to restart
the xmit logic if this situation is detected.

Example 'dmesg' output:

ath: txq: f4e723e0 axq_qnum: 2, mac80211_qnum: 2 axq_link: f4e996c8 pending frames: 1 axq_acq empty: 1 stopped: 0 axq_depth: 0  Attempting to restart tx logic.

7f010c93d7 ath9k: Keep track of stations for debugfs.
The stations hold the ath_node, which holds the tid
and other xmit logic structures.  In order to debug
stuck xmit logic, we need a way to print out the tid
state for the stations.
