56ff51084e mac80211: clean up station debugfs
Remove items that can be retrieved through nl80211. This also
removes two items (tx_packets and tx_bytes) where only the VO
counter was exposed since they are split up per AC but in the
debugfs file only the first AC was shown.

Also remove the useless "dev" file - the stations have long
been in a sub-directory of the netdev so there's no need for
that any more.

f83f1c129a mac80211: remove sta->tx_fragments counter
This counter is unsafe with concurrent TX and is only exposed
through debugfs and ethtool. Instead of trying to fix it just
remove it for now, if it's really needed then it should be
exposed through nl80211 and in a way that drivers that do the
fragmentation in the device could support it as well.

c206ca6709 mac80211: move dot11 counters under MAC80211_DEBUG_COUNTERS
Since these counters can only be read through debugfs, there's
very little point in maintaining them all the time. However,
even just making them depend on debugfs is pointless - they're
not normally used. Additionally a number of them aren't even
concurrency safe.

Move them under MAC80211_DEBUG_COUNTERS so they're normally
not even compiled in.

b9a95e85bb Revert "arm64: alternative: Allow immediate branch as alternative instruction"
This reverts most of commit fef7f2b201.

It turns out that there are a couple of problems with the way we're
fixing up branch instructions used as part of alternative instruction
sequences:

  (1) If the branch target is also in the alternative sequence, we'll
      generate a branch into the .altinstructions section which actually
      gets freed.

  (2) The calls to aarch64_insn_{read,write} bring an awful lot more
      code into the patching path (e.g. taking locks, poking the fixmap,
      invalidating the TLB) which isn't actually needed for the early
      patching run under stop_machine, but makes the use of alternative
      sequences extremely fragile (as we can't patch code that could be
      used by the patching code).

Given that no code actually requires alternative patching of immediate
branches, let's remove this support for now and revisit it when we've
got a user. We leave the updated size check, since we really do require
the sequences to be the same length.

e8a4a2696f x86/spinlocks: Fix regression in spinlock contention detection
A spinlock is regarded as contended when there is at least one waiter.
Currently, the code that checks whether there are any waiters rely on
tail value being greater than head. However, this is not true if tail
reaches the max value and wraps back to zero, so arch_spin_is_contended()
incorrectly returns 0 (not contended) when tail is smaller than head.

The original code (before regression) handled this case by casting the
(tail - head) to an unsigned value. This change simply restores that
behavior.

97372e5a99 clk: exynos5420: Restore GATE_BUS_TOP on suspend
Commit ae43b32891 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power
Management support v12") added pm support for the pl330 dma driver but
it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated
during suspend and this in turn makes its parent clock aclk266_g2d to
be gated. But the clock needs to be ungated prior suspend to allow the
system to be suspend and resumed correctly.

Add GATE_BUS_TOP register to the list of registers to be restored when
the system enters into a suspend state so aclk266_g2d will be ungated.

Thanks to Abhilash Kesavan for figuring out that this was the issue.

9ba52e5812 blk-mq: don't lose requests if a stopped queue restarts
Normally if driver is busy to dispatch a request the logic is like below:
block layer:					driver:
	__blk_mq_run_hw_queue
a.						blk_mq_stop_hw_queue
b.	rq add to ctx->dispatch

later:
1.						blk_mq_start_hw_queue
2.	__blk_mq_run_hw_queue

But it's possible step 1-2 runs between a and b. And since rq isn't in
ctx->dispatch yet, step 2 will not run rq. The rq might get lost if
there are no subsequent requests kick in.

Intel Wired LAN Driver Updates 2015-05-04

This series contains updates to igb, e100, e1000e and ixgbe.

Todd cleans up igb_enable_mas() since it should only be called for the
82575 silicon and has no clear return, so modify the function to void.

Jean Sacren found upon inspection that 'err' did not need to be
initialized, since it is immediately overwritten.

Alex Duyck provides two patches for e1000e, the first cleans up the
handling VLAN_HLEN as a part of max frame size.  Fixes the issue:
c751a3d58c ("e1000e: Correctly include VLAN_HLEN when changing
interface MTU").  The second fixes an issue where the driver was not
allowing jumbo frames to be enabled when CRC stripping was disabled,
however it was allowing CRC stripping to be disabled while jumbo frames
were enabled.

Jeff (me) fixes a warning found on PPC where the use of do_div() needed
to use u64 arg and not s64.

Mark provides three ixgbe patches, first to fix the Intel On-chip System
Fabric (IOSF) Sideband message interfaces, to serialize access using both
PHY bits in the SWFW_SEMAPHORE register.  Then fixes how semaphore bits
were released, since they should be released in reverse of the order that
they were taken.  Lastly updates ixgbe to use a signed type to hold
error codes, since error codes are negative, so consistently use signed
types when handling them.

v2: dropped the previous #6-#8 patches by Hiroshi Shimanoto based on
    feedback from Or Gerlitz (and David Miller) that it appears there
    needs to be further discussion on how this gets implemented.

commit "7085a7 (drivers: platform: parse IRQ flags from resources)" add
support in platform_get_irq to resolve irq and irq_flags respectively
for both modern device tree and legacy static platform data platforms.

Modify smsc911x driver to use platform_get_irq to pick up irq resource
correctly and use irq_get_trigger_type to get the IRQ trigger flags.

a13683f292 tipc: adjust locking policy of subscription
Currently subscriber's lock protects not only subscriber's subscription
list but also all subscriptions linked into the list. However, as all
members of subscription are never changed after they are initialized,
it's unnecessary for subscription to be protected under subscriber's
lock. If the lock is used to only protect subscriber's subscription
list, the adjustment not only makes the locking policy simpler, but
also helps to avoid a deadlock which may happen once creating a
subscription is failed.

00bc00a938 tipc: involve reference counter for subscriber
At present subscriber's lock is used to protect the subscription list
of subscriber as well as subscriptions linked into the list. While one
or all subscriptions are deleted through iterating the list, the
subscriber's lock must be held. Meanwhile, as deletion of subscription
may happen in subscription timer's handler, the lock must be grabbed
in the function as well. When subscription's timer is terminated with
del_timer_sync() during above iteration, subscriber's lock has to be
temporarily released, otherwise, deadlock may occur. However, the
temporary release may cause the double free of a subscription as the
subscription is not disconnected from the subscription list.

Now if a reference counter is introduced to subscriber, subscription's
timer can be asynchronously stopped with del_timer(). As a result, the
issue is not only able to be fixed, but also relevant code is pretty
readable and understandable.

57f1d1868f tipc: rename functions defined in subscr.c
When a topology server accepts a connection request from its client,
it allocates a connection instance and a tipc_subscriber structure
object. The former is used to communicate with client, and the latter
is often treated as a subscriber which manages all subscription events
requested from a same client. When a topology server receives a request
of subscribing name services from a client through the connection, it
creates a tipc_subscription structure instance which is seen as a
subscription recording what name services are subscribed. In order to
manage all subscriptions from a same client, topology server links
them into the subscrp_list of the subscriber. So subscriber and
subscription completely represents different meanings respectively,
but function names associated with them make us so confused that we
are unable to easily tell which function is against subscriber and
which is to subscription. So we want to eliminate the confusion by
renaming them.

d66bf7dd27 net: core: Correct an over-stringent device loop detection.
The code in __netdev_upper_dev_link() has an over-stringent
loop detection logic that actually prevents valid configurations
from working correctly.

In particular, the logic returns an error if an upper device
is already in the list of all upper devices for a given dev.
This particular check seems to be a overzealous as it disallows
perfectly valid configurations.  For example:
  # ip l a link eth0 name eth0.10 type vlan id 10
  # ip l a dev br0 typ bridge
  # ip l s eth0.10 master br0
  # ip l s eth0 master br0  <--- Will fail

If you switch the last two commands (add eth0 first), then both
will succeed.  If after that, you remove eth0 and try to re-add
it, it will fail!

It appears to be enough to simply check adj_list to keeps things
safe.

I've tried stacking multiple devices multiple times in all different
combinations, and either rx_handler registration prevented the stacking
of the device linking cought the error.

29a1ff6596 Merge branch 'igmp_mld_export'
Linus Lüssing says:

====================
Exporting IGMP/MLD checking from bridge code

The multicast optimizations in batman-adv are yet only usable and
enabled in non-bridged scenarios. To be able to support bridged setups
batman-adv needs to be able to detect IGMP/MLD queriers and reports on
mesh nodes without bridges, too. See the following link for details:

http://www.open-mesh.org/projects/batman-adv/wiki/Multicast-optimizations-listener-reports

To avoid duplicate code between the bridge and batman-adv, the IGMP/MLD
message validation code is moved from the bridge to the IPv4/IPv6 stack.

On the way, some refactoring to increase readability and to iron out
some subtle differences between the IGMP and MLD parsing code is done.

9afd85c9e4 net: Export IGMP/MLD message validation code
With this patch, the IGMP and MLD message validation functions are moved
from the bridge code to IPv4/IPv6 multicast files. Some small
refactoring was done to enhance readibility and to iron out some
differences in behaviour between the IGMP and MLD parsing code (e.g. the
skb-cloning of MLD messages is now only done if necessary, just like the
IGMP part always did).

Finally, these IGMP and MLD message validation functions are exported so
that not only the bridge can use it but batman-adv later, too.

27aa6b71d3 wil6210: support WSC for STA mode
WSC connection is secure (privacy bit set in various frames)
but authentication suite, keys etc. are absent.

Support this mode in the connect WMI command. Detect WSC by
having 'sme->privacy' and no RSN IE. Inform firmware about WSC
session by setting dot11_auth_mode to WMI_AUTH11_WSC.

Introduce 2 types of GTK, Tx (for this STA) and Rx (for each peer).
Now, AP has only Tx GTK, STA - only Rx one. PBSS not supported yet;
for it, continue using pseudo-DMS.
Handle per-vring .1x state, update it from WMI_VRING_EN_EVENTID

This mechanism replaces former per-CID "data_port_open"

dc16427bbe wil6210: Add pmc debug mechanism memory management
Pmc is a hardware debug mechanism which allows capturing phy data,
packets, and internally generated events and messages synchronized
and time stamped by the hardware. It requires memory buffers
allocated by the driver in order to be used by hardware dma to
upstream real time debug data to host memory.
Driver will handle memory allocation and release, and fetching
the data from the memory to application layer via debug file
system. The configuration of pmc is handled entirely by the
application layer.

I was also considering making this hw specific flag but as this is strictly a
firmware issue it's best to handle this via a firmware feature flag so that it

e7309c2673 bus: omap_l3_noc: Fix master id address decoding for OMAP5
The L3 Error handling on OMAP5 for the most part is very similar
to that of OMAP4, and had leveraged common data structures and
register layout definitions so far. Upon closer inspection, there
are a few minor differences causing an incorrect decoding and
reporting of the master NIU upon an error:

  1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies
     11 bits on OMAP5 as against 8 bits on OMAP4, with the master
     NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR
     field.
  2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3
     input sources on OMAP5. The common DEBUGSS source is at a
     different input on each SoC.

Fix the above issues by using a OMAP5-specific compatible property
and using SoC-specific data where there are differences.

With wrong offset these errors are not correctly cleared by the L3
IRQ handler and cause an continuous interrupt scenario and system lockup.
