741ff96613 irqchip/exynos-combiner: Consolidate chained IRQ handler install/remove
Chained irq handlers usually set up handler data as well. We now have
a function to set both under irq_desc->lock. Replace the two calls
with one.

Search and conversion was done with coccinelle:

41a83e06e2 irqchip: Prepare for local stub header removal
The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
the local irqchip.h became an empty shell, which solely includes
include/linux/irqchip.h

Include the global header in all irqchip drivers instead of the local
header, so we can remove it.

d452bca82d irqchip/sirfsoc: Fix generic chip allocation wreckage
irq_alloc_domain_generic_chips() can only be called once for an
irqdomain. The sirfsoc init calls it twice and because the return
value is not checked it does not notice the wreckage.

The code works by chance because the first call already allocates two
chips and therefor the second call to sirfsoc_alloc_gc() operates on
the proper generic chip instance.

Use a single call and setup the two chips in the obvious correct way.

b66231183a irqchip/dw-apb-ictl: Fix generic domain chip wreckage
The num_ct argument of irq_alloc_domain_generic_chips() tells the core
code how many chip types (for different control flows,
e.g. edge/level) should be allocated. It does not control how many
generic chip instances are created because that's determined from the
irq domain size and the number of interrupts per chip.

The dw-apb init abuses the num_ct argument for allocating one or two
chip types depending on the number of interrupts. That's completely
wrong because the alternate type is never used.

This code was obviously never tested on a system which has more than
32 interrupts as that would have never worked due to the unitialized
second generic chip instance.

Hand in the proper num_ct=1 and fixup the chip initialization along
with the interrupt handler.

84e3e9d04d ARM: SoC: fixes for v4.2-rc2
A fairly random colletion of fixes based on -rc1 for OMAP, sunxi and
 prima2 as well as a few arm64-specific DT fixes.
 
 This series also includes a late to support a new Allwinner (sunxi)
 SoC, but since it's rather simple and isolated to the
 platform-specific code, it's included it for this -rc.

8fc2b61a36 ath9k: DFS - add pulse chirp detection for FCC
FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.

A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range

The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

The chip reports radar pulses on extension channel
even if operating in HT20 mode. This patch adds a
sanity check for HT40 mode before it feeds pulses
on extension channel to the pattern detector.

commit 2c86c27501 ("Add ipw2100 wireless driver.") introduced
HW_PHY_OFF_LOOP_DELAY (HZ / 5000) which always evaluated to 0. Clarified

75509fd88f nsfs: Add a show_path method to fix mountinfo
Today mountinfo displays a very unhelpful "/" for nsfs files.  Add a
show_path method returning the same string as ns_dname.  This results
in a bind mount of /proc/<pid>/ns/net showing up in /proc/<pid>/mountinfo as
"net:[1234...]" instead of "/".

ed25b113a9 ath10k: tweak interface combinations
Concurrent AP/GO operation on different channels
isn't really supported well by the firmware so
it's better to remove it from being advertised.

Also tune the way station and p2p client interface
limits are expressed to allow station + 2x p2p
client or station + p2p client + p2p go.

acd0b27bb1 ath10k: fix per-vif queue locking
Whenever any vdev was supposed to be paused all Tx
queues were stopped (except offchannel) instead of
only these associated with the given vdev.

This caused subtle issues with
multi-channel/multi-vif scenarios, e.g.
authentication of station vif could sometimes fail
depending on fw tx pause request timing.

f23e587e55 ath10k: update vdev ps state on start
Psmode can be forcefully enabled when vdev isn't
started. It isn't guaranteed that mac80211 will
re-issue psmode setting after vdev is started
unless actual bss_conf.ps value has changed.

Even if this doesn't fix any problems now it may
prevent future breakage.

424f263014 ath10k: limit multi-vif ps more aggresivelly
Further testing proved that multi-channel AP+STA
on QCA6174 with RM.2.0-00088 should have powersave
force-disabled to avoid beacon misses/skipping on
either side which in turn could disrupt
communication.

Since AP never has arvif->ps don't even bother
checking it. Other combinations may be broken as
well so disallow powersave with multivif outright
unless firmware advertises otherwise.
