The KVM API documentation is not clear about the semantics of the data
field on the mmio struct on the kvm_run struct.
This has become problematic when supporting ARM guests on big-endian
host systems with guests of both endianness types, because it is unclear
how the data should be exported to user space.
This should not break with existing implementations as all supported
existing implementations of known user space applications (QEMU and
kvmtools for virtio) only support default endianness of the
architectures on the host side.

The previous commit "ACPICA: Add auto-serialization support for ill-behaved
control methods" introduced the auto-serialization facility as a workaround
that can be enabled by "acpi_auto_serialize":
This feature marks control methods that create named objects as "serialized"
to avoid unwanted AE_ALREADY_EXISTS control method evaluation failures.
Enable method auto-serialization as the default kernel behavior. The new kernel
parameter is also changed from "acpi_auto_serialize" to "acpi_no_auto_serialize"
to reflect the default behavior.

This change adds support to automatically mark a control method as
"serialized" if the method creates any named objects. This will
positively prevent the method from being entered by more than one
thread and thus preventing a possible abort when an attempt is
made to create an object twice.
Implemented by parsing all non-serialize control methods at table
load time.
This feature is disabled by default and this patch also adds a new
Linux kernel parameter "acpi_auto_serialize" to allow this feature
to be turned on for a specific boot.

According to the reports, the "acpi_serialize" mechanism is broken as:
A. The parallel method calls can still happen when the interpreter lock is
released under the following conditions:
1. External callbacks are invoked, for example, by the region handlers,
the exception handlers, etc.;
2. Module level execution is performed when Load/LoadTable opcodes are
executed, and
3. The _REG control methods are invoked to complete the region
registrations.
B. For the following situations, the interpreter lock need to be released
even for a serialized method while currently, the lock-releasing
operation is marked as a no-op by
acpi_ex_relinquish/reacquire_interpreter() when this mechanism is
enabled:
1. Wait opcode is executed,
2. Acquire opcode is executed, and
3. Sleep opcode is executed.
This patch removes this mechanism and the internal
acpi_ex_relinquish/reacquire_interpreter() APIs. Lv Zheng.

John W. Linville says:
====================
Please pull this batch of wireless updates intended for 3.15!
For the mac80211 bits, Johannes says:
"This has a whole bunch of bugfixes for things that went into -next
previously as well as some other bugfixes I didn't want to rush into
3.14 at this point. The rest of it is some cleanups and a few small
features, the biggest of which is probably Janusz's regulatory DFS CAC
time code."
For the Bluetooth bits, Gustavo says:
"One more pull request to 3.15. This is mostly and bug fix pull request, it
contains several fixes and clean up all over the tree, plus some small new
features."
For the NFC bits, Samuel says:
"This is the NFC pull request for 3.15. With this one we have:
- Support for ISO 15693 a.k.a. NFC vicinity a.k.a. Type 5 tags. ISO
15693 are long range (1 - 2 meters) vicinity tags/cards. The kernel
now supports those through the NFC netlink and digital APIs.
- Support for TI's trf7970a chipset. This chipset relies on the NFC
digital layer and the driver currently supports type 2, 4A and 5 tags.
- Support for NXP's pn544 secure firmare download. The pn544 C3 chipsets
relies on a different firmware download protocal than the C2 one. We
now support both and use the right one depending on the version we
detect at runtime.
- Support for 4A tags from the NFC digital layer.
- A bunch of cleanups and minor fixes from Axel Lin and Thierry Escande."
For the iwlwifi bits, Emmanuel says:
"We were sending a host command while the mutex wasn't held. This
led to hard-to-catch races."
And...
"I have a fix for a "merge damage" which is not really a merge
damage: it enables scheduled scan which has been disabled in
wireless.git. Since you merged wireless.git into wireless-next.git,
this can now be fixed in wireless-next.git.
Besides this, Alex made a workaround for a hardware bug. This fix
allows us to consume less power in S3. Arik and Eliad continue to
work on D0i3 which is a run-time power saving feature. Eliad also
contributes a few bits to the rate scaling logic to which Eyal adds his
own contribution. Avri dives deep in the power code - newer firmware
will allow to enable power save in newer scenarios. Johannes made a few
clean-ups. I have the regular amount of BT Coex boring stuff. I disable
uAPSD since we identified firmware bugs that cause packet loss. One
thing that do stand out is the udev event that we now send when the
FW asserts. I hope it will allow us to debug the FW more easily."
Also included is one last iwlwifi pull for a build breakage fix...
For the Atheros bits, Kalle says:
"Michal now did some optimisations and was able to improve throughput by
100 Mbps on our MIPS based AP135 platform. Chun-Yeow added some
workarounds to be able to better use ad-hoc mode. Ben improved log
messages and added support for MSDU chaining. And, as usual, also some
smaller fixes."
Beyond that...
Andrea Merello continues his rtl8180 refactoring, in preparation for
a long-awaited rtl8187 driver. We get a new driver (rsi) for the
RS9113 chip, from Fariya Fatima. And, of course, we get the usual
round of updates for ath9k, brcmfmac, mwifiex, wil6210, etc. as well.

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:
- Lots of cleanups from Takashi for enumerations; the original API for
these was error prone so he's refactored lots of code to use more
modern APIs which avoid issues.
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle.
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues.
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues.
- DPCM support for Intel Haswell and Bay Trail platforms.
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:
- Lots of cleanups from Takashi for enumerations; the original API for
these was error prone so he's refactored lots of code to use more
modern APIs which avoid issues.
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle.
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues.
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues.
- DPCM support for Intel Haswell and Bay Trail platforms.
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
CSR SiRF SoC.

With this patch a multicast packet is not always simply flooded anymore,
the behaviour for the following cases is changed to reduce
unnecessary overhead:
If all nodes within the horizon of a certain node have signalized
multicast listener announcement capability then an IPv6 multicast packet
with a destination of IPv6 link-local scope (excluding ff02::1) coming
from the upstream of this node...
* ...is dropped if there is no according multicast listener in the
translation table,
* ...is forwarded via unicast if there is a single node with interested
multicast listeners
* ...and otherwise still gets flooded.

This callback allows the driver to do clean up before the CPU is
completely down and its state cannot be modified. This is used
by the intel_pstate driver to reduce the requested P state prior to
the core going away. This is required because the requested P state
of the offline core is used to select the package P state. This
effectively sets the floor package P state to the requested P state on
the offline core.

The current simple-card driver separates the daimft for cpu_dai and codec_dai.
So we might get different values for them (0x4003 and 0x1003 for example):
asoc-simple-card sound-cs42888.12: cpu : 2024000.esai / 4003 / 132000000
asoc-simple-card sound-cs42888.12: codec : cs42888 / 1003 / 24576000
asoc-simple-card sound-cs42888.12: cs42888 <-> 2024000.esai mapping ok
This is not allowed at all as we need to keep the DAIFMT settings identical
for both the ends of the link.
Thus this patch fixes it by overwriting the cpu_dai->fmt with codec_dai->fmt
since we defined the DAIFMT_MASTER basing on CODEC at the first place while
the other bits are same.

Pull networking fixes from David Miller:
"I know this is a bit more than you want to see, and I've told the
wireless folks under no uncertain terms that they must severely scale
back the extent of the fixes they are submitting this late in the
game.
Anyways:
1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
is the correct implementation, like it should. Instead it does
something like a NAPI poll operation. This leads to crashes.
From Neil Horman and Arnd Bergmann.
2) Segmentation of SKBs requires proper socket orphaning of the
fragments, otherwise we might access stale state released by the
release callbacks.
This is a 5 patch fix, but the initial patches are giving
variables and such significantly clearer names such that the
actual fix itself at the end looks trivial.
From Michael S. Tsirkin.
3) TCP control block release can deadlock if invoked from a timer on
an already "owned" socket. Fix from Eric Dumazet.
4) In the bridge multicast code, we must validate that the
destination address of general queries is the link local all-nodes
multicast address. From Linus Lüssing.
5) The x86 BPF JIT support for negative offsets puts the parameter
for the helper function call in the wrong register. Fix from
Alexei Starovoitov.
6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
r8169 driver is incorrect. Fix from Hayes Wang.
7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
if a packet is a GSO frame, but that's not the correct test. It
should use skb_is_gso(skb) instead. Fix from Wei Liu.
8) Negative msg->msg_namelen values should generate an error, from
Matthew Leach.
9) at86rf230 can deadlock because it takes the same lock from it's
ISR and it's hard_start_xmit method, without disabling interrupts
in the latter. Fix from Alexander Aring.
10) The FEC driver's restart doesn't perform operations in the correct
order, so promiscuous settings can get lost. Fix from Stefan
Wahren.
11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.
12) Reference count and memory leak fixes in TIPC from Ying Xue and
Erik Hugne.
13) Forced eviction in inet_frag_evictor() must strictly make sure all
frags are deleted, otherwise module unload (f.e. 6lowpan) can
crash. Fix from Florian Westphal.
14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
uses as a hash function), which breaks on PowerPC. From Anton
Blanchard.
The main gist of the issue is that csum_partial() is defined only
as a value that, once folded (f.e. via csum_fold()) produces a
correct 16-bit checksum. It is legitimate, therefore, for
csum_partial() to produce two different 32-bit values over the
same data if their respective alignments are different.
15) Fix endiannes bug in MAC address handling of ibmveth driver, also
from Anton Blanchard.
16) Error checks for ipv6 exthdrs offload registration are reversed,
from Anton Nayshtut.
17) Externally triggered ipv6 addrconf routes should count against the
garbage collection threshold. Fix from Sabrina Dubroca.
18) The PCI shutdown handler added to the bnx2 driver can wedge the
chip if it was not brought up earlier already, which in particular
causes the firmware to shut down the PHY. Fix from Michael Chan.
19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
currently coded it can and does trigger in legitimate situations.
From Eric Dumazet.
20) BNA driver fails to build on ARM because of a too large udelay()
call, fix from Ben Hutchings.
21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
from Eric Dumazet.
22) The vlan passthrough ops added in the previous release causes a
regression in source MAC address setting of outgoing headers in
some circumstances. Fix from Peter Boström"

The compat vDSO is a complicated hack that's needed to maintain
compatibility with a small range of glibc versions.
This removes it and replaces it with a much simpler hack: a config
option to disable the 32-bit vDSO by default.
This also changes the default value of CONFIG_COMPAT_VDSO to n --
users configuring kernels from scratch almost certainly want that
choice.

This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with
an xargs failure to pay attention to error codes). The history lists a
bunch of additional commits for the branch but the content of those
commits is actually present already but not recorded in history due to
git failing. Unfortunately xargs is used in the merge script and it
doesn't do a good job of noticing errors from the commands it invokes.

ASoC: Updates for v3.15
This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with
an xargs failure to pay attention to error codes). The history lists a
bunch of additional commits for the branch but the content of those
commits is actually present already but not recorded in history due to

This commit adds a bare bones driver support for TLV320AIC31XX family
audio codecs. The driver adds basic stereo playback trough headphone
and speaker outputs and mono capture trough microphone inputs.
The driver is currently missing support at least for mini DSP features
and jack detection. I have tested the driver only on TLV320AIC3111,
but based on the data sheets TLV320AIC3100, TLV320AIC3110, and
TLV320AIC3120 should work Ok too.
The base for the implementation was taken from:
git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx
-branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13.

Both QEMU and KVM have already accumulated a significant number of
optimizations based on the hard-coded assumption that ioapic polarity
will always use the ActiveHigh convention, where the logical and
physical states of level-triggered irq lines always match (i.e.,
active(asserted) == high == 1, inactive == low == 0). QEMU guests
are expected to follow directions given via ACPI and configure the
ioapic with polarity 0 (ActiveHigh). However, even when misbehaving
guests (e.g. OS X <= 10.9) set the ioapic polarity to 1 (ActiveLow),
QEMU will still use the ActiveHigh signaling convention when
interfacing with KVM.
This patch modifies KVM to completely ignore ioapic polarity as set by
the guest OS, enabling misbehaving guests to work alongside those which
comply with the ActiveHigh polarity specified by QEMU's ACPI tables.

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:
- Lots of cleanups from Takashi for enumerations; the original API for
these was error prone so he's refactored lots of code to use more
modern APIs which avoid issues.
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle.
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues.
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues.
- DPCM support for Intel Haswell and Bay Trail platforms.
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
CSR SiRF SoC.
