The current Realtek driver reconfigures the max PCM channels
dynamically according to the value of Channel Mode enum if the
multi-io retasking is available. It works fine for multi-io pins.
But when multiple speaker pins are available, the channels of speakers
also have to obey to the channel mode, which isn't nice.
(That is, when you select "2ch" in Channel Mode so that the line-in
and mic jack behave as input, you can't play surrounds properly from
the built-in speaker.)
This patch fixes the problem by taking the channel number for multiple
speakers into account in the channel-mode setup code.
Also it fixes the wrongly set up max_channels value in the case of
multi-io extension.

ASoC: Updates for v3.8
Very quiet release for ASoC really:
- Standardisation of the logging.
- DT and dmaengine support for Atmel.
- Support for Wolfson ADSP cores.
- New drivers for Freescale/iVeia P1022 and Maxim MAX98090.

The machine driver try to use GPIO15 of twl4030 for HS MUX which supposed to
select between TWL's HSOL/R and tlv320aic3254's HPL/R.
The TWL's GPIO allocated dynamically so the (OMAP_MAX_GPIO_LINES + 15) is no
longer valid GPIO number causing a kernel crash due to BUG_ON()
Also the current machine driver supports only TWL audio currently: there is
no need to control the GPIO.

Currently the WM8994 driver allows the WM8958 microphone detection code to
be replaced in its entirety, providing a default implementation. This
doesn't actually reflect the needs of users well. They generally wish to
replace only the accessory identification parts of the algorithm (eg,
using an external GPIO to provide the equivalent of the JACKDET support in
the WM1811A).
In preparation for supporting these users better refactor the existing code
so that we have separate identification and button detection callbacks,
selecting between them rather than using the mic_detecting flag in the
existing callback. This also simplifies the code by introducing a more
explicit state machine for the detecting and button states.
In anticipation of future refactoring the callback is left in the signature
for wm8958_mic_detect(), it will be removed at a later stage.

Jack detection will not do anything to help us detect a microphone when
there is a fault in the cable and the debounce we have is enough to avoid
getting an intermediate result so halt microphone detection when we detect
that one is not present.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Conflicts:
arch/x86/kernel/ptrace.c
Pull the latest RCU tree from Paul E. McKenney:
" The major features of this series are:
1. A first version of no-callbacks CPUs. This version prohibits
offlining CPU 0, but only when enabled via CONFIG_RCU_NOCB_CPU=y.
Relaxing this constraint is in progress, but not yet ready
for prime time. These commits were posted to LKML at
https://lkml.org/lkml/2012/10/30/724, and are at branch rcu/nocb.
2. Changes to SRCU that allows statically initialized srcu_struct
structures. These commits were posted to LKML at
https://lkml.org/lkml/2012/10/30/296, and are at branch rcu/srcu.
3. Restructuring of RCU's debugfs output. These commits were posted
to LKML at https://lkml.org/lkml/2012/10/30/341, and are at
branch rcu/tracing.
4. Additional CPU-hotplug/RCU improvements, posted to LKML at
https://lkml.org/lkml/2012/10/30/327, and are at branch rcu/hotplug.
Note that the commit eliminating __stop_machine() was judged to
be too-high of risk, so is deferred to 3.9.
5. Changes to RCU's idle interface, most notably a new module
parameter that redirects normal grace-period operations to
their expedited equivalents. These were posted to LKML at
https://lkml.org/lkml/2012/10/30/739, and are at branch rcu/idle.
6. Additional diagnostics for RCU's CPU stall warning facility,
posted to LKML at https://lkml.org/lkml/2012/10/30/315, and
are at branch rcu/stall. The most notable change reduces the
default RCU CPU stall-warning time from 60 seconds to 21 seconds,
so that it once again happens sooner than the softlockup timeout.
7. Documentation updates, which were posted to LKML at
https://lkml.org/lkml/2012/10/30/280, and are at branch rcu/doc.
A couple of late-breaking changes were posted at
https://lkml.org/lkml/2012/11/16/634 and
https://lkml.org/lkml/2012/11/16/547.
8. Miscellaneous fixes, which were posted to LKML at
https://lkml.org/lkml/2012/10/30/309, along with a late-breaking
change posted at Fri, 16 Nov 2012 11:26:25 -0800 with message-ID
<20121116192625.GA447@linux.vnet.ibm.com>, but which lkml.org
seems to have missed. These are at branch rcu/fixes.
9. Finally, a fix for an lockdep-RCU splat was posted to LKML
at https://lkml.org/lkml/2012/11/7/486. This is at rcu/next. "

TCP coalescing added a regression in splice(socket->pipe) performance,
for some workloads because of the way tcp_read_sock() is implemented.
The reason for this is the break when (offset + 1 != skb->len).
As we released the socket lock, this condition is possible if TCP stack
added a fragment to the skb, which can happen with TCP coalescing.
So let's go back to the beginning of the loop when this happens,
to give a chance to splice more frags per system call.
Doing so fixes the issue and makes GRO 10% faster than LRO
on CPU-bound splice() workloads instead of the opposite.

This patch fixes both the transmit and receive portion of sending
fragmented mutlicast and broadcast packets.
The transmit section was broken because the offset for INTFRAG and
LASTFRAG packets were just miscalculated by IEEE1394_GASP_HDR_SIZE (which
was reserved with skb_push() in fwnet_send_packet).
The receive section was broken because in fwnet_incoming_packet is a call
to fwnet_peer_find_by_node_id(). Called with generation == -1 it will
not find a peer and the partial datagrams are associated to a peer.
[Stefan R: The fix to use context->card->generation is not perfect.
It relies on the IR tasklet which processes packets from the prior bus
generation to run before the self-ID-complete worklet which sets the
current card generation. Alas, there is no simple way of a race-free
implementation. Let's do it this way for now.]

The commits
3c6bdaeab4fd "[SCSI] Add a report opcode helper"
5db44863b6eb "[SCSI] sd: Implement support for WRITE SAME"
introduced in-kernel uses of the mentioned commands but cautiously
blacklisted them for any IEEE 1394 (SBP-2/3) targets and some other
transports.
I looked through a range of SBP devices and found that the blacklist
flags can be removed:
The kernel never attempts these commands if the device's INQUIRY
data claim a SCSI revision of less than 0x05. This is the case with
all SBP devices that I checked, except for three more recent devices
which claimed a revision of 0x05 i.e. conformance with SPC-3 (two
devices based on the OXUF936QSE chip but having different firmwares,
one based on OXUF934DSB.)
I tried "sg_opcodes" from sg3_utils on several older and newer devices
and did not encounter any apparent firmware bugs with it. All devices
returned Illegal Request/ Invalid command operation code and carried on.
I furthermore tried "sg_write_same -U" on the OXUF934DSB device with the
same result. Alas I did not have a TRIM enabled SSD available for these
tests. All of the bridges were correctly identified by the kernel as
"fully provisioned", CD-ROM devices aside.
The kernel won't issue WRITE SAME to fully provisioned devices, nor
would it attempt REPORT SUPPORTED OPERATION CODES or WRITE SAME with
UNMAP bit on devices which do not claim conformance to SPC-3 or later.
Hence let's remove the no_report_opcodes and no_write_same blacklist
flags so that these commands can be used on newer targets with
respective capabilities. I guess the Linux sbp-target could be such a
target.

The usual rules for open()/openat()/open_by_handle_at() are
1) native 32bit - don't force O_LARGEFILE in flags
2) native 64bit - force O_LARGEFILE in flags
3) compat on 64bit host - as for native 32bit
4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for
native 64bit
There are only two exceptions - s390 compat has open() forcing
O_LARGEFILE and arm64 compat has open_by_handle_at() doing the same
thing. The same binaries on native host (s390/31 and arm resp.) will
*not* force O_LARGEFILE, so IMO both are emulation bugs.
Objections? The fix is obvious...
