ALSA: hda - Fix IDT/STAC multiple HP detection
Due to the recent change for multiple HP as line-out switch, only
one of the multiple headphons (usually a wrong one) is toggled
and the other pins are still disabled. This causes the silent output
problem on some Dell laptops.
Also, the hp_switch check is screwed up when a line-in or a mic-in
jack exists. This is added as an additional output, but hp_switch
check doesn't take it into account.
This patch fixes these issues: simplify hp_switch check by using
the NID instead of bool, and clean up / fix the toggle of HP pins
in unsol event handler code.

dccp: Resolve dependencies of features on choice of CCID
This provides a missing link in the code chain, as several features implicitly
depend and/or rely on the choice of CCID. Most notably, this is the Send Ack Vector
feature, but also Ack Ratio and Send Loss Event Rate (also taken care of).
For Send Ack Vector, the situation is as follows:
* since CCID2 mandates the use of Ack Vectors, there is no point in allowing
endpoints which use CCID2 to disable Ack Vector features such a connection;
* a peer with a TX CCID of CCID2 will always expect Ack Vectors, and a peer
with a RX CCID of CCID2 must always send Ack Vectors (RFC 4341, sec. 4);
* for all other CCIDs, the use of (Send) Ack Vector is optional and thus
negotiable. However, this implies that the code negotiating the use of Ack
Vectors also supports it (i.e. is able to supply and to either parse or
ignore received Ack Vectors). Since this is not the case (CCID-3 has no Ack
Vector support), the use of Ack Vectors is here disabled, with a comment
in the source code.
An analogous consideration arises for the Send Loss Event Rate feature,
since the CCID-3 implementation does not support the loss interval options
of RFC 4342. To make such use explicit, corresponding feature-negotiation
options are inserted which signal the use of the loss event rate option,
as it is used by the CCID3 code.
Lastly, the values of the Ack Ratio feature are matched to the choice of CCID.
The patch implements this as a function which is called after the user has
made all other registrations for changing default values of features.
The table is variable-length, the reserved (and hence for feature-negotiation
invalid, confirmed by considering section 19.4 of RFC 4340) feature number `0'
is used to mark the end of the table.

dccp: Query supported CCIDs
This provides a data structure to record which CCIDs are locally supported
and three accessor functions:
- a test function for internal use which is used to validate CCID requests
made by the user;
- a copy function so that the list can be used for feature-negotiation;
- documented getsockopt() support so that the user can query capabilities.
The data structure is a table which is filled in at compile-time with the
list of available CCIDs (which in turn depends on the Kconfig choices).
Using the copy function for cloning the list of supported CCIDs is useful for
feature negotiation, since the negotiation is now with the full list of available
CCIDs (e.g. {2, 3}) instead of the default value {2}. This means negotiation
will not fail if the peer requests to use CCID3 instead of CCID2.

This patch limits feature (capability) negotation to the connection setup phase:
1. Although it is theoretically possible to perform feature negotiation at any

as it requires to put traffic on hold for each new negotiation.
2. As a byproduct of restricting feature negotiation to connection setup, the
feature-negotiation retransmit timer is no longer required. This part is now
mapped onto the protocol-level retransmission.
Details indicating why timers are no longer needed can be found on

This removes the acpi_irq_balance_set() interface from the PCI
interrupt link driver.
x86 used acpi_irq_balance_set() to tell the PCI interrupt link
driver to configure links to minimize IRQ sharing. But the link
driver can easily figure out whether to turn on IRQ balancing
based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of
that external interface.
It's better for the driver to figure this out at init-time. If
we set it externally via the x86 code, the interface reduces
modularity, and we depend on the fact that acpi_process_madt()

PCI: ignore bit0 of _OSC return code
Currently acpi_run_osc() checks all the bits in _OSC result code (the
first DWORD in the capabilities buffer) to see error condition. But the
bit 0, which doesn't indicate any error, must be ignored.
The bit 0 is used as the query flag at _OSC invocation time. Some
platforms clear it during _OSC evaluation, but the others don't. On
latter platforms, current acpi_run_osc() mis-detects error when _OSC is
evaluated with query flag set because it doesn't ignore the bit 0.
Because of this, the __acpi_query_osc() always fails on such platforms.

ring-buffer: buffer record on/off switch
Impact: enable/disable ring buffer recording API added
Several kernel developers have requested that there be a way to stop
recording into the ring buffers with a simple switch that can also
be enabled from userspace. This patch addes a new kernel API to the
ring buffers called:
tracing_on()
tracing_off()
When tracing_off() is called, all ring buffers will not be able to record
into their buffers.
tracing_on() will enable the ring buffers again.
These two act like an on/off switch. That is, there is no counting of the
number of times tracing_off or tracing_on has been called.
A new file is added to the debugfs/tracing directory called
tracing_on
This allows for userspace applications to also flip the switch.
echo 0 > debugfs/tracing/tracing_on
disables the tracing.
echo 1 > /debugfs/tracing/tracing_on
enables it.
Note, this does not disable or enable any tracers. It only sets or clears
a flag that needs to be set in order for the ring buffers to write to
their buffers. It is a global flag, and affects all ring buffers.
The buffers start out with tracing_on enabled.
There are now three flags that control recording into the buffers:
tracing_on: which affects all ring buffer tracers.
buffer->record_disabled: which affects an allocated buffer, which may be set
if an anomaly is detected, and tracing is disabled.
cpu_buffer->record_disabled: which is set by tracing_stop() or if an
anomaly is detected. tracing_start can not reenable this if
an anomaly occurred.
The userspace debugfs/tracing/tracing_enabled is implemented with
tracing_stop() but the user space code can not enable it if the kernel
called tracing_stop().
Userspace can enable the tracing_on even if the kernel disabled it.
It is just a switch used to stop tracing if a condition was hit.
tracing_on is not for protecting critical areas in the kernel nor is
it for stopping tracing if an anomaly occurred. This is because userspace
can reenable it at any time.
Side effect: With this patch, I discovered a dead variable in ftrace.c
called tracing_on. This patch removes it.

ALSA: hda - Fix input pin initialization for STAC/IDT codecs
The input pins are sometimes not initialized properly because
of the optimization check of the current pinctl code.
Force to initialize the mic input pins so that they can be set up
properly even if they were in a weird state. But keep other input
pins if already set up as input, since this could be an extra mic
pin.

Input: atkbd - cancel delayed work before freeing its structure
Pointed out by Oleg Nesterov. Since delayed work is used here, use of
flush_scheduled_work() is not sufficient in atkbd_disconnect(). It does
not wait for scheduled delayed work to finish. This patch prevents
delayed work to be processed after freeing atkbd structure (used struct
delayed_work is part of atkbd) by cancelling this delayed work.

Input: atkbd - add keymap quirk for Inventec Symphony systems
The Zepto 6615WD laptop (rebranded Inventec Symphony system) needs a
key release quirk for its volume keys to work. The attached patch adds
the quirk to the atkbd driver.
Dell XPS M1530 needs i8042.nomux=1 for ALPS touchpad to work as
reported on https://qa.mandriva.com/show_bug.cgi?id=43532
It is said that before A08 bios version this isn't needed (I don't
have the hardware so can't check), and suppose this will not break
with bios versions before A08.

btrfs_drop_extents will drop paths and search again when it needs to
force COW of higher nodes. It was using the key it found during the last
search as the offset for the next search.
But, this wasn't always correct. The key could be from before our desired
range, and because we're dropping the path, it is possible for file's items
to change while we do the search again.
The fix here is to make sure we don't search for something smaller than
the offset btrfs_drop_extents was called with.

x86: apic reset counter on shutdown
Impact: avoid spurious lapic timer events on shutdown
The apic timer might be close to firing when it is shutdown. We can
not really disable the timer - we just mask the interrupt. That way we
can get an extra interrupt when it is reenabled. Set the counter to
max on shutdown to avoid this.

x86: call machine_shutdown and stop all CPUs in native_machine_halt
Impact: really halt all CPUs on halt
Function machine_halt (resp. native_machine_halt) is empty for x86
architectures. When command 'halt -f' is invoked, the message "System
halted." is displayed but this is not really true because all CPUs are
still running.
There are also similar inconsistencies for other arches (some uses
power-off for halt or forever-loop with IRQs enabled/disabled).
IMO there should be used the same approach for all architectures OR
what does the message "System halted" really mean?
This patch fixes it for x86.

sched: add hierarchical accounting to cpu accounting controller
Impact: improve CPU time accounting of tasks under the cpu accounting controller
Add hierarchical accounting to cpu accounting controller and include
cpuacct documentation.
Currently, while charging the task's cputime to its accounting group,
the accounting group hierarchy isn't updated. This patch charges the cputime
of a task to its accounting group and all its parent accounting groups.

| Add generic helpers for arch IPI function calls
didn't wire up the voyager smp call function correctly, so do that
here. Also make CONFIG_USE_GENERIC_SMP_HELPERS a def_bool y again,
since we now use the generic helpers for every x86 architecture.
