b9e0669429 platform/x86: Simplify intel_mid_powerbtn
This patch:
1. Removes unnecessay #defines
2. Removes 'mfld_pb_priv' data structure which results in simpler error
   handling and less memory allocations.

c4bae98c4f acerhdf: Clean up includes
* The acerhdf driver isn't an ACPI driver, so it needs not include
  <acpi/acpi_drivers.h>. All it uses is ec_read() and ec_write(), for
  which <linux/acpi.h> is sufficient.
* I couldn't find any reason why <linux/fs.h> and <linux/sched.h> were
  included.

This should avoid unneeded rebuilds of the acerhdf driver.

e569b223d5 acerhdf: Drop pointless dependency on THERMAL_HWMON
The THERMAL_HWMON config option simply exposes the thermal zone
temperature values and limits to user-space. It makes no sense for a

2. registers in the rfkill subsystem here: /sys/class/rfkill/rfkillX/
   for these components: wifi, bluetooth, wwan (3g), gps

f133ecca9c arch/tile: more /proc and /sys file support
This change introduces a few of the less controversial /proc and
/proc/sys interfaces for tile, along with sysfs attributes for
various things that were originally proposed as /proc/tile files.
It also adjusts the "hardwall" proc API.

Arnd Bergmann reviewed the initial arch/tile submission, which
included a complete set of all the /proc/tile and /proc/sys/tile
knobs that we had added in a somewhat ad hoc way during initial
development, and provided feedback on where most of them should go.

One knob turned out to be similar enough to the existing
/proc/sys/debug/exception-trace that it was re-implemented to use
that model instead.

Another knob was /proc/tile/grid, which reported the "grid" dimensions
of a tile chip (e.g. 8x8 processors = 64-core chip).  Arnd suggested
looking at sysfs for that, so this change moves that information
to a pair of sysfs attributes (chip_width and chip_height) in the
/sys/devices/system/cpu directory.  We also put the "chip_serial"
and "chip_revision" information from our old /proc/tile/board file
as attributes in /sys/devices/system/cpu.

Other information collected via hypervisor APIs is now placed in
/sys/hypervisor.  We create a /sys/hypervisor/type file (holding the
constant string "tilera") to be parallel with the Xen use of
/sys/hypervisor/type holding "xen".  We create three top-level files,
"version" (the hypervisor's own version), "config_version" (the
version of the configuration file), and "hvconfig" (the contents of
the configuration file).  The remaining information from our old
/proc/tile/board and /proc/tile/switch files becomes an attribute
group appearing under /sys/hypervisor/board/.

Finally, after some feedback from Arnd Bergmann for the previous
version of this patch, the /proc/tile/hardwall file is split up into
two conceptual parts.  First, a directory /proc/tile/hardwall/ which
contains one file per active hardwall, each file named after the
hardwall's ID and holding a cpulist that says which cpus are enclosed by
the hardwall.  Second, a /proc/PID file "hardwall" that is either
empty (for non-hardwall-using processes) or contains the hardwall ID.

Finally, this change pushes the /proc/sys/tile/unaligned_fixup/
directory, with knobs controlling the kernel code for handling the
fixup of unaligned exceptions.

1007da0604 ASoC: Fix dapm_is_shared_kcontrol so everything isn't shared
Commit af46800 ("ASoC: Implement mux control sharing") introduced
function dapm_is_shared_kcontrol.

When this function returns true, the naming of DAPM controls is derived
from the kcontrol_new. Otherwise, the name comes from the widget (and
possibly a widget's naming prefix).

A bug in the implementation of dapm_is_shared_kcontrol made it return 1
in all cases. Hence, that commit caused a change in control naming for
all controls instead of just shared controls.

Specifically, a control is always considered shared because it is always
compared against itself. Solve this by never comparing against the widget
containing the control being created.

Equally, controls should never be shared between DAPM contexts; when the
same codec is instantiated multiple times, the same kcontrol_new will be
used. However, the control should no be shared between the multiple
instances.

I tested that with the Tegra WM8903 driver:
* Shared is now mostly 0 as expected, and sometimes 1.
* The expected controls are still generated after this change.

However, I don't have any systems that have a widget/control naming
prefix, so I can't test that aspect.

Thanks for Jarkko Nikula for pointing out how to fix this.
