ASoC: tlv320aic3x: Reimplement output mixers
It turned out that the output mixers and their routes were misdefined: They
are not mixing output pins to internal signals but opposite. This has worked
for direct left-to-left and right-to-right routes since for those there are
complete routes. For swapped left-to-right and right-to-left routes this is
not working since there are no routes defined between them.
Another consequence is that those misdefined mixers are incorrectly routed
to several output pins leading unnecessary pin powerings even if there is no
route active to them.
Fix these by reimplementing the output mixers and routes as they are in
hardware. For completeness add also a few missing links between internal
signals and outputs.

mm: fix up some user-visible effects of the stack guard page
This commit makes the stack guard page somewhat less visible to user
space. It does this by:
- not showing the guard page in /proc/<pid>/maps
It looks like lvm-tools will actually read /proc/self/maps to figure
out where all its mappings are, and effectively do a specialized
"mlockall()" in user space. By not showing the guard page as part of
the mapping (by just adding PAGE_SIZE to the start for grows-up
pages), lvm-tools ends up not being aware of it.
- by also teaching the _real_ mlock() functionality not to try to lock
the guard page.
That would just expand the mapping down to create a new guard page,
so there really is no point in trying to lock it in place.
It would perhaps be nice to show the guard page specially in
/proc/<pid>/maps (or at least mark grow-down segments some way), but
let's not open ourselves up to more breakage by user space from programs
that depends on the exact deails of the 'maps' file.
Special thanks to Henrique de Moraes Holschuh for diving into lvm-tools
source code to see what was going on with the whole new warning.

As I made significant changes to the pc87427 driver, I'll be
maintaining it for the year to come.

hwmon: (pc87427) Move sysfs file removal to a separate function
The sysfs file removal code is the same in the probe error path and in
the remove function, so move it to a separate function to avoid code
duplication.

hwmon: (pc87427) Add temperature monitoring support
Add support for the 6 temperature monitoring channels of the PC87427.
Note that the sensors resolution can vary, and I couldn't find a way
to figure it out, so we might have to compensate in user-space.

hwmon: (pc87427) Add support for the second logical device
The second logical device contains the voltage and temperature
registers. We have to extend the driver to support a second logical
device before we can add support for these features.

hwmon: (pc87427) Add support for manual fan speed control
Add initial support for PWM outputs of the PC87427 Super-I/O chip.
Only mode change and manual fan speed control are supported. Automatic
mode configuration isn't supported, and won't be until at least one
board is known, which makes uses of the PWM outputs.
