3f89482e7a Input: atarikbd - convert documentation into ReST format
This file require minimum adjustments to be a valid ReST file.
Do it, in order to be able to parse it with Sphinx.

We opted to remove section numbers, as this can be automatically
generated on Sphinx, by using :numbered: tag at index.

Pull parisc fixes from Helge Deller:
 "Al Viro reported that - in case of read faults - our copy_from_user()
  implementation may claim to have copied more bytes than it actually
  did. In order to fix this bug and because of the way how gcc optimizes
  register usage for inline assembly in C code, we had to replace our
  pa_memcpy() function with a pure assembler implementation.

  While fixing the memcpy bug we noticed some other issues with our
  get_user() and put_user() functions, e.g. nested faults may return
  wrong data. This is now fixed by a common fixup handler for
  get_user/put_user in the exception handler which additionally makes
  generated code smaller and faster.

  The third patch is a trivial one-line fix for a patch which went in
  during 4.11-rc and which avoids stalled CPU warnings after power
  shutdown (for parisc machines which can't plug power off themselves).

  Due to the rewrite of pa_memcpy() into assembly this patch got bigger
  than what I wanted to have sent at this stage.

  Those patches have been running in production during the last few days
  on our debian build servers without any further issues"

Here are some small fixes for some serial drivers and Kconfig help text
 for 4.11-rc5.  Nothing major here at all, a few things resolving
 reported bugs in some random serial drivers.
 
 I don't think these made the last linux-next due to me getting to them
 yesterday, but I am not sure, they might have snuck in.  The patches
 only affect drivers that the maintainers of sent me these patches for,
 so we should be safe here :)

f069b5a0b2 Input: bma150 - remove support for bma150
This essentially reverts commit baf28d91e7 ("Input: bma150 - avoid
binding to bma180 if IIO bma180 driver present") and commit ef3714fdbc
("Input: bma150 - extend chip detection for bma180")

Rationale: initially (2012) the GTA04 device using a bma180 chip simply
referenced the bma150 platform driver in its board file [1] which happened
to work in all scenarios that were tested.

When conversion to DT started (2014), we needed to make the driver be still
recognised. Hence we introduced the compatibility to the bma180 chip in
Linux 3.15-rc5 [2] without further checks if it is really 100% compatible.
This worked flawlessly for years with the GTA04 device.

Recently (2016), Hans de Goede pointed out that the chips are not as
similar as they appeared and the driver works with the bma180 for the GTA04
only by good luck. He proposed to remove the bma180 support completely [3],
but we still did need it until we have a replacement. Thus, a conditional
compile was added.

We have now developed a generic iio-input-bridge which works with any 2 or
3 axis iio based accelerometer. It has been tested on GTA04 and Pyra and
works as expected. Therefore we can remove the bma180 support from this
driver completely. User-space API compatibility can be restored by using
the iio-input-bridge.

Maybe it is time to convert the bma150 driver to iio as well and retire the
accelerometer input drivers completely but this is a different story and
task.
