Ulf Magnusson bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

Ulf Magnusson 975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

This commit extends the CAN API with the following functions:
- can_get_state

This functions can be used to get the error-counters and the state

from bus-off state when automatic recovery is disabled.

Henrik Brix Andersen 8940c25145 drivers: can: flexcan: disable self-reception and support listen-only
Add work-around for the NXP MCUxpresso SDK not exposing APIs for
setting the listen-only (LOM) bit of the FlexCAN MCR register and the
self-reception disable (SRXDIS) bit of the CTRL1 register.

These bits can only be written when the FlexCAN module is in freeze
mode. Add a set of simplified functions (not supporting errata 9595) for
entering/exiting freeze mode.

This work-around can be removed again once the NXP MCUxpresso SDK
exposes the needed functionality.

Andy Ross 075c94f6e2 kernel: Port remaining syscalls to new API
These calls are not accessible in CI test, nor do they get built on
common platforms (in at least one case I found a typo which proved the
code was truly unused).  These changes are blind, so live in a
separate commit.  But the nature of the port is mechanical, all other
syscalls in the system work fine, and any errors should be easily
corrected.
