Flavio Ceolin da49f2e440 coccicnelle: Ignore return of memset
The return of memset is never checked. This patch explicitly ignore
the return to avoid MISRA-C violations.

The only directory excluded directory was ext/* since it contains

Ulf Magnusson 8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/

Diego Sueiro 72cad66c5b drivers/sensor/fxas21002: Fix race condition during initialization
A race condition was identified during the initialization of the
driver when the trigger function is enabled. This exposed two issues:

1 - The fxas21002_handle_int is trying to acquire the semaphore before
    it gets initialized. To solve this we need to initialize the
    semaphore before calling the fxas21002_trigger_init function.

2 - During the fxas21002_trigger initialization the i2c bus is used
    (from fxas21002_handle_int function) at the same time as the
    fxas21002_set_power is being called. To fix this we need to
    initialize the semaphore with 0 and just release it after calling
    the fxas21002_set_power function in the fxas21002_int

Ulf Magnusson ec3eff57e0 Kconfig: Use the first default with a satisfied condition
Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.

There are at least three problems with the patch:

  1. It's inconsistent with how Kconfig works in other projects, which
     might confuse newcomers.

  2. Due to oversights, earlier 'range' properties are still preferred,
     as well as earlier 'default' properties on choices.

     In addition to being inconsistent, this makes it impossible to
     override 'range' properties and choice 'default' properties if the
     base definition of the symbol/choice already has 'range'/'default'
     properties.

     I've seen errors caused by the inconsistency, and I suspect there
     are more.

  3. A fork of Kconfiglib that adds the patch needs to be maintained.

Get rid of the patch and go back to standard Kconfig behavior, as
follows:

  1. Include the Kconfig.defconfig files first instead of last in
     Kconfig.zephyr.

  2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
     last in arch/Kconfig.

  3. Include arch/<arch>/soc/*/Kconfig first instead of last in
     arch/<arch>/Kconfig.

  4. Swap a few other 'source's to preserve behavior for some scattered
     symbols with multiple definitions.

     Swap 'source's in some no-op cases too, where it might match the
     intent.

  5. Reverse the defaults on symbol definitions that have more than one
     default.

     Skip defaults that are mutually exclusive, e.g. where each default
     has an 'if <some board>' condition. They are already safe.

  6. Remove the prefer-later-defaults patch from Kconfiglib.

Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions

As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).

This commit includes some default-related cleanups as well:

  - Simplify some symbol definitions, e.g. where a default has 'if FOO'
    when the symbol already has 'depends on FOO'.

  - Remove some redundant 'default ""' for string symbols. This is the
    implicit default.

Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).

Piggyback some fixes for style nits too, e.g. unindented help texts.

These cases weren't caught by the heuristic used by the warning added in
commit 6eabea3a7e ("Kconfiglib: Warn for unquoted string defaults"),
because "GPIO_0" has no lowercase characters in it.

Unquoted Kconfig values are are indistinguishable from reference to

find "true" references to undefined Kconfig symbols, and makes it

Ulf Magnusson 10d54e2b22 boards: arm: argonkey: Properly set choice default
The choice symbol LSM6DSL_EXT0_LIS2MDL was given a 'default' in
Kboards/arm/96b_argonkey/Kconfig.defconfig, but 'default' has no effect
on choice symbols, triggering a warning from Kconfiglib.

Instead of adding a default to the choice symbol, change the default of
the 'choice' itself by giving it name and adding the default in
Kconfig.defconfig.

This requires that we remove the default on the "base" definition of the
'choice', due to some messiness related to the Zephyr-specific
prefer-later-defaults behavior (see the 'Zephyr-specific Kconfig
behavior for defaults' section in the Board Porting Guide). Choices were
overlooked when that patch was added to the C tools, meaning choices
still prefer earlier defaults. The crux is that Kconfig.defconfig files
are included last.

Andrew Boie 8345e5ebf0 syscalls: remove policy from handler checks
The various macros to do checks in system call handlers all
implictly would generate a kernel oops if a check failed.
This is undesirable for a few reasons:

* System call handlers that acquire resources in the handler
  have no good recourse for cleanup if a check fails.
* In some cases we may want to propagate a return value back
  to the caller instead of just killing the calling thread,
  even though the base API doesn't do these checks.

These macros now all return a value, if nonzero is returned
the check failed. K_OOPS() now wraps these calls to generate
a kernel oops.

At the moment, the policy for all APIs has not changed. They
still all oops upon a failed check/

The macros now use the Z_ notation for private APIs.

Adithya Baglody b0db28b512 drivers: Cmake: Add __ZEPHYR_SUPERVISOR__ macro for driver files.
Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.

In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.
