0dcaa4c668 boards: arm: stm32f746 with all mpu regions when testing in userspace
Disable the  quadspi mpu region of the nucleo_f746zg
when testing the samples/userspace/shared_mem
or tests/kernel/mem_protect/userspace
The stm32f7 cortex M7 has 8 MPU regions and the one for quadspi prevents
the testcase to PASS.

befc96f22e userspace tests/samples: Exclude in posix arch
These samples & tests cannot be run in this architecture
as it does not support userspace.
Today they are filtered by kconfig, which works but spends
time running cmake.
As native_posix is a default test platform it is better
to filter it alltogether by arch, which saves quite a lot
of time.

Excluded cy8cproto_062_4343w and cy8cproto_063_ble from
samples/userspace/shared_mem sample due to a hardware
limitation with number of available MPU regions.
Sample throws warning:

With the Cortex M4 on the boards only 2 mpu regions are left
and available to be used with the sample.

0b90fd5adf samples, tests, boards: Switch main return type from void to int
As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.

Most of these changes were automated using coccinelle with the following
script:

@@
@@
- void
+ int
main(...) {
	...
-	return;
+	return 0;
	...
}

Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

bb595a85f1 kernel: mem_domain: add/remove partition funcs to return errors
This changes both k_mem_domain_add_partition() and
k_mem_domain_remove_partition() to return errors instead of
asserting when errors are encountered. This gives the application
chance to recover.

The arch_mem_domain_parition_add()/_remove() will be modified
later together with all the other arch_mem_domain_*() changes
since the architecture code for partition addition and removal
functions usually cannot be separately changed.

407b49b35c cmake: use find_package to locate Zephyr
Using find_package to locate Zephyr.

Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.

Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.

It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

9e37e80a1d samples/userspace/shared_mem: Add volatile to interthread data
This test uses bare variables to synchronize state between threads,
but had forgotten volatile qualifiers on all the data.  So the
compiler was free to reorder and make assumptions that aren't valid
when the values are being written from other CPUs.

Single-cpu operation was fine because the code would always hit an
external function call like k_sleep() that would force it to re-read
from memory every time there was a context switch (timeslicing isn't
enabled on this test and the threads are cooperative), but on SMP the
volatiles can change at any time and we could see spurious state
mixups and hangs.
