After changing content of page table(s), it is needed to notify
the other CPUs that the page table(s) have been changed so they
can do the necessary steps to use the updated version. Note that
the actual way to send IPI is SoC specific as Xtensa does not
have a common way to do this at the moment.

When kernel OOPS is raised, we need to actually go through
the process of terminating the offending thread, instead of
simply printing the stack and continue running. This change
employs similar mechanism to xtensa_arch_except() to use
illegal instruction to raise hardware exception, and going
through the fatal exception path.

Userspace support for Xtensa architecture using Xtensa MMU.
Some considerations:
- Syscalls are not inline functions like in other architectures because
some compiler issues when using multiple registers to pass parameters
to the syscall. So here we have a function call so we can use
registers as we need.
- TLS is not supported by xcc in xtensa and reading PS register is
a privileged instruction. So, we have to use threadptr to know if a
thread is an user mode thread.

With the introduction of nrfx 3.0.0, values of `nrf_gpio_pin_drive_t`
constants may be defined differently, depending on the SoC family.
Since the nrf-pinctrl.h file is included also from dts files, it is
not possible to use there different definitions of `NRF_GPIO_PIN_*`
values based on Kconfig symbols that indicate given SoC family (as
Kconfig is processed after devicetree) so that those values could
still match `nrf_gpio_pin_drive_t` constants.
To solve this problem, the pinctrl_nrf driver now uses a lookup table
for mapping `NRF_GPIO_PIN_*` indexes to drive configuration values
required by the GPIO HAL.

Use single ring buffer and protect it with a spinlock as it is

than the double ring buffer setup.

The Private Beacon Client API requires a response argument to allow to
call the API in the asynchronous manner
(https://github.com/zephyrproject-rtos/zephyr/pull/56426).
Because the removal of the EXPERIMENTAL tag for this API was not
released yet, it should be OK to change this API.
The EXPERIMENTAL tag has been removed here:

This moves the k_* memory management functions from sys/ into
kernel/ includes, as there are kernel public APIs. The z_*
functions are further separated into the kernel internal
header directory.
Also made a quick change to doxygen to group sys_mem_* into
the OS Memory Management group so they will appear in doc.

The inclusion of `fsl_common.h` solely for defining `NXP_MPU_BASE`
is redundant, as this symbol is not used. Consequently, this
unnecessary inclusion leads to the pervasive inclusion of HAL
headers through kernel headers.
The needed HAL definitions are already included into the NXP MPU
driver implementation via the SoC header.

A common pattern is used throughout llext.c:
ext->mem[ldr->sect_map[sym.st_shndx]]
where ldr->sect_map[sym.st_shndx] actually contains indices from
enum llext_section but ext->mem[] is indexed, using enum llext_mem
values. Fix this by changing ldr->sect_map[] to actually contain
enum llext_mem values.

After some further investigation, I could find the current solution to
enable zbus channels (by using ZBUS_CHAN_DECLARE) to be used in C++
files, which generates a warning when we mix C and C++ code. This fixes
the issue by using an approach to add the extern keyword only when the
file is being compiled with a C++ compiler.
