We are setting CONFIG_GEN_PRIV_STACKS when AArch64 actually uses a
statically allocated privileged stack.
This error was not captured by the tests because we only verify whether
a read/write to a privileged stack is failing, but it can fail for a lot
of reasons including when the pointer to the privileged stack is not
initialized at all, like in this case.
With this patch we deselect CONFIG_GEN_PRIV_STACKS and we fix the
mem_protect/userspace test to correctly probe the privileged stack.

* Rename CPU_ARCV2 to ISA_ARCV2. That helps to avoid conflict between
CPU families naming and ISAs naming and aligns this options
with other ARC OSS projects.
* Generalize ARCV2 check to ARC check where it is required.
NOTE: we add ISA_ARCV2 option in a choice list as a preparation
for ISA_ARCV3 addition.

Shell uninitialization is not synchronous, it is deferred to shell
thread so resources used by the shell (e.g. transport resource like
uart) cannot be used until it is completed. Added callback which
notifies when all resources are released and shell is uninitialized.
Callback is called from shell thread just before it is aborted.

Add Z_SHELL_SET_FLAG_ATOMIC macro to use technique from
shell_process() to atomically set and return the previous
value.
Change all void z_flag_*_set() functions to bool z_flag_*_set()
and use macro to return previous value after setting.
Modify shell_process() to use this modified z_flag_processing_set()
function.
Reorder flags to keep last_nl on byte boundary.
Add public setters for insert_mode, echo, and mode_delete for
completeness.

Channel direction was actually a source of confusion since the spec does
actually define the data path direction from controller point of view
meaning input actually means transmit and output receive, also direction
can be configured with different QoS settings.
To make these APIs less confusing and allow QoS to be configured
independently they are now split into RX (receiving) and TX
(transmission) settings including its data path.

This fixes bt_iso_cleanup when there are still channels bound to the
ACL connection.
On top of it introduce bt_iso_chan_unbind which can be used to unbind
channels and thus release the reference to the ACL connection if that
has not been disconnected in which case the channels are unbind
automatically.

Add initial support for the Cortex-M55 Core which is an implementation

M‑profile Vector Extension (MVE).
The support is based on the Cortex-M33 support that already exists in
Zephyr.

net_eth_carrier_on() and net_eth_carrier_off() call k_work_init() on
work item that can be pending or still be processed in another thread.
This results in undefined behavior.
Initialize work item once and use an atomic flag to switch between
up/down carrier state. Submit work to workqueue whenever up/down carrier
state changes, so that last state is always properly propagated to
network interface layer.
While at it, save network interface pointer during ethernet context
initialization, so that is becomes static (and thread-safe) during whole
ethernet context lifetime.

Since linker_final_pass.cmd is the actual linker script being

Using this actually would result in a linker input section being
put between output sections which is not correct syntax.
We have never seen this simply because the generated ones would
be included instead of the in-tree ones. So remove this just in
case, instead of linker errors.

Removed k_pipe_block_put and static functions only related to it.
After all the old usage of k_mem_block has been replaced by k_heap,
k_pipe_block_put still taking a deprecated k_mem_block as argument
becomes dead code. All APIs that hook it from kernel.h have been
confirmed to be removed. Since an asynchronous message descriptor
is only allocated in k_pipe_block_put, static functions for pipe_
async are removed as well.

STATUS32.DZ(bit 13) is the EV_DivZero exception enable bit, and it's
not enabled by default. we need to set it explicitly to enable divide
zero exception on early boot and each thread's setup.
The DZ bit is ignored on write and read as zero when there is no
hardware division configured. So we can simply set DZ bit even if
there is no hardware division configured.
