reschedule the next RSSI poll.
This fixes an issue where RSSI polling would stop if for any reason
the modem doesn't fulfill an RSSI poll on time.

In arm_core_mpu_mem_partition_config_update() we must fix the
index value of the start of the for loop, to address the case
when dynamic MPU regions are programmed in index values lower
than static_regions_num. (This might occur in ARMv8-M MPU,
depending on the order of programming the map of the
dynamic regions in run-time). We introduce function
_get_dyn_region_min_index(), and provide the implementation in
arm_mpu_v8_internal.h and arm_mpu_v7_internal.h (trivial).

The ARM Cortex-M 321 application note is stressing that if
we disable interrupts by executing CPSID i(f), or by MSR
instructions (on PRIMASK, FAULTMASK registers), there is no
requirement to add barrier instructions after disabling
interupts. However, in ARMv7-M (and ARMv8-M Mainline) we use
BASEPRI, instead. Therefore, if we need the effect of disabling
interrupts to be recongnized immediately we should add barrier
instructions. This commit adds DSB and ISB barriers when
disabling interrupt using BASEPRI in the generic
arm _irq_lock() function as well as in the PendSV handler,
where we need to access kernel globals right after the interrups
are disabled.

Fix issue #14618.
The I2S controller may generate an underrun/overrun error whenever
the current sample in the Data Register (DR) has not been read/written
yet when a new one needs to be sent/received. When the DMA operation
is completed there is no much time to re-enable it for a new
transfer. For example, in the case of a PDM microphone clocked at
2MHz we only have 8us to re-program the DMA to receive the new 16-bit
sample.
Doing a complete DMA configuration using the dma_config() API is an
operation that is consuming too much time and driver is close to the
limit. Instead, the dma_reload() routine only programs the minimum
needed information (src, dst, len) for the new transfer in order
to restart the DMA.
Signed-off-by: Armando Visconti <armando.visconti@st.com>
The dma_reload() is useful when there's the need to immediately
and quickly restart the DMA for a new transfer when the current
one is completed. If the operation is not done quickly there
might be underrun or overrun errors and the data flow is broken.
The dma_reload() just does the minimum operations required, i.e.
programming the new src/dst addresses and transfer size.

TCP context is now created with refcount of 2, signifying that it's
jointly owned by an app and stack. Thus, net_context_put()
unconditionally calls net_context_unref() to decrement refcount on
app's behalf, and leaves stack's refcount to internal routines
which handle sending/receiving/timing out FINs, etc.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
TCP context is effectively owned by both application and the stack:
stack may detect that peer closed/aborted connection, but it must
not dispose of the context behind the application back. Likewise,
when application "closes" context, it's not disposed of immediately,
there's yet closing handshake for stack to perform.
This effectively means that TCP contexts have refcount of 2 when
they're created. Without this change, following situation is
possible: peer opens connection, an app get a context (or socket)
via accept, peer sends data, closes connection. An app still holds
a reference to connection, but stack may dispose of context, and
even reuse it for a new connection. Then application holds a reference
to either free, or completely different context.
This situation was very clearly and 100% reproducible when making
Zephyr port of open62541 library, which works in async manner using
select().

Most CPUs have instructions like LOCK, LDREX/STREX, etc which
allows for atomic operations without locking interrupts that
can be invoked from user mode without complication. They typically
use compiler builtin atomic operations, or custom assembly
to implement them.
However, some CPUs may lack these kinds of instructions, such
as Cortex-M0 or some ARC. They use these C-based atomic
operation implementations instead. Unfortunately these require
grabbing a spinlock to ensure proper concurrency with other
threads and ISRs. Hence, they will trigger an exception when
called from user mode.
For these platforms, which support user mode but not atomic
operation instructions, the atomic API has been exposed as
system calls.
Some of the implementations in atomic_c.c which can be instead
expressed in terms of other atomic operations have been removed.
The kernel test of atomic operations now runs in user mode to
prove that this works.
