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.

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.

If CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT is enabled,
the app shared memory partition may cause waste of memory
due to the need for padding.
For example, tests/subsys/jwt and board mps2_an385:
z_test_mem_partition: addr 0x20000000, size 52
z_libc_partition : addr 0x20000040, size 4
k_mbedtls_partition : addr 0x20008000, size 32736
ending at 0x2000ffff, taking up 65536 bytes
With power-of-two size and alignment requirement,
k_mbedtls_partition takes up 32KB memory and needs to be
aligned on 32KB boundary. If the above partitions are
ordered as shown, there needs to be a lot of padding
after z_libc_partition before k_mbedtls_partition can
start. In order to minimize padding, these partitions
need to be sort by size in descending order.
After the changes here, the partitions are:
k_mbedtls_partition : addr 0x20000000, size 32736
z_test_mem_partition: addr 0x20008000, size 52
z_libc_partition : addr 0x20008040, size 4
ending at 0x2000805f, taking up 32864 bytes

There was a detected user error in the code where racing insertions of
k_delayed_work items into different queues would be detected and
flagged as an error (honestly I don't see much value there -- Zephyr
doesn't as a general rule protect against errors like this, and
work_q's are inherently kernel things that don't require
userspace-style checking).
This got broken with spinlockification, where each work_q object got
its own lock, so the single lock wouldn't protect against the other
insert function any more. As it happens, that was needless. The core
synchronization on a work_q is in the internal k_queue object anyway
-- the lock in this file was only ever used for (very fast,
noncontending) delayed work insertion. So go back to a global lock to
preserve the original behavior.

MISRA rules (see #9892) forbid alloca() and family, even though those
features can be valuable performance and memory size optimizations
useful to Zephyr.
Introduce a MISRA_SANE kconfig, which when true enables a gcc error
condition whenever a variable length array is used.
When enabled, the mempool code will use a theoretical-maximum array
size on the stack instead of one tailored to the current pool
configuration.
The rbtree code will do similarly, but because the theoretical maximum
is quite a bit larger (236 bytes on 32 bit platforms) the array is
placed into struct rbtree instead so it can live in static data (and
also so I don't have to go and retune all the test stack sizes!).
Current code only uses at most two of these (one in the scheduler when
SCHED_SCALABLE is selected, and one for dynamic kernel objects when
USERSPACE and DYNAMIC_OBJECTS are set).
This tunable is false by default, but is selected in a single test (a
subcase of tests/kernel/common) for coverage. Note that the I2C and
SPI subsystems contain uncorrected VLAs, so a few platforms need to be

With newer newlib we get a build error with mqueue.h realted to mode_t.
Let's just let newlib define mode_t and have minimal libc also define
it in sys/types.h. So we remove the duplicated definition in
posix/unistd.h.
