For obvious performance reasons, scheduler state changes (other than
aborting a thread) do not cause synchronous interrupts on the other
CPU. Doing a k_thread_wakeup() means that the current CPU will run it
synchronously if it's high priority, but if you want to see it run on
the other cores you need to wait for them to reach a scheduling point
on their own.
The test was written to assume that k_thread_wakeup() is synchronous,
but that's not right, and it needs to spin a bit. This bug was always
present in the test, but masked by a bug in the way that k_sleep() was
handled on SMP. See #9506.

A few more test cases that are measurably unreliable when run in SMP.
For the most part these work most of the time (though the semaphore
one was pretty borderline -- I measured about 25% failures), but are
measurably unstable against the backdrop of known qemu instability.
Something is clearly going on and we need to come back to these to fix
threadsafety issues.

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.

The current flash configurations for all nRF52840's in Zephyr is
VERY constrained when it comes to allowing samples any space for
storage or custom areas. It only leaves the last 4 pages of flash
for "storage".
The nRF52840 is also capable of using OpenThread which defaults
to using the last 4 pages of flash for storing OpenThread-related
network data.
This means that while using OpenThread under any configuration
designed to use mcuboot partition slots, there is no space left
over for storage of any kind.
Let's adjust the partition table to set storage at 8 pages of
flash (32k). This fixes the conflict with OpenThread and leaves
room for future use cases that may arise.

Qemu just can't handle 1000 Hz ticks. On our CI machines, CONFIG_HZ
on the host (which is the limit of timing precision for things like
idle wakeups and signal delivery, both of which qemu seems to use for
timing) is 250. When the mismatch gets this large, we start seeing
artifacts like interrupts being delivered "in the past" (i.e. code
sees a z_clock_elapsed() value of "2" ticks before getting a
z_clock_announce() call for "1").
As it happens, this test doesn't actually require timing with that
precision, it just wants "lots of context switching" to exercise the
threadsafety of the mem_pool APIs. So decrease the tick rate to the
100Hz default, but put a loop counter in the worker threads to force
them to do 10x more work, keeping the number of preemptions constant.

The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.
To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.
This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

The various tests would all do a "wait for threads to exit" step
before checking the results, but this was implemented with a simple
busy wait that turns out to need careful tuning (because there was
busy waiting in the threads).
Rather than try to synchronize this, white box the issue (it's a low
level SMP test, after all) by spinning on the thread states directly
watching for the kernel to flag them dead. The downside here is that
if the process fails for some reason we'll get a hang and a timeout
reported from sanitycheck and not a synchronous ztest assertion. But
in return, successful tests run much faster and I don't need to worry
about how to tune them for IPI latency on different platforms.

This case was predicated on a mistake. The behavior of k_wakeup() has
always been NOT to wake up threads that are "pending" on a wait queue,
only ones blocked on a timeout in k_sleep(). As written, this test
case could never pass.
(Really there's no good reason for that. It seems reasonable to me to
expect wakeup to work symmetrically, and the docs are sort of
ambiguous on the subject. But the code in k_wakeup() is clear:
threads flagged pending get an early exit and the call becomes a
noop.)

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

linker and usb files. These are
