Disabling SMP mode for certain tests was a one-release thing, done to avoid having to triage every test independently (MANY are not SMP-safe), and with the knowledge that it was probably hiding bugs in the kernel. Turn it on pervasively. Tests are treated with a combination of flagging specific cases as "1cpu" where we have short-running tests that can be independently run in an otherwise SMP environment, and via setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still runs the full SMP kernel config, but with only one CPU available).

Synchronization using CMSI RTOS V1 APIs
#######################################
Overview
********
The sample project illustrates usage of timers and message queues using
CMSIS RTOS V1 APIs.
The main thread creates a preemptive thread which writes message to message queue
and on timer expiry, message is read by main thread.
Building and Running Project
****************************
This project outputs to the console. It can be built and executed
on QEMU as follows:
.. zephyr-app-commands::
:zephyr-app: samples/philosophers
:host-os: unix
:board: qemu_x86
:goals: run
