Previously, some links were not resolving properly since they
lacked the :ref: prefix, so it was added.

POSIX Subprofiles
=================
While Zephyr supports running multiple `threads <threads_v2>` (possibly in an `SMP <smp_arch>`
configuration), as well as `Virtual Memory and MMUs <memory_management_api>`, Zephyr code and data
normally share a common address space. The Zephyr kernel executable code and the application
executable code are typically compiled into the same binary artifact. From that perspective, Zephyr
apps can be seen as running in the context of a single process.

Systems (RTOS) such as Zephyr typically serve a fixed-purpose, have limited hardware resources,
