cc4ffb2a54 kernel: cmake: fix k_sleep compilation error for single thread
Fix k_sleep compilation error:
[build] ... syscalls/kernel.h:135: undefined reference to `z_impl_k_sleep'
for single thread applications (CONFIG_MULTITHREADING = n).
The shed.c contains source code which must be present also

a3e5af95de kernel: Update k_sleep() and k_usleep() return values
Updates both the k_sleep() and k_usleep() return values so that if
the thread was woken up prematurely, they will return the time left
to sleep rounded up to the nearest millisecond (for k_sleep) or
microsecond (for k_usleep) instead of rounding down. This removes
ambiguity should there be a non-zero number of remaining ticks
that correlate to a time of less than 1 millisecond or 1 microsecond.

afc59112a9 device: support for mutable devices
Add support for mutable devices. Mutable devices are those which
can be modified after declaration, in-place, in kernel mode.

In order for a device to be mutable, the following must be true

  * `CONFIG_DEVICE_MUTABLE` must be y-selected
  * the Devicetree bindings for the device must include
    `mutable.yaml`
  * the Devicetree node must include the `zephyr,mutable` property

40ba4015e3 kernel: mm: only include demand_paging.h if needed
This moves including of demand_paging.h out of kernel/mm.h,
so that users of demand paging APIs must include the header

4664813a12 kernel: spinlock: Ticket spinlocks
Basic spinlock implementation is based on single
atomic variable and doesn't guarantee locking fairness
across multiple CPUs. It's even possible that single CPU
will win the contention every time which will result
in a live-lock.

Ticket spinlocks provide a FIFO order of lock aquisition
which resolves such unfairness issue at the cost of slightly
increased memory footprint.
