This enables qemu_x86_tiny to be used for more general demand
paging testing where non-pinned code and data is not available
in physical memory at boot. This adds a custom linker script to
qemu_x86_tiny for pinning code and data. In the process, a new
kconfig CONFIG_BOARD_QEMU_X86_TINY has to be introduced to
distinguish from other qemu_x86* boards. This linker script
is based on the generic x86-32 one in
include/arch/x86/ia32/linker.ld, with additions to
put symbols into boot and pinned sections.

mapping. This is simply to make sure the whole array
is in physical memory for mapping or else the mapping

There are quite a few symbols which are needed before the paging

For hardware stack overflow test, pin the whole stack if
demand paging is enabled and generic sections are not all present
at boot. The whole stack may not be in memory at the time of
test, which would result in double fault (exception being
handled + page fault). So make sure the stack is in physical
memory and mapped before doing any tests.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Busy check APIs now return boolean type. Due to that change, the

boolean check type APIs is "PREFIX_is_CONDITION". For example,

pm_device_is_busy and pm_device_any_busy_check to pm_device_is_any_busy.

The following device busy APIs:

were used for device PM, so they have been moved to the pm subsystem.
This means they are now prefixed with `pm_` and are defined in
`pm/device.h`.
If device PM is not enabled dummy functions are now provided that do
nothing or return `-ENOSYS`, meaning that the functionality is not

The stack array tstacks was declared in the header file using
the same macro which defines the same stack array but with
an added "extern" in front. This macro adds alignment and section
attribute which are actually not the same as the actual stack array
defined in main.c. The section name used in the section attribute
contains the file name where the stack array is defined or extern
declared. So the same symbol, in this case z_interrupt_stacks, has
different attributes in two places, and GCC 11 starts to complain
about this. So use the newly introduced macro to extern declare
the stack array without adding/replacing any symbol attributes.

Not all arch has native support for __builtin_popcount() on
hardware and GCC falls back in using software only implementation.
However, with GCC 11, this is no longer included automatically
and requires linking explicitly with libgcc.a. This is not
trivial as it requires changes some linker magic and a sizable
change to most linker scripts. So opt for an easy solution
by implementing our own popcount in the test.

We have some static variables var, zeroed_var and bss_var
in mem_partition.c and we only assert the value of them in
the same file, so the compiler may pre-calculate it in compile
stage, it's fine usually.
But for variable zeroed_var (= 20420), we force to put it in bss
section in link stage, the value will change in bss clean stage, so
we will get a wrong result.
Let's add volatile for these variables to disable pre-calculation.

In the timeout order test, the usage of k_poll() assumes that it
only returns after all events are ready. However, that is not
the case, as k_poll() returns when non-zero number of events are
ready. This means the check for all semaphore being ready after
k_poll() will not always pass. So instead of using k_poll(),
simply wait a bit for timers to fire, then check results.
Also add some bits to clean up at the end of test.

Every va_start() currently triggers a FPU access trap if FPU is not
already used. This is due to the fact that va_start() must copy FPU
registers that are used for float argument passing into the va_list
object. Flushing the FPU context to its owner and granting access to
the current thread is wasteful if this is only for va_start(),
especially since in most cases there are simply no FP arguments
being passed by the caller.
This is made even worse with exception code (syscalls, IRQ handlers,
etc.) where the exception code has to be resumed with interrupts
disabled upon FPU access as there is no provision for preserving an
interrupted exception mode's FPU context.
Fix those issues by simply simulating the sequence of STR instructions
that the va_start() generates without actually granting FPU access.
We limit ourselves only to exception context to keep changes to a
minimum for now.
This also allows for reverting the ARM64 exception in the nested IRQ
test as it now works properly even if FPU_SHARING is enabled.

This test takes an interrupt lock and tries to call z_swap_unlocked()
while holding it. That's not legal (in the general case it means
you're breaking a caller's lock!), though in this particular case it
was safe because we'll never return to this.
Regardless, there is a natural z_swap_irqlock() that releases the lock
atomically. Use that.

This test case was taking a (traditional) irq_lock(), which masks
interrupts, and then calling k_mutex_lock() with a timeout of
K_FOREVER, which is a blocking call. That's not legal, because it
will obviously schedule other threads to run in a context where the
code was promised it would not. This used to be an uncaught error,
but now we have an assertion that catches this.
It's not clear what this test case is supposed to be testing, as the
behavior is actually identical to the release_global_lock case except
for the (incorrect) addition of the irq_lock(). If this is needed for
code coverage we can work to figure out the real root cause of the
missing coverage later.
