47de5a0591 libc/minimal: fix realloc() failure case
It is said that the C17 realloc() behavior is to return the original
pointer on error and that's what is implemented here. This may be
confused with a successful realloc() and nobody else does that.

Instead, a failed realloc() should return NULL, leave the original
memory intact and set errno to ENOMEM. This is the behavior described
by all the following references:

Linux/glibc:
https://man7.org/linux/man-pages/man3/malloc.3.html

NetBSD
https://man.netbsd.org/realloc.3

Microsoft
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/realloc

PTC MKS Toolkit

Let's get in line with the most common behavior.

593997046b lib/os/heap: fix out-of-bounds usage of memcpy() in sys_heap_realloc()
The sys_heap_realloc() code falls back to allocating new memory

6055c253ee shield: cmake: using Kconfig.shield instead of looking for overlay files
Fixes: #26522

Now searching for Kconfig.shield instead of recursively looking for
overlay files.

Globbing recursively for overlay files also picks up board overlays,
which leads to errors in the shield handling, as user could wrongly
specify certain boards as shields.
Also it led to wrongly list some board as shields, as reported
in #26522.

The folder containing a Kconfig.shield is then used when looking up

cafe04558c arm: cortex_m: make lazy FP stacking enabling dynamic
Under FPU sharing mode, any thread is allowed to generate
a Floating Point context (use FP registers in FP instructions),
regardless of whether threads are pre-tagged with K_FP_REGS
option when they are created.

When building with MPU stack guard feature enabled,
a large MPU stack guard is required to catch stack
overflows, if lazy FP stacking is enabled. When lazy
FP stacking is not enabled, a default 32 byte guard is
sufficient.

If lazy stacking is enabled by default, all threads may
potentially generate FP context, so they would need to
program a large MPU guard, carved out of their reserved
stack memory.

To avoid this memory waste, we modify the behavior, and make
lazy stacking a dynamically enabled feature, implemented as
follows:
- threads that are not pre-tagged with K_FP_REGS, and have
not generated an FP context use a default MPU guard and disable
lazy stacking. As long as the threads do not have an active FP
context, they won't stack FP registers, anyway, on ISRs and
exceptions, while they will benefit from reserving a small
MPU guard size
- as soon as a thread starts using FP registers, ISR might
temporarily experience some increased ISR latency due to lazy
stacking being disabled. This will be the case until the next
context switch, where the threads that have active FP context
will be tagged with K_FP_REGS, enable lazy stacking, and
program a wide MPU guard.

The implementation is a tradeoff between performance (ISR
latency) and memory consumption.

Note that when MPU STACK GUARD feature is not enabled, lazy
FP stacking is always activated.

86c1b57103 arm: cortex_m: select by default FP sharing mode when using the FPU
For applications that make use of the FPU in cortex m,
we enforce the FPU sharing registers mode, because the
compiler, under certain optimization regimes, may use
FP instructions and create FP context in any thread,
so the unshared registers mode is not practically
supported.

In addition to that we force FPU_SHARING to depend on
MULTITHREADING, as FPU sharing mode does not make sense
outside the normal multi-threaded builds.

887e1abace kernel/timeout: Fix timeout "sooner" computation
There was an edge case in the timeout handling (exposed by, but not
strictly related to, the recent timeslice fix): the next_timeout()
computation would include time slice expiration as a clamp on the
result, but this would be invoked also on the z_set_timeout_expiry()
path which gets hooked on entry to a new thread which is needed to set
the timeout in the first place.  So if no other timer interrupt was
scheduled, it was possible to miss the first timeslice interrupt after
thread scheduling.

The explanation is much longer than the fix (use <= as the comparator
instead of <).

In practice this was only being hit in the existing test suite on
riscv miv running under renode using non-default clock rates.

what naming/number convention they'd have.

Additionally, this also exposes a few other build issues with the

On single stage linking the prebuilt target == final elf, in which case
the `logical_target_for_zephyr_elf` points directly to the prebuilt

Thus using `logical_target_for_zephyr_elf` for memusage report ensures

d19307fa45 tests: mem_protect: fix failing inheritance test under SMP
The inheritance test first creates a parent thread, and then
creates a child thread inside this parent thread. At the same
time inside the main thread, a resource pool is assigned to
the parent thread. However, when under SMP, it is possible
that the pool assignment is done between both parent/child
threads are getting pointers to the pool, due to multiple
threads are running. So when doing pool pointer comparison,
there is a mismatch between those pointers (like parent has
a null pool pointer while child is pointing to the actual
pool), and thus failing the test. So fix this by delaying
the parent from running under after pool assignment is done.

af37e9d999 tests: mem_map: fix execution test for x86_64 with coverage
When coverage is enabled on x86_64, GCC uses relative addressing
to increment the gcov counters. The generated code of the test
function assumes execution is in the same location where
the linker places the test function. This does not work with
the execution test as it copies the function into another part
of memory and tries to execute from there. When the copied
function starts to run, the instruction pointer is at the newly
copied function. So any relative addressing with regard to
the instruction pointer now is invalid. Instead of
<generated code RIP + offset> for gcov counter as it should be,
now the copied code is trying to access the counter at
<copied code RIP + offset>, which points to incorrect
memory location (and possibly invalid/non-mapped memory).
To fix this, we need to tell GCC not to use relative addressing.
This can be accomplished by telling GCC to use the large memory
model. This is only used for this test as this option increases
code size quite a bit, and should not be used in general.
