7dc3ecd63d stdint.h: Make {u}int64_t types consistent regardless of arch
On 64-bit arch's like AARCH64, x86_64, or riscv-64 the way {u}int64_t
will differ from how its defined on 32-bit arch's.  Do the same trick we
do for {u}int32_t for {u}int64_t so that the type is the same regardless
of what we are building for.

This keeps things like %lld working the same regardless of 32-bit or
64-bit arch.

be919d3bf7 userspace: improve dynamic object allocation
We now have a low-level function z_dynamic_object_create()
which is not a system call and is used for installing
kernel objects that are not supported by k_object_alloc().

Checking for valid object type enumeration values moved
completely to the implementation function.

A few debug messages and comments were improved.

Futexes and sys_mutexes are now properly excluded from
dynamic generation.

378024c510 userspace: add z_is_in_user_syscall()
Certain types of system call validation may need to be pushed
deeper in the implementation and not performed in the verification
function. If such checks are only pertinent when the caller was
from user mode, we need an API to detect this situation.

This is implemented by having thread->syscall_frame be non-NULL
only while a user system call is in progress. The template for the
system call marshalling functions is changed to clear this value
on exit.

A test is added to prove that this works.

99c2d2d047 kernel/queue: Remove interior use of k_poll()
The k_queue data structure, when CONFIG_POLL was enabled, would
inexplicably use k_poll() as its blocking mechanism instead of the
original wait_q/pend() code.  This was actually racy, see commit
b173e4353f.  The code was structured as a condition variable: using
a spinlock around the queue data before deciding to block.  But unlike
pend_current_thread(), k_poll() cannot atomically release a lock.

A workaround had been in place for this, and then accidentally
reverted (both by me!) because the code looked "wrong".

This is just fragile, there's no reason to have two implementations of
k_queue_get().  Remove.

Note that this also removes a test case in the work_queue test where
(when CONFIG_POLL was enabled, but not otherwise) it was checking for
the ability to immediately cancel a delayed work item that was
submitted with a timeout of K_NO_WAIT (i.e. "queue it immediately").
This DOES NOT work with the origina/non-poll queue backend, and has
never been a documented behavior of k_delayed_work_submit_to_queue()
under any circumstances.  I don't know why we were testing this.

Fixes #25904

6e8775ff84 devicetree: remove DT_HAS_NODE_STATUS_OKAY
Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:

- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
  for macros which are equivalent to
  DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name

Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.

hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

d27f6cb5eb interrupt_controller: program local APIC LDR register for xAPIC
If IO APIC is in logical destination mode, local APICs compare their
logical APIC ID defined in LDR (Logical Destination Register) with
the destination code sent with the interrupt to determine whether or not
to accept the incoming interrupt.

This patch programs LDR in xAPIC mode to support IO APIC logical mode.

The local APIC ID from local APIC ID register can't be used as the
'logical APIC ID' because LAPIC ID may not be consecutive numbers hence
it makes it impossible for LDR to encode 8 IDs within 8 bits.

This patch chooses 0 for BSP, and for APs, cpu_number which is the index
to x86_cpuboot[], which ultimately assigned in z_smp_init[].

7e0eed9235 devicetree: allow access to all nodes
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is

Sometimes we want to operate on special nodes without matching

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY

- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API

8d7bb8ffd8 device: Refactor device structures
When the device driver model got introduced, there were no concept of
SYS_INIT() which can be seen as software service. These were introduced
afterwards and reusing the device infrastructure for simplicity.
However, it meant to allocate a bit too much for something that only
required an initialization function to be called at right time.

Thus refactoring the devices structures relevantly:
- introducing struct init_entry which is a generic init end-point
- struct deviceconfig is removed and struct device owns everything now.
- SYS_INIT() generates only a struct init_entry via calling
  INIT_ENTRY_DEFINE()
- DEVICE_AND_API_INIT() generates a struct device and calls
  INIT_ENTRY_DEFINE()
- init objects sections are in ROM
- device objects sections are in RAM (but will end up in ROM once they
  will be 'constified')

87e1743ae0 devicetree: replace DT_HAS_DRV_INST with DT_INST_FOREACH
Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.

There are a few exceptions:

- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
  would require more time to convert than I have at the moment. For the
  sake of expediency, just inline the DT_HAS_DRV_INST expansion for
  now in these cases.

- SoC drivers which are explicitly single-instance (like the nRF SAADC
  driver). Again for the sake of expediency, drop a BUILD_ASSERT in
  those cases to make sure the assumption that all supported SoCs have
  at most one available instance is valid, failing fast otherwise.

78a6cdb07c Bluetooth: host: Avoid use of array compound literals in API
Attempt to fix C++ error: taking address of temporary array.

According to GCC documentation:
  In C++, a compound literal designates a temporary object that only
  lives until the end of its full-expression.

Finishing with this recommendation:
  As an optimization, G++ sometimes gives array compound literals
  longer lifetimes: when the array either appears outside a function
  or has a const-qualified type.
  But it is probably safest just to avoid the use of array compound
  literals in C++ code.

Fix the issue by introducing INIT macros as an alternative, and use
these in the inline functions to avoid the use of array compound
literals in Bluetooth headers.

8b27d5c6b9 linker: Clean up section name definitions
This commit cleans up the section name definitions in the linker
sections header file (`include/linker/sections.h`) to have the uniform
format of `_(SECTION)_SECTION_NAME`.

In addition, the scope of the short section reference aliases (e.g.
`TEXT`, `DATA`, `BSS`) are now limited to the ASM code, as they are
currently used (and intended to be used) only by the ASM code to
specify the target section for functions and variables, and these short
names can cause name conflicts with the symbols used in the C code.

ca872a44c1 lib: posix: Add support for eventfd
This implements a file descriptor used for event notification that
behaves like the eventfd in Linux.

The eventfd supports nonblocking operation by setting the EFD_NONBLOCK
flag and semaphore operation by settings the EFD_SEMAPHORE flag.

The major use case for this is when using poll() and the sockets that
you poll are dynamic. When a new socket needs to be added to the poll,
there must be some way to wake the thread and update the pollfds before
calling poll again. One way to solve it is to have a timeout set in the
poll call and only update the pollfds during a timeout but that is not
a very nice solution. By instead including an eventfd in the pollfds,
it is possible to wake the polling thread by simply writing to the
eventfd.

df152ab59f net: coap: Add initial tx time to coap_pending structure
So far, coap_pending structure kept track only of the timeout interval
between two consecutive retransmissions. Calculations inside
`coap_pending_next_to_expire` relied only on this value. This approach
gives incorrect results though, in case multiple messages are pending
for retransmission.

For instance, assuming initial retransmission timeout is set to 2
seconds. If some message had been retransmitted already, its timeout
would be increased to 4 seconds. Any new message added to the pending
list would have a retransmission timeout set to 2 seconds, and will be
returned as a first message to expire, no matter how long the initial
message was already on the list.

To resolve this, add a `t0` field to the coap_pending structure. This
field is initialized to the initial transmission time, and is increased
on each retransmission by the retransmission timeout.
`coap_pending_next_to_expire` uses this value to calculate absolute
time, when the next retransmission should take place, and based on this
information returns correctly first pending message to expire.

0e6ede8929 kconfig: Rename CONFIG_FLOAT to CONFIG_FPU
This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).

Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.
