Active/Passive from [kernel.org](https://www.kernel.org/doc/Documentation/devicetree/bindings/thermal/thermal.txt):
* Cooling device nodes
Cooling devices are nodes providing control on power dissipation. There
are essentially two ways to provide control on power dissipation. First
is by means of regulating device performance, which is known as passive
cooling. A typical passive cooling is a CPU that has dynamic voltage and
frequency scaling (DVFS), and uses lower frequencies as cooling states.
Second is by means of activating devices in order to remove
the dissipated heat, which is known as active cooling, e.g. regulating
fan speeds. In both cases, cooling devices shall have a way to determine
the state of cooling in which the device is.

Fixes bug where stm32_phyinit will succeed even when no PHY is connected. This is because there is no check that a PHY is actually communicating and returning data.

Adds support for the LSM6DSO32 IMU by STM using the uORB framework. This
only contains limited support for the I2C interface, interrupt and
polling driven measurement and standard modes of operation (high
performance ODRs). Features like interrupts besides DRDY, filtering,
gesture recognition and acting as a bus master are not implemented.
For clearing some variables corresponding with the pollfds of the felip in can_close API, we modify poll logic by binding can_reader_s and pollfd.

The `$(APPDIR)` folder is added to the `$(KERNDEPDIRS)` when
`CONFIG_BUILD_KERNEL=y`. The `depend` phase iterates over the
`$(KERNDEPDIRS)` folders and executes the `depend` recipe of these
folders (including the apps' recipes) with the `__KERNEL__` macro
defined, which prevents `system()`'s prototype from being declared.
Add support for network statistics for CAN.
It includes counters for receive, sent
and drop frames.

Add a custom note for NuttX information including magic and coredump
file data size, so when system reboots, we can check if the block device
contains valid coredump file, and save it to file system.

reason:
We aim to replace big locks with smaller ones. So we will use spin_lock_irqsave extensively to
replace enter_critical_section in the subsequent process. We imitate the implementation of Linux
by adding sched_lock to spin_lock_irqsave in order to address scenarios where sem_post occurs
within spin_lock_irqsave, which can lead to spinlock failures and deadlocks.

reason:
1 Accelerated the implementation of sched_lock, remove enter_critical_section in sched_lock and
only enter_critical_section when task scheduling is required.
2 we add sched_lock_wo_note/sched_unlock_wo_note and it does not perform instrumentation logic

This forces the bch layer to read the sector from the physical device
instead of using the cached values. It is necessary to call when the
device is updated from the different source than bch, for example
erased by the MTD ioctl command.
It also has to invalidate readahead buffer from FTL if option
CONFIG_DRVR_READAHEAD is set.

The load/compare and RMW to wait_count need protection. Using atomic
operations should resolve both issues.
NOTE:
The assumption that the user will call pthread_cond_signal /
pthread_cond_broadcast with the mutex given to pthread_cond_wait held is
simply not true. It MAY hold it, but it is not forced. Thus, using the
user space lock for protecting the wait counter as well is not valid!
The pthread_cond_signal() or pthread_cond_broadcast() functions may be called by a thread whether or not it currently owns the mutex that threads calling pthread_cond_wait() or pthread_cond_timedwait() have associated with the condition variable during their waits; however, if predictable scheduling behaviour is required, then that mutex is locked by the thread calling pthread_cond_signal() or pthread_cond_broadcast().

MM_PGSIZE for now to keep gnu-elf.ld.in unified.

* Make readv/writev implementations update struct uio
This can simplify partial result handling.
* change the error number on the overflow from EOVERFLOW to EINVAL
to match NetBSD
* add a commented out uio_offset field. I used "#if 0" here as
C comments can't nest.
* add a few helper functions
Note on uio_copyfrom/uio_copyto:
although i'm not quite happy with the "offset" functionality,
it's necessary to simplify the adaptation of some drivers like
drivers/serial/serial.c, which (ab)uses the user-supplied buffer
as a line-buffer.

This commit cleans up redundant header file includes throughout the codebase.
The changes include:
- Removing duplicate #include directives that were present in the same file
- Consolidating includes that were split across multiple lines unnecessarily
- Removing unused includes that were no longer needed
- Fixing some formatting issues with includes
The changes improve code organization and maintainability by:
- Reducing unnecessary dependencies
- Making include dependencies more explicit
- Following consistent include patterns
- Removing dead code
No functional changes are made - this is purely a code cleanup commit.
