The code (net_buf_simple_init in particular) expects the data buffer
to immediately follow the net_buf_simple struct, so it's wrong to
request any specific alignment for this buffer. In practice this
doesn't make any difference since the net_buf_simple struct itself is
4-bytes aligned and a multiple of 4 bytes, however the extra
__net_buf_align makes it look like its location in memory doesn't need
to immediately follow the net_buf_simple struct.

The dependencies in the scripts are figures, images, includes or literal
includes. Typically those dependencies are placed relative to the .rst
file that is being copied, but in some instances you might want them to
refer to an absolute path which, in fact, is relative to Sphinx's
top-level source directory. In this case, and as long as the top-level
source directory is provided, do not emit a warning.

We don't actually need spinlocks here.
For user_copy(), we are checking that the pointer/size passed in
from user mode represents an area that the thread can read or
write to. Then we do a memcpy into the kernel-side buffer,
which is used from then on. It's OK if another thread scribbles
on the buffer contents during the copy, as we have not yet
begun any examination of its contents yet.
For the z_user_string*_copy() functions, it's also possible
that another thread could scribble on the string contents,
but we do no analysis of the string other than to establish
a length. We just need to ensure that when these functions
exit, the copied string is NULL terminated.
For SMP, the spinlocks are removed as they will not prevent a
thread running on another CPU from changing the buffer/string
contents, we just need to safely deal with that possibility.
For UP, the locks do prevent another thread from stepping
in, but it's better to just safely deal with it rather than
affect the interrupt latency of the system.

The Harness handlers for tests were parsing the realtime stream out of
qemu pipes by recompiling and executing every regex for every line (!)
of output from the simulator. That's a significant CPU load, and it's
(1) in a separate thread not tracked by the JOBS limit and (2)
happening at the worst possible time and contending with the qemu
process for host CPU cycles that it needs to hit its (real world)
timer targets on time.
Compile them just once, please.

Same deal as in commit 4638652214 ("Kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), fixing new stuff that got
introduced since then.
Some symbols, like ALTERA_AVALON_PIO, are only defined in
Kconfig.defconfig files, and so need the def_bool.
Motivation (from the note at the end of
guides/kconfig/index.html#common-shorthands):
For a symbol defined in multiple locations (e.g., in a Kconfig.defconfig
file in Zephyr), it is best to only give the symbol type for the "base"
definition of the symbol, and to use 'default' (instead of 'def_<type>'
value) for the remaining definitions. That way, if the base definition
of the symbol is removed, the symbol ends up without a type, which
generates a warning that points to the other definitions. That makes the
extra definitions easier to discover and remove.
