There is exactly one function being defined with TEXT_START
macro so the x86-32 __start can appear at the beginning of
text section. Since no one else is using it, better remove
TEXT_START to simplify things.

The generic version of SECTION_VAR() is adding an extra space
during expansion before second argument (e.g.
SECTION_VAR(section, variable) => ".section. variable"
instead of ".section.variable") which would result in build
error. So remove the "##" in macro to fix this, and now it
will also behave the same as SECTION_FUNC().

This is similar to Z_GENERIC_SECTION() but the resulting
section name has a period as prefix. This eases the need
to create a section name macro for both assembly and C.

The cache API currently shipped in Zephyr is assuming that the cache
controller is always on-core thus managed at the arch level. This is not
always the case because many SoCs rely on external cache controllers as
a peripheral external to the core (for example PL310 cache controller
and the L2Cxxx family). In some cases you also want a single driver to
control a whole set of cache controllers.
Rework the cache code introducing support for external cache
controllers.

Remove this intrusive tracing feature in favor of the new object tracing
using the main tracing feature in zephyr. See #33603 for the new tracing
coverage for all objects.
This will allow for support in more tools and less reliance on GDB for
tracing objects.

Adds generic trace hook macros for inserting trace hook for
function entry, exit, blocking, and object initialization
with a variable number of arguments (objects, return values,
etc.). Utilizing macro concatenation these macros produce
trace hooks of a similar format to the old trace system
with SYS_TRACING_OBJ_FUNC(k_thread, switched_in) being
turned into sys_trace_k_thread_switched_in() by the
preprocessor. Although these macros still rely on the manual
definition of each unique trace hook in tracing.h, the benefit
of not directly calling those is that we can enable/disable
trace hooks based on object type (k_thread, k_sem, etc.)
through the preprocessor while providing the ability of adding
type specific runtime trace processing similar to
SYS_TRACING_OBJ_INIT.

Avoid confusion with device runtime idle pm states and just use device
pm states.
This simplify the code a little bit and prepare the ground for having
a better definition of device pm states. Right now this code needed to
hijack two transitional states to not break the current code logic but
the goal is avoid it and have everything in one single place.

To keep compatibility between the old GPIO API implementation and a new
one introduced in the Zephyr 2.2.0 release the gpio_pin_configure()
function was accepting interrupt flags. In the new API implementation
interrupt flags are only accepted by gpio_pin_interrupt_configure()
function.
This temporary support for INT flags in gpio_pin_configure should have
been removed in the Zephyr 2.4.0 release.

This introduces bit arrays as a new data type. This is different
than sys_bitfield as it is working on raw arrays of 32-bit
data. The bit arrays encode additional data inside the struct
to avoid going beyond the declared number of bits, and also
provides locking.
