This commit enables the CMSIS-Core(R) processor interface driver for
the Cortex-R platforms by default.
The CMSIS-Core component provides a set of standard interface functions
to control the Cortex-R series processor cores and will be required by
the arch port as well as other CMSIS library components (e.g. CMSIS-DSP
and CMSIS-NN).

How prompts work is better documented nowadays, and these comments might
not be that helpful if you don't know.
There are lots promptless symbols that don't have a comment.
Also fix up some comments in arch/Kconfig that seem misplaced/redundant,
and clean up some whitespace (no blank line after a comment makes it
look like it only applies to the symbol directly after it to me).

Out-of-tree code can still be using the old file locations. Introduce
header shims to include the headers from the new correct location and

Add also a new Kconfig symbol to suppress such warning.
The shim will go away after two releases, so make sure to adapt your

This is causing problems, as if we create a thread in
a system call we will *not* be using the kernel page
tables if CONFIG_KPTI=n, resulting in a crash when
the later call to copy_page_tables() tries to initialize
the PDPT (which is in the same page as the privilege
stack).
Just don't fiddle with this page's permissions; we don't
need it as a guard area anyway since we have a stack
guard placed immediately before it, and this page
is unused if user mode isn't active.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Also replace some
config
prompt "foo"
bool/int
with the more common shorthand
config
bool/int "foo"

This commit inlines arch_isr_direct_header function that was previously
placed in irq_manage.c for no good reason (possibly in relation to the
FIXME for #3056).
In addition, since the PR #20119 resolved the header circular
dependency issue described in the issue #3056, this commit removes the
references to it in the code.
The reason for not inlining _arch_is_direct_pm as the #3056 FIXME
suggests is that there is little to gain from doing so and there still
exists circular dependency for the headers required by this function
(#20119 only addresses kernel_structs.h, which is required for _current
and _kernel, which, in turn, is required for handling interrupt nesting
in many architectures; in fact, Cortex-A and Cortex-R port will require
it as well).

We introduce MPU_GAP_FILLING Kconfig option that instructs
the MPU driver to enforce a full SRAM partitioning, when it
programs the dynamic MPU regions (user thread stack, PRIV stack
guard and application memory domains) at context-switch. We
allow this to be configurable, in order to increase the number
of MPU regions available for application memory domain programming.
This option is introduced in arch/Kconfig, as it is expected
to serve as a cross-ARCH symbol. The option can be set by the
user during build configuration.
By not enforcing full partition, we may leave part of kernel
SRAM area covered only by the default ARM memory map. This
is fine for User Mode, since the background ARM map does not
allow nPRIV access at all. The difference is that kernel code
will be able to attempt fetching instructions from kernel SRAM
area without this leading directly to a MemManage exception.
Since this does not compromize User Mode, we make the skipping
of full partitioning the default behavior for the ARMv8-M MPU
driver. The application developer may be able to overwrite this.
In the wake of this change we update the macro definitions in
arm_core_mpu_dev.h that derive the maximum number of MPU regions
for application memory domains.
