Use 1u/~1u constants for TPIDRPRW bit operations.
Avoid implicit conversion to a different underlying type (MISRA Rule 10.3).
No functional change to task pointer tagging logic.

When the system startup from the PL1 SYS mode, the initialization
of the PL2 HYP register needs to be skipped. Put the Hypervisor
initialization code together and skip it all at once.

Add default values (0x0) for ARCH_TEXT_VBASE, ARCH_DATA_VBASE, and
ARCH_HEAP_VBASE to resolve cmake configuration warnings when these
values are not explicitly set during initialization.

Remove restore_critical_section() call from up_switch_context() in simulator
as it is not necessary during interrupt context switching. The critical

Remove restore_critical_section() call from common_handler() in x86_64 interrupt
processing as it is not necessary during interrupt handling. The critical section
state is properly managed by the interrupt framework elsewhere.

the virtual address of the page table (PT) is saved into the page directory (PD) entry, but the PD entry should store the physical address instead

When an interrupt occurs, the hardware automatically pushes the current RIP/RSP onto the interrupt stack. During the interrupt return, the iretq instruction pops them back. The problem is that the RIP/RSP modified by the signal is stored in the XCP context, whereas iretq operates on the interrupt stack. As a result, the RIP/RSP modified by the signal does not take effect in the iretq instruction, causing the task receiving the signal to fail to jump correctly to the signal handler. This behavior appears as if the signal is lost

Move stack alignment and kernel stack macros from architecture-specific internal
headers to public include/nuttx/irq.h. Consolidates duplicate definitions across
17 architecture families, reducing code duplication while enabling common code
to access these core alignment utilities without architecture dependencies.

The SRN number in TriCore far exceeds the PN number.
Using IRQ as the PN number would result in an overflow.
Therefore, MINIMAL_VECTORTABLE is used to ensure that
the PN number does not overflow.

- up_addrenv_find_page(): Find physical page mapped to user virtual address
from address environment page directory (stub implementation for future use)
- up_addrenv_user_vaddr(): Check if virtual address is in user space by calling
arm_uservaddr(). Enables common code to query user address space boundaries
on ARMv7-A architecture.

Add else clause to advance stack pointer (x24) by SMP_STACK_SIZE when
CONFIG_STACK_COLORATION is not defined in ARM64 boot code. Ensures each
CPU's stack is properly skipped in multi-core initialization even when
stack coloration/validation is disabled, preventing stack corruption from
overlapping CPU stacks.

Expand ARCH_KERNEL_STACK configuration to support both BUILD_KERNEL and
BUILD_PROTECTED modes. Change Kconfig dependency from "depends on BUILD_KERNEL"
to "depends on BUILD_KERNEL || BUILD_PROTECTED". Update pthread_create.c to
remove redundant BUILD_KERNEL check when allocating kernel stacks with
CONFIG_ARCH_KERNEL_STACK enabled. Enables protected builds to use separate
kernel and user stacks for processes.
