This patch series focuses on improving the machine_kexec_mask_interrupts()
function by consolidating its implementation and optimizing its behavior to
avoid redundant interrupt masking.

Patch Summary:
[PATCH v6 1/2] Move machine_kexec_mask_interrupts() to kernel/irq/kexec.c,
               removing duplicate architecture-specific implementations.
[PATCH v6 2/2] Refine machine_kexec_mask_interrupts() to avoid re-masking
               already-masked interrupts, resolving specific warnings
               triggered in GPIO IRQ flows.

Changes between v5 and v6:
 - Change GENERIC_IRQ_KEXEC_CLEAR_VM_FORWARD to not be user selectable.

Changes between v4 and v5:
 - The function machine_kexec_mask_interrupts() has been moved
   from kernel/kexec_core.c to a new file kernel/irq/kexec.c.
 - A new configuration option, GENERIC_IRQ_KEXEC_CLEAR_VM_FORWARD, has been
   added.
 - The parameters for the machine_kexec_mask_interrupts() function have
   been defined in reverse Christmas Tree style.
 - The comment explaining the call to irq_set_irqchip_state() has been
   improved for clarity.
 - The phrase 'This patch' has been removed from the commit message.

Changes between v3 and v4:
 - Add missing <linux/irqdesc.h> and <linux/irq.h> includes.

  kexec: Consolidate machine_kexec_mask_interrupts() implementation
  kexec: Prevent redundant IRQ masking by checking state before shutdown
