Patch Summary: [PATCH v3 1/2] Move machine_kexec_mask_interrupts() to kexec_core.c, removing duplicate architecture-specific implementations. [PATCH v3 2/2] Refine machine_kexec_mask_interrupts() to avoid re-masking already-masked interrupts, resolving specific warnings triggered in GPIO IRQ flows.
