Commit da4561bd9c6b ("arm64, scs: save scs_sp values per-cpu when switching stacks") of -mm is moving declaration of irq_shadow_call_stack_ptr to scs.h of arm64 for !SHADOW_CALL_STACK, but didn't include it in irq.c of arm64. As a result, we show below build error when SHADOW_CALL_STACK is unset. linux/arch/arm64/kernel/irq.c: In function 'init_irq_scs': linux/arch/arm64/kernel/irq.c:44:11: error: 'irq_shadow_call_stack_ptr' undeclared (first use in this function) 44 | per_cpu(irq_shadow_call_stack_ptr, cpu) = | ^~~~~~~~~~~~~~~~~~~~~~~~~ This commit fixes the build error by including the header file.
