ARM: 8101/1: mach-iop13xx: fix possible build failure
After applying patch: "ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size" following build failure happens on iop13xx platform: In file included from include/linux/srcu.h:33:0, from include/linux/notifier.h:15, from include/linux/reboot.h:5, from arch/arm/mach-iop13xx/include/mach/iop13xx.h:6, from arch/arm/mach-iop13xx/include/mach/hardware.h:14, from arch/arm/mach-iop13xx/include/mach/memory.h:4, from arch/arm/include/asm/memory.h:24, from arch/arm/include/asm/page.h:163, from arch/arm/include/asm/thread_info.h:17, from include/linux/thread_info.h:54, from include/asm-generic/preempt.h:4, from arch/arm/include/generated/asm/preempt.h:1, from include/linux/preempt.h:18, from include/linux/spinlock.h:50, from include/linux/seqlock.h:35, from include/linux/time.h:5, from include/uapi/linux/timex.h:56, from include/linux/timex.h:56, from include/linux/sched.h:19, from arch/arm/kernel/asm-offsets.c:13: include/linux/rcupdate.h: In function '__rcu_read_lock': >> include/linux/rcupdate.h:220:2: error: implicit declaration of function 'preempt_disable' [-Werror=implicit-function-declaration] preempt_disable(); The problem here is recursive header inclusion which could be avoided by removing linux/reboot.h from mach/iop13xxx.h. linux/reboot.h in include/mach/iop13xx.h is needed only for enum reboot_mode, so header it could be replaced with a enum declaration. Whatever patch "ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size" does, I think it's good to avoid unnecessary header inclusion here in any case.
