<linux/spinlock.h> has havy dependencies on other header files. It trigger circular dependencies in generated headers on IA64, at least:
CC kernel/bounds.s In file included from /home/space/kas/git/public/linux/arch/ia64/include/asm/thread_info.h:9:0, from include/linux/thread_info.h:54, from include/asm-generic/preempt.h:4, from arch/ia64/include/generated/asm/preempt.h:1, from include/linux/preempt.h:18, from include/linux/spinlock.h:50, from kernel/bounds.c:14: /home/space/kas/git/public/linux/arch/ia64/include/asm/asm-offsets.h:1:35: fatal error: generated/asm-offsets.h: No such file or directory compilation terminated.
Let's replace <linux/spinlock.h> with <linux/spinlock_types.h>, it's enough to find out size of spinlock_t.
