Subject: kernel/bounds: avoid circular dependencies in generated headers
<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 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 kernel/bounds.c:14:
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.
