SPIN_LOCK_UNLOCKED doesn't work any more since v2.6.39-rc1~511^2~11 (locking: Remove deprecated lock initializers). DEFINE_SPINLOCK is available since v2.6.14-rc1~223, so it should be ok to depend on that. <linux/smp_lock.h> is gone since v2.6.39-rc1~467^2. Also <asm/system.h> is gone for most architectures since v3.4-rc1~54^2. The module builds fine for Debian's 2.6.32 and 3.6 kernels with this change.
