This is a long over due compatibility change. Way, way, way back in 2007 there was a push to remove all consumers of SPIN_LOCK_UNLOCKED. Finally, in 2011 with 2.6.39 all the consumers have been updated and SPIN_LOCK_UNLOCKED was removed. It's about time we use the new API as well, this change does exactly that. DEFINE_SPINLOCK() was available as far back as 2.6.12 so there doesn't need to be any additional autoconf-foo for this change.
