Will Deacon 20e260b6f4 ARM: 7632/1: spinlock: avoid exclusive accesses on unlock() path ... When unlocking a spinlock, all we need to do is increment the owner field of the lock. Since only one CPU can be performing an unlock() operation for a given lock, this doesn't need to be exclusive. This patch simplifies arch_spin_unlock to use non-exclusive accesses when updating the owner field of the lock.
