At a glance these are just the inverse of each other. The one subtlety is that arch_spin_value_unlocked() takes the lock by value, rather than as a pointer, which is important for the lockref code. On the other hand arch_spin_is_locked() doesn't really care, so implement it in terms of arch_spin_value_unlocked(). Signed-off-by:
