Currently we use two separate spinlocks to protect both the hash/mapping table
and the default entry. This could be considered a bit foolish because it adds
complexity without offering any real performance advantage. This patch
removes the dedicated default spinlock and protects the default entry with the
hash/mapping table spinlock.
