The
Andrew Morton:
o rwsem: Make rwsems use interrupt disabling spinlocks
change in 2.4.31-pre1 has a typo: one occurrence of spin_unlock() was
changed to spin_unlock_restore() instead of spin_unlock_irqrestore()
as was obviously the intention. Since spin_unlock_restore() doesn't
exist, this results in linkage errors on x86_64 and other archs using
CONFIG_RWSEM_GENERIC_SPINLOCK.
Trival fix below.
