/*
* Simple spin lock operations. There are two variants, one clears IRQ's
* on the local processor, one does not.
There is no agreed-upon definition of spin_unlock_wait()'s semantics, and it appears that all callers could do just as well with a lock/unlock pair. This commit therefore removes the underlying arch-specific arch_spin_unlock_wait(). Signed-off-by: Paul E.
