[PATCH RFC 21/26] powerpc: Remove spin_unlock_wait() arch-specific definitions

2017-06-29 Thread Paul E. McKenney
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. McKenney
