Christoph Lameter a3ebdb6c42 IA64: Slim down __clear_bit_unlock
__clear_bit_unlock does not need to perform atomic operations on the
variable.  Avoid a cmpxchg and simply do a store with release semantics.
Add a barrier to be safe that the compiler does not do funky things.

Tony: Use intrinsic rather than inline assembler
