Torvald Riegel 4eb984d3ab Clean up BUSY_WAIT_NOP and atomic_delay. ... This patch combines BUSY_WAIT_NOP and atomic_delay into a new atomic_spin_nop function and adjusts all clients. The new function is put into atomic.h because what is best done in a spin loop is architecture-specific, and atomics must be used for spinning. The function name is meant to tell users that this has no effect on synchronization semantics but is a performance aid for spinning.		2015-06-30 15:57:15 +02:00
