[PATCH] Directed yield: direct yield of spinlocks for powerpc
Powerpc already has a directed yield for CONFIG_PREEMPT="n". To make it work with CONFIG_PREEMPT="y" as well the _raw_{spin,read,write}_relax primitives need to be defined to call __spin_yield() for spinlocks and __rw_yield() for rw-locks.
