Mark Johnston 02fb845bbf Fix a few uses of kern_yield() in the TTM and the LinuxKPI. ... kern_yield(0) effectively causes the calling thread to be rescheduled immediately since it resets the thread's priority to the highest possible value. This can cause livelocks when the pattern "while (!trylock()) kern_yield(0);" is used since the thread holding the lock may linger on the runqueue for the CPU on which the looping thread is running.
