Please introduce the futex_type magic and the related changes to the pi
code in a seperate patch so it can be verified independently.
It's sad

This patch introduces a new futex implementation called
throughput-optimized (TO) futexes. The goal of this new futex type is
to provide locking throughput that is higher than wait-wake futexes
especially on systems with a large number of CPUs and the lock owners
are unlikely to sleep. The
