Chunwei Chen cdd39dd245 Use kernel provided mutex owner 
To reduce mutex footprint, we detect the existence of owner in kernel mutex,
and rely on it if it exists.

Note that before Linux 3.0, mutex owner is of type thread_info. Also note
that, in Linux 3.18, the condition for owner is changed from
CONFIG_DEBUG_MUTEXES || CONFIG_SMP to
CONFIG_DEBUG_MUTEXES || CONFIG_MUTEX_SPIN_ON_OWNER
