Some code manually calls local_bh_disable() and spin_lock() but
then calls spin_unlock_bh() (or vice versa).
Our code then calls local_bh_disable() again from spin_lock()
which means we have the thread pin count increased twice and that
means we get out of synch and are still pinned when returning to
user space.
Avoid this by adding the explicit local_bh_{enable,disable}() to
the spin_[un]lock_bh() versions.
