Gabriel Krisman Bertazi d710b1e91b wait: Return number of exclusive waiters awaken 
commit ee7dc86b6d3e3b86c2c487f713eda657850de238 upstream.

Sbitmap code will need to know how many waiters were actually woken for
its batched wakeups implementation.  Return the number of woken
exclusive waiters from __wake_up() to facilitate that.
