locking: Further name space cleanups
Thomas Gleixner [Thu, 3 Dec 2009 19:55:53 +0000 (20:55 +0100)]
The name space hierarchy for the internal lock functions is now a bit
backwards. raw_spin* functions map to _spin* which use __spin*, while
we would like to have _raw_spin* and __raw_spin*.

_raw_spin* is already used by lock debugging, so rename those funtions
to do_raw_spin* to free up the _raw_spin* name space.

No functional change.
