locking: Convert raw_spinlock to arch_spinlock
Thomas Gleixner [Wed, 2 Dec 2009 18:49:50 +0000 (19:49 +0100)]
The raw_spin* namespace was taken by lockdep for the architecture
specific implementations. raw_spin_* would be the ideal name space for
the spinlocks which are not converted to sleeping locks in preempt-rt.

Linus suggested to convert the raw_ to arch_ locks and cleanup the
name space instead of using an artifical name like core_spin,
atomic_spin or whatever

No functional change.
