[patch 04/23] locking: Convert raw_spinlock to arch_spinlock

From: Thomas Gleixner
Date: Sun Dec 06 2009 - 13:07:32 EST

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.
