lockdep: Selftest: convert spinlock to raw spinlock
Yong Zhang [Mon, 16 Apr 2012 07:01:55 +0000 (15:01 +0800)]
To make the lockdep selftest working on RT we need to convert the
spinlock tests to a raw spinlock. Otherwise we cannot run the irq
context checks. For mainline this is just annotational as spinlocks
are mapped to raw_spinlocks anyway.
