I think the people in this thread

[KJ][PATCH]SPIN_LOCK_UNLOCKED cleanup in arch/powerpc
http://ozlabs.org/pipermail/linuxppc-dev/2007-April/034210.html

SPIN_LOCK_UNLOCKED cleanup,use DEFINE_SPINLOCK or
__SPIN_LOCK_UNLOCKED where ever appropriate.

would like you to initialize it differently.  (I think it has
to do with the lock dependancy stuff).
