Prettify the CONFIG_DEBUG_SPINLOCK __SPIN_LOCK_UNLOCKED initializers.
Clean up some warnings with CONFIG_DEBUG_SPINLOCK enabled.
Fix build with spinlock debugging turned on. Patch is cleaner like this,
too.
Remove mandatory 16-byte alignment requirement on PA2.0 processors by
using the ldcw,CO completer. Provides a nice insn savings.
