[PATCH] powerpc: Fix building of power3 config on ppc32
The spinlock_types.h merge renamed the structure for raw_spinlock_t to match ppc64. In doing so some of the spinlock macros/functions needed to be updated to match. Apparently, this seems to only be caught when building power3. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
