Yep!

arch/powerpc/include/asm/spu.h:605:#define MFC_DSISR_ACCESS_PUT         (1 << 25)
arch/powerpc/include/asm/reg.h:255:#define   DSISR_ISSTORE              0x02000000      /* access was a store */

and 

arch/powerpc/include/asm/spu.h:603:#define MFC_DSISR_ACCESS_DENIED              (1 << 27)
arch/powerpc/include/asm/reg.h:254:#define   DSISR_PROTFAULT    0x08000000      /* protection fault */
