<asm/mach-generic/spaces.h> defines:

#ifndef CAC_BASE
#ifdef CONFIG_DMA_NONCOHERENT
#define CAC_BASE                _AC(0x9800000000000000, UL)
#else
#define CAC_BASE                _AC(0xa800000000000000, UL)
#endif
#endif

No 0x9000000000000000 anywhere - and it would be wrong because it stands
for uncached.
