Some ZONE_DMA patches were merged in 2.6.21.  On most MIPS, ZONE_DMA
is not needed, isn't it?

Currently JAZZ, MALTA, QEMU, IP22, SNI_RM, RBTX4938 defines
GENERIC_ISA_DMA so they may need ZONE_DMA (though I wonder QEMU or
RBTX4938 really need it...)

Are there any other platforms requires special DMA zone?
