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...)
Erm, concertning the latter -- probably not, as I'm not seeing other FPCIB0 backplane support in the source.
Are there any other platforms requires special DMA zone?
Erm, RBHMA4[24]00 have 8259 on the backplane... And the NEC boards with the Rockhopper backplane as well...
