The only case where no MAX_DMA_CHANNELS is defined is only MIPS with CONFIG_GENERIC_ISA_DMA_SUPPORT_BROKEN. In arch/mips/include/asm/dma.h: #ifndef CONFIG_GENERIC_ISA_DMA_SUPPORT_BROKEN #define MAX_DMA_CHANNELS 8 #endif What is the intention of this ifdef? thanks, Takashi (not interested but just bored ;)
