We'll definitely take the RAM savings that a few #ifdefs will deliver to us. They add up. We're selling chips for embedded use cases, not just big-iron x86 systems. Other EDAC drivers have far more #ifdef lines than the single set that I'm proposing, so I don't understand why you're singling this driver out for criticism. Consider: ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_SDRAM ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_L2C ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_OCRAM ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_OCRAM ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_L2C ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_ETHERNET ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_NAND ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_DMA ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_USB ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_QSPI ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_SDMMC ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_L2C ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_OCRAM ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_ETHERNET ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_NAND ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_DMA ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_USB ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_QSPI ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_SDMMC ./altera_edac.c:#ifdef CONFIG_EDAC_ALTERA_SDRAM ./synopsys_edac.c:#ifdef CONFIG_EDAC_DEBUG ./synopsys_edac.c:#ifdef CONFIG_EDAC_DEBUG ./synopsys_edac.c:#ifdef CONFIG_EDAC_DEBUG ./synopsys_edac.c:#ifdef CONFIG_EDAC_DEBUG ./synopsys_edac.c:#ifdef CONFIG_EDAC_DEBUG - Paul
