This patchset removes useless ISA_DMA_THRESHOLD: - ISA_DMA_THRESHOLD is irrelevant to the majority of architectures but they have to define it. - ISA_DMA_THRESHOLD definition is inconsistent on architectures; ISA DMA addressing restriction, DMA addressing restriction or something else. - Everyone (except for SCSI) uses dma_mask instead of ancient ISA_DMA_THRESHOLD. Only SCSI uses ISA_DMA_THRESHOLD for ancient drivers with non-zero unchecked_isa_dma. We can safely remove ISA_DMA_THRESHOLD usage in SCSI. So we can clean up ISA_DMA_THRESHOLD on the whole tree. = arch/alpha/include/asm/scatterlist.h | 2 -- arch/avr32/include/asm/scatterlist.h | 2 -- arch/blackfin/include/asm/scatterlist.h | 2 -- arch/cris/include/asm/scatterlist.h | 2 -- arch/frv/include/asm/scatterlist.h | 2 -- arch/h8300/include/asm/scatterlist.h | 2 -- arch/ia64/include/asm/scatterlist.h | 9 --------- arch/m32r/include/asm/scatterlist.h | 2 -- arch/m68k/include/asm/scatterlist.h | 3 --- arch/microblaze/include/asm/scatterlist.h | 2 -- arch/mips/include/asm/scatterlist.h | 2 -- arch/mn10300/include/asm/scatterlist.h | 2 -- arch/parisc/include/asm/scatterlist.h | 1 - arch/powerpc/include/asm/scatterlist.h | 3 --- arch/s390/include/asm/scatterlist.h | 2 -- arch/score/include/asm/scatterlist.h | 2 -- arch/sh/include/asm/scatterlist.h | 2 -- arch/sparc/include/asm/scatterlist.h | 1 - arch/x86/include/asm/scatterlist.h | 1 - arch/xtensa/include/asm/scatterlist.h | 2 -- drivers/scsi/aha1542.c | 9 --------- include/linux/blkdev.h | 2 +- 22 files changed, 1 insertions(+), 56 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
