This patch fixes - marking I-cache clean of pages DMAed to now only done for IA64 - broken multiple inclusion in include/asm-x86_64/swiotlb.h - missing call to mark_clean in swiotlb_sync_sg() - a (perhaps only theoretical) issue in swiotlb_dma_supported() when io_tlb_end is exactly at the end of memory Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Tony Luck <tony.luck@intel.com>
