Yong Wu 862c3715de iommu: Switch gather->end to the inclusive end ... Currently gather->end is "unsigned long" which may be overflow in arch32 in the corner case: 0xfff00000 + 0x100000(iova + size). Although it doesn't affect the size(end - start), it affects the checking "gather->end < end" This patch changes this "end" to the real end address (end = start + size - 1). Correspondingly, update the length to "end - start + 1".
