- * qla2x00_normalize_dma_addr() - Normalize an DMA address.
- * @e_addr: Raw DMA address
- * @e_len: Raw DMA length
- * @ne_addr: Normalized second DMA address
- * @ne_len: Normalized second DMA length
- *
- * If the address does not span a 4GB page boundary, the contents of @ne_addr
- * and @ne_len are undefined.  @e_len is updated to reflect a normalization.
- *
- * Example:
- *
- * 	ffffabc0ffffeeee	(e_addr) start of DMA address
- * 	0000000020000000	(e_len)  length of DMA transfer
- *	ffffabc11fffeeed	end of DMA transfer
- *
- * Is the 4GB boundary crossed?
- *
- * 	ffffabc0ffffeeee	(e_addr)
- *	ffffabc11fffeeed	(e_addr + e_len - 1)
- *	00000001e0000003	((e_addr ^ (e_addr + e_len - 1))
- *	0000000100000000	((e_addr ^ (e_addr + e_len - 1)) & ~(0xffffffff)
- *
- * Compute start of second DMA segment:
- *
- * 	ffffabc0ffffeeee	(e_addr)
- *	ffffabc1ffffeeee	(0x100000000 + e_addr)
- *	ffffabc100000000	(0x100000000 + e_addr) & ~(0xffffffff)
- *	ffffabc100000000	(ne_addr)
- *
- * Compute length of second DMA segment:
- *
- *	00000000ffffeeee	(e_addr & 0xffffffff)
- *	0000000000001112	(0x100000000 - (e_addr & 0xffffffff))
- *	000000001fffeeee	(e_len - (0x100000000 - (e_addr & 0xffffffff))
- *	000000001fffeeee	(ne_len)
- *
- * Adjust length of first DMA segment
- *
- * 	0000000020000000	(e_len)
- *	0000000000001112	(e_len - ne_len)
- *	0000000000001112	(e_len)
- *
- * Returns non-zero if the specified address was normalized, else zero.
