- * 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.
