2008-01-23libata: convert to chained sgTejun Heo1-1/+3
libata used private sg iterator to handle padding sg. Now that sg can be chained, padding can be handled using standard sg ops. Convert to chained sg. * s/qc->__sg/qc->sg/ * s/qc->pad_sgent/qc->extra_sg[]/. Because chaining consumes one sg entry. There need to be two extra sg entries. The renaming is also for future addition of other extra sg entries. * Padding setup is moved into ata_sg_setup_extra() which is organized in a way that future addition of other extra sg entries is easy. * qc->orig_n_elem is unused and removed. * qc->n_elem now contains the number of sg entries that LLDs should map. qc->mapped_n_elem is added to carry the original number of mapped sgs for unmapping. * The last sg of the original sg list is used to chain to extra sg list. The original last sg is pointed to by qc->last_sg and the content is stored in qc->saved_last_sg. It's restored during ata_sg_clean(). * All sg walking code has been updated. Unnecessary assertions and checks for conditions the core layer already guarantees are removed.

Implement protocol tests - ata_is_atapi(), ata_is_nodata(), ata_is_pio(), ata_is_dma(), ata_is_ncq() and ata_is_data() and use them to replace is_atapi_taskfile() and hard coded protocol tests. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-11-03ata/sata_fsl: Remove unnecessary SCR casesJeff Garzik1-14/+2
SCRs in the driver map to the standard values found in include/linux/ata.h, so no need for individual scr_read/scr_write case statements duplicating the natural value.
