Multiple links and different number of devices per link should be considered to iterate over links and devices. This patch implements and uses link and device iterators - ata_port_for_each_link() and ata_link_for_each_dev() - and ata_link_max_devices(). This change makes a lot of functions iterate over only possible devices instead of from dev 0 to dev ATA_MAX_DEVICES. All such changes have been examined and nothing should be broken. While at it, add a separating comment before device helpers to distinguish them better from link helpers and others.

Introduce ata_link. It abstracts PHY and sits between ata_port and ata_device. This new level of abstraction is necessary to support SATA Port Multiplier, which basically adds a bunch of links (PHYs) to a ATA host port. Fields related to command execution, spd_limit and EH are per-link and thus moved to ata_link. This patch only defines the host link. Multiple link handling will be added later. Also, a lot of ap->link derefences are added but many of them will be removed as each part is converted to deal directly with ata_link instead of ata_port. This patch introduces no behavior change.

Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.

The recent mv_fill_sg() rewrite, to fix a data corruption problem related to IOMMU virtual merging, forgot to account for the potentially-increased size of the scatter/gather table after its run. Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff to more closely match the needs of mv_fill_sg().

When PCIX_IRQ_WOC is used, sil24 has an inherent race condition between clearing IRQ pending and reading IRQ status. If IRQ pending is cleared after reading IRQ status, there's possibility of lost IRQ. If IRQ pending is cleared before reading IRQ status, spurious IRQs will occur. sata_sil24 till now cleared IRQ pending after reading IRQ status thus losing IRQs on machines where PCIX_IRQ_WOC was used. Reverse the order and ignore spurious IRQs if PCIX_IRQ_WOC. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

Fix "lost" interrupt problem when using dma with CD/DVD drives in some configurations. This problem can make installing linux from media impossible for distro's that have switched to libata-only configurations. The simple fix is to eliminate the use of dma for reading drive status, etc, by checking the number of bytes to transferred. This change will only affect the behavior of atapi devices, not disks.

This patch corrects sata_promise to classify FastTrack TX4200 (DID 3515/3519) as a second-generation chip. Promise's partial- source FT TX4200 driver confirms this classification. Treating it as a first-generation chip causes several problems: 1. Detection failures. This is a recent regression triggered by the hotplug-enabling changes in 2.6.23-rc1. 2. Various "failed to resume link for reset" warnings. This patch fixes <http://bugzilla.kernel.org/show_bug.cgi?id=8936>. Thanks to Stephen Ziemba for reporting the bug and for testing the fix.

Previously I reported that the pata_pdc2027x PLL detection changes in kernel 2.6.22 broke the driver on my PowerMac: >pata_pdc2027x: Invalid PLL input clock 1691742kHz, give up! This is followed by a number of errors and speed reduction steps on the affected ports. There are two bugs in pata_pdc2027x's PLL detection code: 1. The PLL counter's start value is read before the chip is put in "test mode". Outside of test mode the counter is halted, and on the PowerMac the counter is zero because the chip hasn't been initialised by its BIOS. The fix is to move the read of the start value to after test mode is started, but before the mdelay() in test mode. This also improves the precision of the PLL detection. 2. The code to compute the number of PLL decrements during the mdelay() in test mode fails to consider that the PLL counter only is 30 bits wide. If there is a wraparound, it will compute an incorrect and much too large value. On the PowerMac, the start count is zero, the end count is a large 30-bit value, so wraparound occurs and an out of bounds PLL clock is detected. The fix is to mask the (start - end) computation to 30 bits. While debugging this I also noticed that pdc_read_counter() reads the two halves of the 30-bit PLL counter as 16-bit values, and then combines them as if the halves only are 15 bits wide. To avoid confusion, the halves should be read as 15-bit values. This patch implements all three changes. It fixes the PLL detection failure on my PowerMac, and doesn't cause any regressions on an x86 with an identical card.
