The previous commit erroneously noted that the !IORDY filter was turned on. No true, that change was split out into this commit. Originally authored and signed-off-by Alan Cox. Signed-off-by:Jeff Garzik <jeff@garzik.org>

With Tejun having added adev->ap some time ago we can get rid of the almost unused port being passed to mode filters. And while we are doing filters, lets turn on the !IORDY filter as well. Signed-off-by:

Now that we have ata_do_set_mode() available for drivers to use we don't actually need ->post_set_mode() as the driver can wrap set_mode nicely and do stuff before or after (eg PCMCIA needs before), so we can kill off a method in all the structs While I was at it I added kernel-doc to the function involved.

This alone isn't sufficient to save the universe from prehistoric disks and controllers but it is a first important step. Split off a separate function to provide a mode filter when controller iordy is not available. Signed-off-by:

This splits set_mode into do_set_mode and the wrapper so that a driver can call the standard method inside its own. This in theory also obsoletes ->post_set_mode(). Signed-off-by:

We end up shifting a few bits of logic around in this driver but the basic change is the same. Signed-off-by:

This changeset revolves around the fact that all the SiS controllers have the same enable bits, but differing cable detection methods. Previously that meant each type had its own error_handler methods. Instead we can now implement different ->cable_detect methods and share a single error_handler which does the filtering by enable bits. In addition we had some auto const arrays that should be static const. I'm not sure if gcc already treats them intelligently but adding the static will make sure. Signed-off-by:

There are two changes here. Firstly we switch to a cable detect method, secondly the old code forgot to call ata_std_prereset() but somehow managed to work anyway. Fix the missing call. Signed-off-by:

2.6.21-rc has horrible problems with libata and PATA cable types (and thus speeds). This occurs because Tejun fixed a pile of other bugs and we now do cable detect enforcement for drive side detection properly. Unfortunately we don't do the process around cable detection right. Tejun identified the problem and pointed to the right Annex in the spec, this patch implements the rest of the needed changes. We add a ->cable_detect() method called after the identify sequence which allows a host to do host side detection at this point should it wish, or to modify the results of the drive side identify. This separate ->cable_detect method also cleans up a lot of code because many drivers have their own error_handler methods which really just set the cable type. If there is no ->cable_detect method the cable type is left alone so a driver setting it earlier (eg because it has the SATA flags set or because it uses the old error_handler approach) will still do the right thing (or at least the same thing) as before. This patch simply adds the cable_detect method and helpers it doesn't use them but other follow up patches will (ie Adrian please don't submit patches to unexport them ;)) Signed-off-by:

Resending, with s/printk/DPRINTK/ as pointed out by Alan. Fix libata to perform CDB len validation per device rather than per host. This way, validation still works when we have a mix of 12-byte and 16-byte devices on a common host interface. Signed-off-by:

It used to be impossible to get from ata_device to ata_port but that is no longer true. Various methods have been cleaned up over time but dev_config still takes both and most users don't need both anyway. Tidy this one up Signed-off-by:

The chips covered by sata_mv have a 32-bit DMA boundary they must not cross, not a 64K boundary. We are merely limited to a 64K maximum segment size. Therefore, the DMA scatter/gather table fill code can be greatly simplified, and we need not cut in half the S/G table size as reported to the SCSI layer. Also, the driver forget to turn on 64-bit DMA at the PCI layer. All other data structures (both hardware and software) have been prepped for 64-bit PCI DMA. It was simply never turned on. <fingers crossed> let's see if it still works... Signed-off-by: -

* 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6: sis900: Allocate rx replacement buffer before rx operation usb-net/pegasus: simplify carrier detection
-
Neil Horman authored
Just found a hole in my last patch. It was reported to me that shortly after we integrated this patch. The report was of an oops that took place inside of netif_rx when using the sis900 driver. Looking at my origional patch I noted that there was a spot between the new skb_alloc and the refill_rx_ring label where skb got reassigned to the pointer currently held in the rx_ring for the purposes of receiveing the frame. The result of this is however that the buffer that gets passed to netif_rx (if it is called), then gets placed right back into the rx_ring. So if you receive frames fast enough the skb being processed by the network stack can get corrupted. The reporter is testing out the fix I've written for this below (I'm not near my hardware at the moment to test myself), but I wanted to post it for review ASAP. I'll post test results when I hear them, but I think this is a pretty straightforward fix. It just uses a separate pointer to do the rx operation, so that we don't improperly reassign the pointer that we use to refill the rx ring. Signed-off-by:
