pata_hpt366: fix cable detection,

2008-12-16T10:40:32Z

pata_hpt366 is strange in that its two channels occupy two PCI functions and both are primary channels and bit1 of PCI configuration register 0x5A indicates cable for both channels. Signed-off-by: Tejun Heo Cc: Alan Cox Cc: Sergei Shtylyov Signed-off-by: Jeff Garzik

pata_sis: Remove bogus cable match

2008-12-09T05:44:11Z

Some systems report SIS 5513 as both vendor/id and subvendor/id string. In that case we can't distinguish the system by the id svid/sdid and in fact the entry here breaks some boxes. At some point we need to find another way to detect the Targa Visionary 1000, until then this trades a hang for some users with lower performance for others.

ATA: piix, fix pointer deref on suspend

2008-12-09T05:43:54Z

Hi, I've found this issue in the mmotm 2008-12-02-17-08. -- Commit ata_piix: add borked Tecra M4 to broken suspend list introduced DMI variables checking, but they can be null, so that we possibly dereference null. Check if they are null and avoid checks in that case.

libata: blacklist Seagate drives which time out FLUSH_CACHE when used with NCQ

2008-12-01T18:49:27Z

Some recent Seagate harddrives have firmware bug which causes FLUSH CACHE to timeout under certain circumstances if NCQ is being used. This can be worked around by disabling NCQ and fixed by updating the firmware. Implement ATA_HORKAGE_FIRMWARE_UPDATE and blacklist these devices. The wiki page has been updated to contain information on this issue. http://ata.wiki.kernel.org/index.php/Known_issues Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

[libata] pata_rb532_cf: fix signature of the xfer function

2008-12-01T18:49:17Z

Per definition, this function should return the number of bytes consumed. As the original parameter "buflen" is being decremented inside the read/write loop, save it in "retlen" at the beginning.
