2009-12-03be2net: Changes to print fw command opcode when command is failed by controller.Ajit Khaparde
When a firmware command fails, only the failure codes are printed. It is difficult to co-relate this to the actual command that has failed. These changes will now print the command code that has failed.

2009-12-03ahci: let users know that Promise PDC42819 support is limited to SATA devicesMark Nelson
ahci can drive the Promise PDC42819, but obviously it can only use SATA disks connected to this controller. The controller can actually support SAS disks as well, but we only know how to use it in it's AHCI mode. Add a message to let users know that because ahci is driving their chip they can only use the SATA disks connected to this controller.

2009-12-03pata_hpt{37x|3x2n}: fix timing register masks (take 2)Sergei Shtylyov
These drivers inherited from the older 'hpt366' IDE driver the buggy timing register masks in their set_piomode() metods. As a result, too low command cycle active time is programmed for slow PIO modes. Quite fortunately, it's later "fixed up" by the set_dmamode() methods which also "helpfully" reprogram the command timings, usually to PIO mode 4; unfortunately, setting an UltraDMA mode #N also reprograms already set PIO data timings, usually to MWDMA mode # max(N, 2) timings... However, the drivers added some breakage of their own too: the bit that they set/clear to control the FIFO is sometimes wrong -- it's actually the MSB of the command cycle setup time; also, setting it in DMA mode is wrong as this bit is only for PIO actually and clearing it for PIO modes is not needed as no mode in any timing table has it set... Fix all this, inverting the masks while at it, like in the 'hpt366' and 'pata_hpt366' drivers; bump the drivers' versions, accounting for recent patches that forgot to do it...

2009-12-03pata_cmd64x: implement serialization as per notesAlan Cox
Daniela Engert pointed out that there are some implementation notes for the 643 and 646 that deal with certain serialization rules. In theory we don't need them because they apply when the motherboard decides not to retry PCI requests for long enough and the chip is busy doing a DMA transfer on the other channel. The rule basically is "don't touch the taskfile of the other channel while a DMA is in progress". To implement that we need to - not issue a command on a channel when there is a DMA command queued - not issue a DMA command on a channel when there are PIO commands queued - use the alternative access to the interrupt source so that we do not touch altstatus or status on shared IRQ. Updated to remote extra conditional check Bartlomiej noted and to remove the variables for irq checks as the CMD648 doesn't have the underlying problem.

2009-12-03libata: add translation for SCSI WRITE SAME (aka TRIM support)Christoph Hellwig
Add support for the ATA TRIM command in libata. We translate a WRITE SAME 16 command with the unmap bit set into an ATA TRIM command and export enough information in READ CAPACITY 16 and the block limits EVPD page so that the new SCSI layer discard support will driver this for us. Note that I hardcode the WRITE_SAME_16 opcode for now as the patch to introduce the symbolic is not in 2.6.32 yet but only in the SCSI tree - as soon as it is merged we can fix it up to properly use the symbolic name.

2009-12-03libata: retry failed FLUSH if device didn't fail itTejun Heo
If ATA device failed FLUSH, it means that the device failed to write out some amount of data and the error needs to be reported to upper layers. As retries can't recover the lost data, FLUSH failures need to be reported immediately in general. However, if FLUSH fails due to transmission errors, the FLUSH needs to be retried; otherwise, filesystems may switch to RO mode and/or raid array may drop a drive for a random transmission glitch. This condition can be rather easily reproduced on certain ahci controllers which go through a PHY event after powersave mode switch + ext4 combination. Powersave mode switch is often closely followed by flush from the filesystem failing the FLUSH with ATA bus error which makes the filesystem code believe that data is lost and drop to RO mode. This was reported in the following bugzilla bug. http://bugzilla.kernel.org/show_bug.cgi?id=14543 This patch makes libata EH retry FLUSH if it wasn't failed by the device.

2009-12-03ahci: disable SNotification capability for ich8Shaohua Li
I obseved there is a sata_async_notification() for every ahci interrupt. But the async notification does nothing (this is hard disk drive and no pmp). This cause cpu wastes some time on sntf register access. It appears ICH AHCI doesn't support SNotification register, but the controller reports it does. After quirking it, the async notification disappears. PS. it appears all ICH don't support SNotification register from ICH manual, don't know if we need quirk all ICH.
