[ANNOUNCE] libata: new EH, NCQ, hotplug and PM patches against stable kernel

[Tejun Heo]

Hello, all.

Lately libata has been going through a lot of changes and even more
are around the corner.  I've been working on error handling and
advanced SATA features for quite sometime now, and, finally, patches
have been finalized and submitted for review a few days ago.

2.6.18 is the target for mainline merge.  As there is quite some time
between now and 2.6.18, I have made patches to update the current
stable kernel to support the new features so that they can receive
wider testing and interested people don't have to wait too long.  I
intend to maintain these patches through 2.6.16 and 17 until the
mainline merge happens.

Added new features are

* New error handling
* IRQ driven PIO (from Albert Lee)
* SATA NCQ support
* Hotplug support
* Port Multiplier support

The following drivers support new features.

ata_piix:	new EH, irq-pio, warmplug (hardware restriction)
sata_sil:	new EH, irq-pio, hotplug
ahci:		new EH, irq-pio, NCQ, hotplug
sata_sil24:	new EH, irq-pio, NCQ, hotplug, Port Multiplier

Please read README carefully before testing the patches.  Keep in mind
that these are still quite experimental and not ready for production
use.

Thanks.
