Subject: [PATCH] libata: return AC_ERR_* from issue functions

Return AC_ERR_* mask from issue fuctions instead of 0/-1.  This
enables things like failing a qc with AC_ERR_HSM when the device
doesn't set DRDY when the qc is about to be issued.

Subject: [PATCH] libata: implement and apply ata_eh_qc_complete/retry()

Implement ata_eh_qc_complete/retry() using scsi_eh_finish_cmd() and
scsi_eh_flush_done_q().  This removes all eh scsicmd finish hacks from
low level drivers.

This change was first suggested by Jeff Garzik.

Subject: [libata sata_promise] add correct read/write of hotplug registers for
 SATAII devices

This patch adds support for correctly masking out and knowing about
hotplug events on Promise SATAII150 Tx4/Tx2 Plus controllers.

Also, a kmalloc->kzalloc cleanup.

Subject: [PATCH] libata: kill NULL qc handling from ->eng_timeout callbacks

->eng_timeout cannot be invoked with NULL qc anymore.  Add an
assertion in ata_scsi_error() and kill NULL qc handling from all
->eng_timeout callbacks.

Subject: [PATCH] libata: kill sht->max_sectors

The previous dev->max_sectors patch made sht->max_sectors meaningless.
Kill all initializations of sht->max_sectors.

Subject: [SCSI] libata: implement minimal transport template for
 ->eh_timed_out

SCSI midlayer has moved hostt->eh_timed_out to transport template.  As
libata doesn't need full-blown transport support yet, implement
minimal transport for libata.  No transport class or whatsoever, just
empty transport template with ->eh_timed_out hook.
