51704c609f [PATCH] libata: Use ATA_FLAG_PIO_POLLING for pdc_adma
pdc_adma was overlooked and broken by the irq-pio patch:
Only HSM_ST_LAST interrupts should be delivered to this LLDD.

Adding ATA_FLAG_PIO_POLLING to pdc_adma fixes the problem (temporarily),
before we convert the irq handler of pdc_adma to handle all interrupts.

1049cb4787 [PATCH] libata: add missing ->data_xfer for pdc_adma
pdc_adma use libata-core PIO path but were left out
during ->data_xfer conversion.  Initialize with proper callbacks.

This patch is against the current libata-dev#ALL.  Controllers which
implement their own PIO HSM (ahci and sil24) don't need ->data_xfer, so the
above two are the only drivers which were left out during conversion.

9227c33de8 [PATCH] move ->eh_strategy_handler to the transport class
Overriding the whole EH code is a per-transport, not per-host thing.
Move ->eh_strategy_handler to the transport class, same as
->eh_timed_out.

Downside is that scsi_host_alloc can't check for the total lack of EH
anymore, but the transition period from old EH where we needed it is
long gone already.

30afc84cf7 [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.

a7dac447bb [libata] change ata_qc_complete() to take error mask as second arg
The second argument to ata_qc_complete() was being used for two
purposes: communicate the ATA Status register to the completion
function, and indicate an error.  On legacy PCI IDE hardware, the latter
is often implicit in the former.  On more modern hardware, the driver
often completely emulated a Status register value, passing ATA_ERR as an
indication that something went wrong.

Now that previous code changes have eliminated the need to use drv_stat
arg to communicate the ATA Status register value, we can convert it to a
mask of possible error classes.

This will lead to more flexible error handling in the future.

ac19bff25b [libata] ensure ->tf_read() hook reads Status and Error registers
We want ->tf_read() to get a complete snapshot of all taskfile
registers, without requiring the callers to manually call
ata_chk_status() and ata_chk_err() themselves.

This also fixes a minor bug in sata_vsc where the lower bits of the
feature register were incorrectly placed in the HOB (high order bits)
portion of struct ata_taskfile.
