- change interface of the reset functions from Scsi_Cmnd to Scsi_Host.
- add functions with the original interface and rename the new
functions to reflect the new interface.
- call these from the pcmcia driver, thereby avoiding the need to
construct a (broken) Scsi_Cmnd from a Scsi_Host.
- just run the bh if the interrupt is from the controller and if so
ensure that it's only called once per interrupt.

In order to use the new execute_in_process_context() API, you have to
provide it with the work storage, which I do in SCSI in scsi_device and
scsi_target, but which also means that we can no longer queue up the
target reaps, so instead I moved the target to a state model which
allows target_alloc to detect if we've received a dying target and wait
for it to be gone. Hopefully, this should also solve the target
namespace race.

When the locking was changed in the eh code ips_eh_reset was changed
so that it was a wraper around __ips_eh_reset and all ips_eh_reset
does is grab the host lock and then calls __ips_eh_reset.
In the queuecommand, ips_queue is called with the host_lock held so if
it calls ips_eh_reset we will have a problem. This patch just has
ips_queue call __ips_eh_reset.
Patch is only compile tested. I do not have the HW.

Silicon Image has disclosed a new sil3114/3152 errata and workaround
which causes the controller to return R_ERR on DMA activate FIS if the
FIS is received while the next PRD is being fetched. This patch
implements the workaround.
This errata results in lock up and doesn't trigger if m15w workaround
is in effect. We stopped applying m15w to 3512 and 3114 in 2.6.14-rc1
which makes 3512/3114 lock up with some drives on all kernel versions
since 2.6.14-rc1 upto now (2.6.16-rc4). This patch should fix the
regression.

Separate out ata_dev_read_id() from ata_dev_identify(). This is the
first half of splitting ata_dev_identify(). ata_dev_read_id() will
also be used for revalidation. This patch does not make any behavior
change.
ata_dev_read_id() doesn't modify any of libata-internal data
structures. It simply reads IDENTIFY page and returns error code on
failure. INIT_DEV_PARAMS and EDD wrong class code are also handled by
this function.
Re-reading IDENTIFY after INIT_DEV_PARAMS is performed by jumping to
retry: instead of calling ata_dev_reread_id(). This is done because
1. there's retry label anyway 2. ata_dev_reread_id() cannot be used
anywhere else so there's no reason to keep it.
This function is probably the place to set transfer mode to PIO0
before IDENTIFY. However, reset -> identify -> init_dev_params order
should be kept for pre-ATA4 devices so we cannot set transfer mode
before IDENTIFY for them. How do we know if a device is post-ATA4
before IDENTIFY?

For ATAPI commands, padding can reduce qc->n_elem by one and thus to

fail for legal commands. This patch fixes the assert()'s to take
qc->pad_len into account.
Although the condition check seems a bit excessive, as this part of
code isn't still stable yet, I think it's worth to keep those.
