This is the fourth submission of this patch. I have still
had no response from the maintainer.
Adds AMI Megaraid Elite 1600 to the list of supported

megaraid driver with this card, so I wrote this patch and
have been running without
this...

I'm not sure how you would do this since there is currently no way to
embed data in a cdev. Also, since there are multiple cdevs per scsi_tape,
it seems cleaner to use a new kref.

Do you want me to rediff your patches on top of this one,
or do you want to keep the entire MSI series together
and do the rediff? Otherwise the patches seem fine.
Thanks,
Brian

This needs a Signed-off-by: from you as well, since you transmitted the
patch to me. I assume it was just omitted in error and have added it in
the git repository.

Switch device scanning logic in the ipr driver to use
the async scan API. This speeds up boot times, particularly
on large systems.

/O outstanding to the adapter, which
there shouldn't be, place the adapter into a state
where it has no memory of any DMA addresses from the old
kernel, then disable the device. This significantly
speeds up kexec boot, particularly in configurations with
multiple ipr adapters.

Add a memory barrier prior to sending a new command to the VIOS
to ensure the VIOS does not receive stale data in the command buffer.
Also add a memory barrier when processing the CRQ for completed commands.

Both ibmvscsi and ibmvfc are still very much in use on IBM Power hardware.
ibmvfc is specific to NPIV configurations, while ibmvscsi can use
