      [SCSI] eata_pio cleanup and PCI fix · 1a68d41a
      Alan Cox authored 
      This started as a PCI reference fixup but to do that I need to build it,
to build it I need to fix it and its full of 32bitisms and uglies.

It has been resurrected, I'm not sure if this is a thank you for the
work on the license stuff or punishment for some unknown misdeed however
8). I've also fixed a memory scribble in the init code.

One oddity - the changes from HZ * to constants are deliberate. Whoever
originally wrote the code (or cleaned it up) used HZ for a cycle timing
loop even though is not HZ related. I've put it back to the counts used
in the old days when the driver was most used.

      [SCSI] aacraid: README update · 2538363e
      Mark Haverkamp authored 
      Received from Mark Salyzyn:

This patch to the driver's documentation adds a few new product entries,
sorts the entries on OEM lines first for easy searching, followed by
product id order to make it easier to compare against the open source
pci list. The driver has 'family match' so is somewhat future proof, no
code changes are required to recognize the new products.

      [SCSI] aacraid: remove scsi_remove_device · ac5826ca
      Mark Haverkamp authored 
      Received from Mark Salyzyn:

Until the system is stabilized, I am suggesting the enclosed
modification to prevent the driver from tickling the panic. Once sysfs
and friends are stabilized, the patch may be backed out. We have yet to
evaluate if we really want to relinquish existing Scsi Devices in any
case, holding on to them as configuration of arrays comes and goes makes
some sense as well. As a result, we have opted to pull the lines rather
than comment them in legacy.

      [SCSI] aacraid: merge rx and rkt code · 76a7f8fd
      Mark Haverkamp authored 
      Received from Mark Salyzyn:

The only real difference between the rkt and rx platform modules is the
offset of the message registers. This patch recognizes this similarity
and simplifies the driver to reduce it's code footprint and to improve
maintainability by reducing the code duplication.

Visibly, the 'rkt.c' portion of this patch looks more complicated than
it really is. View it as retaining the rkt-only specifics of the
interface.

      [SCSI] aacraid: expose physical devices · 653ba58d
      Mark Haverkamp authored 
      Received from Mark Salyzyn:

I am placing this functionality into an insmod parameter. Normally the physical
components are exported to sg, and are blocked from showing up in sd.

Note that the pass-through I/O path via the driver through the Firmware to the
physical disks is not an optimized path, the card is designed for Hardware
RAID, elevator sorting and caching. This should not be used as a means for
utilizing the aacraid based controllers as a generic scsi/SATA/SAS controller,
performance should suck by a few percentage points, any RAID meta-data on the
drives will confuse the controller about who owns the drives and there is a
high risk of destroying content in both directions. Unreliable and for
experimentation or strange controlled circumstances only.

      [SCSI] aacraid: misc cleanup · 65101355
      Mark Haverkamp authored 
      Received from Mark Salyzyn:

Basically cleanup, nothing here will have an affect. Adjusting some
error codes, removing superfluous definitions and code fragments.
