Stefan Bader - July 2, 2010, 7:43 a.m.
As of today, this change is upstream but as two separate patches. I took the
liberty to do provide them as backported in your name.
Both have the necessary tags to make them go upstream stable and should come in
one of the next stable releases. But due to the fact that an installation is not
possible without that changes on the affected hw, I think it is sensible to take
them pre-stable. Changes are limited to specific device, so regression potential
is low.

-Stefan

For the split up version of patches.

I think this patch should have removed the conditional above as it is
now encoded into the driver_data field for the Cenatek devices.  Though
it remaining is benign.  Tejun you probabally want to kill that for the
upstream version.

Oh, right, forgot about that.  Will kill it in mainline.

Thanks.

Subject: [PATCH 2/2] (pre-stable) ata_generic: implement ATA_GEN_* flags and force enable DMA on MBP 7,1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BugLink: http://bugs.launchpad.net/bugs/576601

IDE mode of MCP89 on MBP 7,1 doesn't set DMA enable bits in the BMDMA
status register.  Make the following changes to work around the problem.

* Instead of using hard coded 1 in id->driver_data as class code
  match, use ATA_GEN_CLASS_MATCH and carry the matched id in
  host->private_data.

* Instead of matching PCI_VENDOR_ID_CENATEK, use ATA_GEN_FORCE_DMA
  flag in id instead.

* Add ATA_GEN_FORCE_DMA to the id entry of MBP 7,1.
