The patch titled
ata_piix: strip now unneded MAP related stuff
has been removed from the -mm tree. Its filename was
ata_piix-strip-now-unneded-map-related-stuff.patch
This patch was dropped because Jeff trashed it all and I'm not confident in my repairs
------------------------------------------------------
Subject: ata_piix: strip now unneded MAP related stuff
From: Tejun Heo <htejun@xxxxxxxxx>
Now that PCS isn't used for device detection anymore...
* esb_sata is identical to ich5_sata
* no reason to know present_shift
* no reason to store map_db in host private area
The MAP table itself is left because it can be used for SCR access.
