The patch titled
ieee1394: extend lowlevel API for address range properties
has been removed from the -mm tree. Its filename is
ieee1394-ieee1394-extend-lowlevel-api-for.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ieee1394: extend lowlevel API for address range properties
From: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>
Host adapter hardware imposes certain restrictions and features on address
ranges. Instead of hard-wiring such ranges into the ieee1394 core or even
into protocol drivers, let lowlevel drivers specify these ranges via struct
hpsb_host.
