The patch titled
IPMI: add 0.9 support
has been removed from the -mm tree. Its filename was
ipmi-add-09-support.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: IPMI: add 0.9 support
From: Corey Minyard <cminyard@xxxxxxxxxx>
Add support for IPMI 0.9 systems to the IPMI driver. Just handle a shorter
get device ID command with less information.
