The patch titled
IPMI: fix timeout list handling
has been removed from the -mm tree. Its filename was

------------------------------------------------------
Subject: IPMI: fix timeout list handling
From: David Barksdale <amatus@xxxxxxxxxx>
Fix a dangling pointer bug in ipmi_timeout_handler. A list of timedout
messages is not re-initialized before reuse, causing the head of the list
to point to freed memory.
