The patch titled
fix I/OAT for kexec
has been removed from the -mm tree. Its filename was
fix-i-oat-for-kexec.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: fix I/OAT for kexec
From: Dan Aloni <da-x@xxxxxxxxxxxxx>
Under kexec, I/OAT initialization breaks over busy resources because the
previous kernel did not release them.
I'm not sure this fix can be considered a complete one but it works for me.
I guess something similar to the *_remove method should occur there..
