Hi,
a minor update:

I have found and modified/applied a patch which silences the RCU issue report 

	[ INFO: suspicious RCU usage. ]
	include/trace/events/rpm.h:63 suspicious rcu_dereference_check() usage!

on our OMAP3 devices:

	http://git.goldelico.com/?p=gta04-kernel.git;a=commit;h=bebd0abff4b75f5e2a35af067833e5a7f57fea49

I don't know if this patch is somewhere in the pipeline to appear in linux-next.
Other patches from the same patch set are in linus/master for a while and two
were merged last week.

So let's track if it arrives upstream. If not, we can report to the author on LKML
and ask where it got stuck.

BR,
Nikolaus
