The patch titled
lock validator: reenable NMIs
has been added to the -mm tree. Its filename is

See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: lock validator: reenable NMIs
From: Ingo Molnar <mingo@xxxxxxx>
- not touch the irqtrace state in NMI handlers
- re-enable NMIs and oprofile on i386 and x86_64
I have tested this with high-rate (10 KHz per CPU) NMI load on the kernel,
and while previously we'd quickly get the irqtrace state confused and a
lock validator bug message, with this patch applied it's now working fine.
(Note that on x86_64 we only build one variant of the paranoid-exit
codepath if IRQTRACE is disabled - so there should be no difference in code
generated, as long as the validator is disabled)
