Dear Linux folks,
With Linux built from commit 4dfc2788033d (Merge tag
'iommu-updates-v4.14'
of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu), I get the
warning below on a Lenovo X60t with a 32-bit CPU.
Indeed. I sent a patch this morning. The warning is harmless -- the
warning condition has a typo.
I get that warning (4 times) with that typo fix:

What's wrong here?
Try Linus' tree now -- it should be fixed.
Yes, done that already, no problems anymore.
Thanks
