Hi Borislav,

This fixes a bug present in kernels today.  Until we have an ETA for
Ingo's stuff to get merged, I'd really hope you can consider taking
bugfixes like these.

BTW, I didn't really expect you to pull this in directly.  I think it's
easier if the entire MPX set is pulled in at once.  Otherwise, the x86
maintainers will have to drop this from the set before merging, and it
might not be 100% obvious how this patch got merged via another route.
