Hrm, it looks like at least Ubuntu's kernel security test suite expects to find these entries (when it verifies that STRICT_DEVMEM hasn't regressed). Also, the commit only removed the entries on x86. Most (all?) of the other architectures still have them. Could you revert this for now, and I'll cook up a %pK-based solution for -next? -Kees -- Kees Cook Chrome OS & Brillo Security
