[CVE-2016-3857] local privilege escalation under CONFIG_OABI_COMPAT

[Luis Henriques]

Initially I believed this CVE was Android-specific, but it actually
affects kernels with CONFIG_OABI_COMPAT enabled.  This means that Precise
kernels need this fix -- I've checked all other kernels and this config is
disabled (although this patch applies cleanly).
